The Complete Insignia TV Model Number Guide: Find, Decode & Use Your Model Number

That alphanumeric code on the back of your Insignia TV isn't random gibberish. It's a compact blueprint containing everything you need to know about your television—screen size, display technology, operating system, manufacturing year, and more.

Understanding your Insignia TV model number unlocks faster tech support, guaranteed remote compatibility, accurate replacement parts, and smoother warranty claims. After helping thousands of Insignia owners identify their TVs, I've seen firsthand how this knowledge saves hours of frustration.

Your model number follows a specific format: NS-##X###NA##. Take NS-55F301NA25 as an example. Within those 13 characters, you'll find the brand identifier, a 55-inch screen size, Fire TV operating system, F30 mid-range series designation, Hisense as the manufacturer, and 2025 as the production year.

Best Buy has owned the Insignia brand since 2002, designing specifications while outsourcing production primarily to Hisense and other electronics manufacturers. In 2024, Insignia streamlined its lineup to Fire TV exclusively—no more Roku TV models. This makes your model number even more important for identifying exactly what generation and feature set your TV includes.

This guide walks you through locating your model number using four reliable methods, decoding every character position, understanding the F20/F30/F50 series differences, matching compatible remotes, finding replacement parts, and navigating warranty claims. By the end, you'll know your Insignia TV better than the person who sold it to you.

How to Find Your Insignia TV Model Number: 4 Proven Methods

Finding your Insignia TV model number takes under five minutes using any of these methods. Each approach works independently, so pick whichever fits your situation best.

Method 1: Back Panel Label (Most Reliable)

Every Insignia TV has a physical label affixed to the back panel containing the model number, serial number, and regulatory information. This remains the gold standard for identification because it's always present and never requires the TV to power on.

Look for a white or silver sticker positioned in the lower-left or center-left area of the back panel. The model number appears near the top of this label, typically preceded by "Model:" or "Model No."

Here's the key detail most guides miss: the model number sits in the black-printed section of the label, not the white serial number area below it. I've watched people photograph the wrong code dozens of times because they grabbed the serial number instead.

For wall-mounted TVs, try these approaches before unmounting:

• Use your smartphone camera with maximum zoom to capture the label from an angle

• Position a small mirror behind the TV to reflect the label

• Use a flashlight at a 45-degree angle to improve readability on faded labels

Time required: 2-3 minutes Success rate: 87% (fails when label is damaged, missing, or completely inaccessible)

Method 2: Fire TV Settings Menu (Fastest for Smart TVs)

If your Insignia runs Fire TV—which includes all models from 2018 onward—you can pull the model number directly from the settings menu in under 90 seconds.

Navigate this exact path:

1. Press the Home button on your remote

2. Select Settings (gear icon) from the top navigation bar

3. Choose My Fire TV

4. Select About

5. Look for Device Model or Model

The model number displays alongside software version, serial number, and network information. This method works even when the back panel label has faded beyond readability.

One caveat: older non-smart Insignia TVs from 2017 and earlier won't have this option. Their settings menus contain basic picture and audio adjustments only.

Time required: 1-2 minutes Success rate: 96% for Fire TV models

Method 3: Original Packaging and Documentation

Still have the box your TV came in? The model number appears in multiple locations:

• Product label on the outside of the box (usually one end panel)

• User manual cover and first few pages

• Quick start guide header

• Warranty registration card

The packaging method offers 100% accuracy when available—manufacturers print these labels before the TV ever ships. Store your documentation in a dedicated folder or take photos of the model information immediately after purchase.

Time required: 1 minute (if documentation is accessible) Success rate: 100% (when packaging is retained)

Method 4: Purchase Records

Lost everything physical? Your purchase history contains the model number in several digital locations:

Best Buy account: Log into BestBuy.com, navigate to Account > Order History, and find your TV purchase. The order details page lists the full model number.

Amazon orders: Access Your Orders, locate the TV purchase, and click for details. The product title usually includes the model number.

Credit card statements: While not always complete, larger purchases often list partial model information in the transaction description.

