2. Full-array LED: LEDs spread across the entire back of the screen

3. Direct-lit LED: Similar to full-array, but with fewer LEDs and no local dimming

4. ULED: Hisense's proprietary backlighting technology for enhanced picture quality

5. Dual-cell LED: Advanced technology using two LCD layers for improved contrast

Diagnosing Backlight Problems

Accurately diagnosing the backlight issue is crucial for determining the appropriate fix. Here are some methods to help you identify the problem:

Visual Inspection Techniques

A thorough visual inspection can reveal a lot about your TV's backlight condition:

1. Turn on the TV and observe the screen closely

2. Look for any dark spots or uneven lighting

3. Check for any visible damage to the screen

4. Inspect the edges of the TV for light leakage

5. Examine the back of the TV for any signs of overheating

Using the Flashlight Test

The flashlight test is a simple but effective way to determine if your TV's backlight is the issue:

1. Turn on the TV and play some content

2. Shine a bright flashlight close to the screen

3. Look closely to see if you can make out the image

4. If you can see a faint image, the backlight is likely the problem

5. If no image is visible, the issue may be with other components

Checking for Sound Without Picture

If you can hear sound but can't see any picture, it's a strong indicator of a backlight problem:

1. Turn on the TV and try to play some content

2. Listen carefully for any audio output

3. Try adjusting the volume to confirm sound is working

4. Attempt to navigate menus using the remote (listen for menu sounds)

5. If you hear everything normally but see no image, it's likely a backlight issue

Identifying Flickering or Dimming Issues

Flickering or dimming can indicate problems with the backlight or power supply:

1. Observe the TV screen for any inconsistent brightness

2. Look for rapid on/off flickering of the entire screen

3. Check if the screen dims unexpectedly during use

4. See if the flickering/dimming gets worse over time

5. Note any patterns in when the flickering or dimming occurs

Differentiating Between Backlight and Other Display Problems

It's important to distinguish backlight issues from other display problems:

1. Check if the issue affects the entire screen (likely backlight) or just portions (possibly LCD)

2. Look for color distortions, which are more likely LCD than backlight issues

3. See if the problem persists across different inputs and content types

4. Determine if the issue is constant or only occurs with certain images

5. Consider whether recent events (power surge, physical damage) might point to a specific cause
