Derek Whitfield is the setup & repair editor at Tech Junctions. He's the byline on every "how to mount", "how to connect", "won't turn on", and "no signal" article on the site, because he does this work for real - fourteen years installing residential A/V equipment across the US Mid-Atlantic, certified by the International Society of Certified Electronics Technicians (ISCET), and currently maintaining an active residential-installation business that gives him a steady stream of real customer problems to test his troubleshooting steps against. When a power board fails on a Samsung TV, Derek's article describes the actual fix he'd run, including the multimeter test he'd do before recommending a $200 part. He owns the HDMI/ARC/eARC pillar because cable confusion is the single most common reason readers email a corrections request. He lives in the US Mid-Atlantic.