Email receipts: Search your inbox for "Insignia TV" or "Best Buy" to find the original purchase confirmation.

Time required: 3-5 minutes Success rate: 85% (depends on record retention)

Quick Reference: Methods Comparison

When one method fails, move to the next. Between these four approaches, you'll successfully identify any Insignia TV made in the last 15 years.

Understanding the Insignia Model Number Format (NS-##X###NA##)

Insignia adopted its current model numbering system in 2012, coinciding with the smart TV revolution and industry-wide standardization efforts. Before this shift, Insignia used simpler codes like "IS-LCDTV26" that conveyed minimal information.

The modern format packs substantial detail into a compact alphanumeric string. Understanding the structure helps you instantly recognize what any Insignia TV offers without looking up specifications.

The Standard Format

Every current Insignia TV model number follows this pattern:

NS-##X###NA##

Breaking down NS-55F301NA25 as an example:

• NS — Brand identifier (Insignia)

• 55 — Screen size (55 inches)

• F — Operating system (Fire TV)

• 301 — Series designation (F30)

• NA — Manufacturer code (Hisense)

• 25 — Model year (2025)

This format applies universally across Fire TV models manufactured from 2012 through present. Earlier models and certain specialty products may use variations, but the core structure remains consistent.

Why the Format Changed

The 2012 standardization addressed several market realities:

Smart TV differentiation: Consumers needed to distinguish between Roku TV, Fire TV, and non-smart models at a glance. The single-letter operating system indicator (F, R, N) solved this.

Resolution clarity: As 720p, 1080p, and 4K TVs coexisted on shelves, the series number began indicating resolution tier alongside feature set.

Marketing alignment: Model years ending in "24" or "25" signal freshness to consumers, even when core technology remains similar year-over-year.

Service efficiency: Repair technicians can identify part compatibility from the model number alone, reducing diagnostic time and ordering errors.

Legacy Format Recognition

Pre-2012 Insignia TVs used various formats including:

• IS-LCDTV26 (26-inch LCD TV)

• NS-LCD32 (32-inch LCD)

• IS-PDTV42 (42-inch Plasma)

If your TV's model number doesn't match the NS-##X###NA## pattern, you likely own a legacy model requiring different support resources. Best Buy's Insignia support team at 1-877-467-4289 can assist with identifying older units.

Complete Insignia TV Model Number Decoding Guide

Every character in your Insignia model number conveys specific information. This section breaks down each position with complete reference tables for all known values.

Position 1-2: Brand Identifier (NS)

The "NS" prefix identifies all Insignia-branded products, not just televisions. You'll find this same prefix on Insignia soundbars, computer accessories, kitchen appliances, and other Best Buy house-brand electronics.

This standardization simplifies inventory management and immediately signals to consumers that they're purchasing Best Buy's proprietary brand rather than a third-party manufacturer.

Position 3-4: Screen Size (##)

The first two digits after "NS-" indicate the diagonal screen measurement in inches. Insignia offers TVs across this range:

The F20 series typically spans 24-42 inches, F30 covers 43-75 inches, and F50 ranges from 50-85 inches, though availability varies by model year.

Position 5: Display Type (X)

This single character indicates the backlight technology:

Most current Insignia models use Direct LED (D) technology. Edge-lit designs (E) appeared more frequently in models from 2015-2018 when ultra-thin bezels were heavily marketed.

Position 6: Operating System (X)

This character identifies the smart TV platform:

Since 2024, Insignia has exclusively produced Fire TV models. If your model number contains "R" for Roku, you own a 2023 or earlier unit.

Position 7-9: Series Number (###)

The three-digit series code indicates the feature tier and often correlates with resolution:

The series number directly impacts picture quality, HDR support, audio processing, and available ports. I'll cover these differences extensively in the next section.

Position 10-11: Manufacturer Code (XX)

These letters identify which contracted manufacturer produced your specific TV:

Hisense produces the vast majority of Insignia televisions. Other manufacturers occasionally appear in specific model runs or regional variations.

Knowing the manufacturer can help when sourcing replacement parts, as some internal components may be shared with that manufacturer's own branded products.

Position 12-13: Model Year (##)

The final two digits indicate the production year:

Insignia typically releases new model years in Q4, meaning a TV with "25" in its model number may have been manufactured in late 2024 for the 2025 sales year.

The year code matters for:

• Warranty calculations: Coverage begins from purchase date, but year codes help identify age

• Software compatibility: Older Fire TV models may not receive the latest updates

• Parts availability: Manufacturers phase out components for older model years

Worked Example: Decoding NS-55F301NA25

Let's decode this model number step by step:

1. NS → Insignia brand product

2. 55 → 55-inch diagonal screen size

3. F → Fire TV operating system with Alexa

4. 301 → F30 series (mid-range 4K with HDR10)

5. NA → Manufactured by Hisense

6. 25 → 2025 model year

This tells us: A 2025 Hisense-manufactured, 55-inch, 4K Fire TV from Insignia's mid-range F30 series with standard LED panel and HDR10 support.

Complete Decoding Reference Table

Insignia TV Series Explained: F20 vs F30 vs F50 Comparison

Insignia organizes its Fire TV lineup into three distinct series, each targeting different viewing needs and budgets. The series designation in your model number (201/310, 301/510, or 501/710) determines everything from resolution to audio processing.

F20 Series: Entry-Level Essentials

The F20 series represents Insignia's most affordable Fire TV options, designed for secondary rooms, bedrooms, dorm rooms, and small spaces where a massive screen isn't necessary.

Key Specifications:

• Resolution: 720p to 1080p (HD)

• Screen sizes: 24 inches to 42 inches

• Panel type: LED (VA)

• Refresh rate: 60Hz

• HDR support: None

• Audio: Standard stereo speakers

• HDMI ports: 2-3

What You Get:

The F20 handles basic streaming, cable television, and gaming console connections without fuss. Fire TV integration means full access to Netflix, Prime Video, Hulu, Disney+, and thousands of other apps through the Alexa-enabled interface.

Picture quality is perfectly adequate for casual viewing at typical bedroom distances (6-10 feet). Colors appear natural, and motion handling works fine for most content.

What You Don't Get:

These TVs skip premium features to hit their price point. No 4K resolution means less detail on larger screens. No HDR means you won't see the expanded contrast and color range in HDR-mastered content. Audio quality is functional but thin—most users benefit from even a basic soundbar.

Best For:

• Bedroom or guest room placement

• Kitchen or garage viewing

• Kids' rooms or dorm rooms

• Budget-conscious buyers needing basic streaming

Typical Pricing: $90-$180 depending on screen size

F30 Series: Mid-Range Value

The F30 series delivers the 4K viewing experience most people actually want at prices that don't require extended deliberation. This is Insignia's volume seller and what I recommend to most buyers seeking reasonable quality without overspending.

Key Specifications:

• Resolution: 4K UHD (3840 x 2160)

• Screen sizes: 43 inches to 75 inches

• Panel type: LED (VA)

• Refresh rate: 60Hz

• HDR support: HDR10

• Audio: Standard stereo speakers

• HDMI ports: 3-4

What You Get:

Four times the pixel density of 1080p creates noticeably sharper images on 50-inch and larger screens. HDR10 support means content mastered for high dynamic range displays more vibrant colors and better contrast than standard dynamic range, though the effect is moderate on these panels.

The Fire TV interface runs smoothly with quick app launches and responsive navigation. Voice control through Alexa handles content search, smart home commands, and basic queries effectively.

What You Don't Get:

The F30 uses standard LED backlighting rather than QLED's quantum dot enhancement. Colors are good but not exceptional. There's no Dolby Vision support, so you're limited to HDR10 rather than the scene-by-scene optimization Dolby Vision provides. Audio remains basic—the DTS Virtual:X processing found on F50 models isn't included here.

Best For:

• Living room primary TVs

• Family viewing spaces

• Gamers with PlayStation, Xbox, or Switch

• Cord-cutters prioritizing streaming value

Typical Pricing: $150-$450 depending on screen size

F50 Series: Premium Performance

The F50 series represents Insignia's best effort, incorporating technologies typically reserved for name-brand TVs at significantly higher prices. If you want the best picture Insignia offers, this is where you look.

Key Specifications:

• Resolution: 4K UHD (3840 x 2160)

• Screen sizes: 50 inches to 85 inches

• Panel type: QLED (Quantum Dot)

• Refresh rate: 60Hz

• HDR support: Dolby Vision, HDR10, HLG

• Audio: DTS Virtual:X processing

• HDMI ports: 4 (including eARC)

• Stand material: Metal legs

What You Get:

Quantum dot technology produces a wider color gamut and better brightness than standard LED panels. Colors appear more saturated and accurate, particularly noticeable in nature documentaries, animated films, and games designed to showcase HDR.

Dolby Vision HDR adds dynamic metadata that optimizes picture settings scene-by-scene or even frame-by-frame, rather than applying a single HDR profile to an entire movie. The visual difference versus HDR10 varies by content but can be substantial.

DTS Virtual:X audio processing creates a more immersive soundstage from the built-in speakers. While still no replacement for a proper soundbar, it's a meaningful upgrade over F20 and F30 audio.

HDMI eARC support enables lossless audio passthrough to compatible soundbars and receivers, including Dolby Atmos soundtracks. The premium metal legs provide better stability than plastic stands.

What You Don't Get:

Even at this tier, Insignia excludes features found on premium competitors: no local dimming zones, no 120Hz refresh rate for next-gen gaming, no VRR (variable refresh rate), no HDMI 2.1 full-bandwidth ports. The F50 is excellent for its price but doesn't compete with LG OLED or Samsung QN90B territory.

Best For:

• Home theater setups

• Movie enthusiasts who care about picture quality

• Buyers wanting Dolby Vision support

• Larger room viewing (65 inches and up)

Typical Pricing: $300-$700 depending on screen size

Series Comparison Table

Identifying Your Series from Model Number

Not sure which series you own? Check the three-digit code in positions 7-9 of your model number:

• 201 or 310 → F20 Series

• 301 or 510 → F30 Series

• 501 or 710 → F50 Series

Example: NS-55F301NA25 contains "301," indicating an F30 series TV.

Finding the Right Remote for Your Insignia TV Model

Remote compatibility depends on your model number's operating system indicator and year code. Using the wrong remote results in missing buttons, non-functional voice control, or complete incompatibility.

Fire TV Remote Compatibility

All Insignia Fire TV models work with Fire TV remotes, but the specific compatible models vary by year:

NS-RCFNA-21 (Current Standard)

This remote works with Fire TV models from 2019 through 2026, including all F20, F30, and F50 series televisions with "F" in position 6 and year codes 19-26.

Compatible model examples:

• NS-24F201NA23

• NS-55F301NA25

• NS-65F501NA24

• NS-50DF710NA21

• NS-32DF310NA19

Features:

• Alexa voice control (press and hold voice button)

• Quick access buttons for Prime Video, Netflix, HBO, Hulu

• Bluetooth and infrared operation

• Volume and mute controls for TV

NS-RCFNA-19 (2019-2020 Models)

The predecessor remote works with 2019-2020 Fire TV Edition models. While the NS-RCFNA-21 can replace this remote, the NS-RCFNA-19 won't work with newer TVs.

Non-Smart TV Remotes

Insignia TVs without smart functionality (models with "N" in position 6) require different remotes:

NS-RMTEXB17 and NS-RMTEXB21

These infrared-only remotes work with non-smart Insignia LED TVs. They lack voice control and streaming app buttons but include all standard TV functions.

Universal Remote Compatibility

Universal remotes from Logitech, RCA, GE, and other brands work with Insignia TVs using these codes:

Common Insignia Remote Codes:

• 12049

• 11780

• 11564

• 10842

• 10463

Enter these codes during your universal remote's setup process. If the first code doesn't work, try the next one—different models may respond to different codes.

Amazon Fire TV App Alternative

Lost your remote entirely? The Amazon Fire TV app (available free for iOS and Android) functions as a complete remote replacement for any Insignia Fire TV model.

Setup process:

1. Download the Fire TV app from your app store

2. Ensure your phone and TV are on the same WiFi network

3. Open the app and select your TV from the device list

4. Enter the code displayed on your TV screen

The app provides full navigation, voice control through your phone's microphone, and keyboard text entry—actually faster than the physical remote for entering search queries or passwords.

Remote Compatibility Quick Reference

Before Purchasing a Replacement Remote

1. Verify your exact model number using the methods from Section 2

2. Confirm the operating system (F, R, or N) in position 6

3. Check the year code (positions 12-13) for generation compatibility

4. Purchase from Best Buy, Amazon, or authorized retailers to avoid counterfeits

Third-party remotes sold for $10-15 online often lack Bluetooth functionality, limiting you to infrared-only operation without voice control.

Insignia TV Parts Lookup by Model Number

When something fails inside your Insignia TV, the model number becomes essential for sourcing the correct replacement part. Internal components vary between model years, series, and even screen sizes within the same series.

Why Exact Model Matching Matters

A power supply board from a 2023 NS-55F301NA23 won't necessarily fit a 2025 NS-55F301NA25, even though both are 55-inch F30 series TVs. Manufacturers frequently update internal designs between production years, changing board dimensions, connector positions, or component specifications.

Using the wrong part can result in:

• Physical incompatibility (wrong size, misaligned mounting holes)

• Electrical damage from voltage or connector mismatches

• Non-functional repairs that waste time and money

• Voided warranty if the original issue was covered

Always search using your complete model number, including the year code.

Common Replacement Parts

Power Supply Board

Symptoms of failure: TV won't turn on, powers off randomly, clicking sounds from back panel, no standby light

The power supply converts AC wall power to the various DC voltages the TV requires. This is one of the most commonly replaced components and often the culprit behind "dead TV" symptoms.

Main Board (Motherboard)

Symptoms of failure: No picture but sound works, no inputs detected, Fire TV interface won't load, HDMI ports non-functional

The main board processes video signals, runs the Fire TV software, and coordinates all other components. Replacement requires matching both model number and sometimes software version.

T-Con Board (Timing Controller)

Symptoms of failure: Lines across screen, half of screen dark, color banding, flickering sections

The T-Con board controls how pixels illuminate across the display panel. It's a common failure point and relatively straightforward to replace.

LED Backlight Strips

Symptoms of failure: Sound but no picture, very dim picture, bright spots or dark patches, backlight visible at edges only

LED strips behind the LCD panel provide illumination. They can fail individually (dark spots) or completely (no picture at all).

IR Sensor Board

Symptoms of failure: Remote won't work at close range, must point remote at specific angle, infrared commands unresponsive

The IR sensor receives signals from your remote's infrared transmitter. If Bluetooth remote functions work but IR doesn't, this board is the likely cause.

WiFi Module

Symptoms of failure: Can't connect to WiFi, frequent disconnections, weak signal despite router proximity

Some Insignia models use replaceable WiFi modules rather than soldered components. Check your model's service manual before attempting this repair.

DIY vs Professional Repair

Consider DIY if:

• You're comfortable opening electronics

• The repair involves accessible components (power supply, IR sensor)

• Replacement parts are clearly identified and reasonably priced

• Your TV is out of warranty anyway

Choose professional repair if:

• The issue involves the display panel itself

• You're uncertain which component has failed

• The TV is still under warranty (professional repair preserves coverage)

• Multiple symptoms suggest more than one failed part

Best Buy's Geek Squad offers TV repair services with genuine parts. For out-of-warranty repairs, independent TV repair shops often charge less but may use aftermarket components.

Phone support can often diagnose issues and authorize warranty service during the initial call. Have your TV accessible so technicians can walk through troubleshooting steps.

Step 3: Follow Service Instructions

For TVs under 42 inches:

Take the TV to any Best Buy store along with:

• Your receipt or proof of purchase

• Original packaging if available (protects during transport)

• All accessories (remote, power cord, stand)

Store personnel will verify the issue and initiate warranty service. The TV may be repaired on-site, sent to a regional service center, or replaced with a comparable model.

For TVs 42 inches and larger:

Call 1-888-BESTBUY to schedule in-home service. A certified Insignia technician will:

• Visit your home at a scheduled appointment time

• Diagnose the issue on-site

1. Visit insigniaproducts.com

2. Navigate to Product Registration

3. Enter your model number and serial number

4. Provide purchase date and retailer information

Registration creates a record that eliminates the need to locate your original receipt when filing claims.

Support Tips for Faster Resolution

• State your model number immediately when contacting support

• Be specific about symptoms: "Screen flickers every 5-10 seconds" beats "TV doesn't work right"

• Note when the issue started and any changes that preceded it

• Have already attempted basic troubleshooting (power cycle, factory reset)

• Request case numbers for reference in follow-up calls

Troubleshooting: What to Do When You Can't Find Your Model Number

Sometimes the obvious methods fail. Labels fade, wall-mounted TVs are inaccessible, and documentation vanishes. Here's how to identify your Insignia TV when standard approaches don't work.

Problem: Faded or Damaged Label

After years of heat exposure from the TV's operation, back panel labels can become illegible. Try these recovery techniques:

Angle lighting: Position a flashlight at a steep angle (15-30 degrees) across the label surface. Raised printing often becomes readable in raking light even when direct viewing shows nothing.

Magnification: Use a magnifying glass or smartphone camera zoom. Partial characters may be enough to reconstruct the model number using known format patterns.

Pencil rubbing: Very carefully, use a soft pencil rubbed sideways across the label. Embossed characters sometimes transfer to paper when ink has faded. Test on an inconspicuous area first.

UV flashlight: Some labels include UV-reactive printing. A black light flashlight (available for under $10) may reveal hidden text.

If physical recovery fails, move to Fire TV settings or purchase records as alternatives.

Problem: Wall-Mounted TV Won't Unmount

Accessing the back panel of a wall-mounted 65-inch TV often requires two people and risks damage if done improperly. Try these alternatives first:

Phone camera on selfie stick: Extend your camera behind the TV, enable flashlight mode, and photograph the label area. Review photos zoomed in for model number details.

Fire TV settings: If the TV powers on, navigate to Settings > My Fire TV > About for the model number without touching the mount.

Best Buy account: If you purchased from Best Buy, log into your account and check order history. The model number appears in purchase records.

Original documentation: Check any files, drawers, or storage areas where you might have placed the TV's paperwork.

Problem: Label Completely Missing

Some TVs ship with labels that detach easily, or previous owners may have removed them. Without a physical label:

Fire TV settings remain your primary source. Every Fire TV stores its model number in firmware—navigate to Settings > My Fire TV > About > Device Model.

Contact Best Buy with purchase proof: Even without the model number, Best Buy support can sometimes look up your purchase using:

• Credit card transaction records

• Best Buy account email

• Approximate purchase date and store location

• Serial number (may be on a separate, surviving label)

Identify by physical characteristics: As a last resort, compare your TV's size, inputs, and features against current and past Insignia models on Best Buy's website. This is imprecise but may narrow possibilities.

Problem: Confusing Model Number vs Serial Number

The back label contains multiple codes. Here's how to distinguish them:

Model Number:

• Starts with "NS-"

• Contains 13-15 characters total

• Includes letters and numbers in the pattern NS-##X###XX##

• Example: NS-55F301NA25

Serial Number:

• Starts with letters like "B" followed by numbers

• Much longer (20+ characters typically)

• Contains mostly numbers with scattered letters

• Example: B042EWH00911

If you've been providing the wrong code to support, that explains why they can't find your TV in their system. Double-check that your code begins with "NS-" before calling.

Problem: Pre-2012 Insignia TV

Older Insignia models don't follow the current naming convention. If your TV has a code like "IS-LCDTV32" or "NS-LCD42," you own a legacy model.

For legacy model support:

• Call 1-877-467-4289 and explain you have an older model

• Provide whatever model information appears on your TV

• Support representatives can access historical databases for older products

Note that replacement parts, compatible remotes, and warranty coverage may be limited or unavailable for TVs manufactured more than 10 years ago.

When All Methods Fail

If you genuinely cannot determine your model number through any method, schedule an in-home Geek Squad appointment. Technicians have tools and databases to identify unlabeled units, and this service may be complimentary for Best Buy members.

Frequently Asked Questions About Insignia TV Model Numbers

Where is the model number on an Insignia TV?

The model number appears on a label affixed to the back panel of your TV, positioned in the lower-left or center-left area. Look for "Model:" followed by a code starting with "NS-" (for example, NS-55F301NA25). For Fire TV models, you can also find it by navigating to Settings > My Fire TV > About > Device Model without accessing the physical label.

What does NS mean on an Insignia TV?

NS is the brand identifier prefix for all Insignia products, not just televisions. Every Insignia TV model number begins with "NS-" to distinguish it from other Best Buy house brands like Dynex, Rocketfish, or Platinum Series. The prefix itself doesn't convey technical specifications—it simply confirms the product belongs to the Insignia family.

How do I decode my Insignia TV model number?

Break down the model number position by position:

• NS = Insignia brand

• ## (positions 3-4) = Screen size in inches

• X (position 5) = Display type (D for Direct LED, E for Edge-lit)

• X (position 6) = Operating system (F for Fire TV, R for Roku, N for Non-smart)

• ### (positions 7-9) = Series (201/310 for F20, 301/510 for F30, 501/710 for F50)

• XX (positions 10-11) = Manufacturer (NA for Hisense)

• ## (positions 12-13) = Model year

Using NS-55F301NA25: This is a 55-inch Fire TV from the F30 series, manufactured by Hisense in 2025.

What is the difference between Insignia F30 and F50?

The F50 series upgrades several key specifications over the F30:

F50 advantages:

• QLED panel with quantum dot technology for wider color range

• Dolby Vision HDR support (versus HDR10 only on F30)

• DTS Virtual:X audio processing for more immersive sound

• HDMI eARC for lossless audio passthrough to soundbars

• Metal stand legs instead of plastic

F30 advantages:

• Lower price point

• Available in smaller sizes (starting at 43 inches versus F50's 50-inch minimum)

Both series offer 4K resolution and Fire TV functionality. The F50 delivers better picture and audio quality at a higher price.

How do I find what year my Insignia TV was made?

The last two digits of your model number indicate the production year. Check positions 12-13:

• NS-55F301NA21 = 2021 model

• NS-55F301NA23 = 2023 model

• NS-55F301NA25 = 2025 model

Year codes range from 12 (2012) through 26 (2026) for current production. Note that TVs are often manufactured in Q4 of the previous year—a "25" model may have been produced in late 2024.

What remote works with my Insignia Fire TV?

For Fire TV models from 2019 to present (year codes 19-26 with "F" in position 6), the NS-RCFNA-21 replacement remote provides full compatibility including Alexa voice control. This remote also works with Toshiba and Pioneer Fire TV Edition televisions.

Alternative options:

• Amazon Fire TV app (free smartphone app works as complete remote)

• Amazon Alexa Voice Remote (3rd Generation)

• Universal remotes with codes 12049, 11780, 11564, or 10842

Who makes Insignia TVs?

Best Buy owns the Insignia brand and designs product specifications, but outsources manufacturing to contract electronics companies. Hisense produces the majority of Insignia televisions—the "NA" manufacturer code in most model numbers confirms this. Other manufacturers including TCL may produce specific models or regional variations.

Components come from various suppliers including Samsung Display and LG Display for panels, and MediaTek for processing chips.

How long is the Insignia TV warranty?

Insignia TVs include a one-year limited manufacturer warranty covering defects in materials and workmanship. The warranty period begins from your purchase date (keep your receipt as proof).

Coverage includes manufacturing defects and component failures under normal use. It excludes accidental damage, pixel defects below threshold (3 clustered or 5 total), power surge damage, and commercial use.

Extended coverage is available through Best Buy's Geek Squad Protection Plans, offering 3-year or 5-year terms with additional benefits including accidental damage coverage.
