Repair guides
What’s wrong with your TV — explained by people who open them
Short, honest guides to the faults we diagnose most. What causes each symptom, what you can safely check yourself, what the repair really costs — and when a $25 diagnostic saves you from a $95 house call.
TV won't turn on
6 minThe causes ranked from free fixes to board failures — the outlet checks, the power reset, and the sound test that narrows it in ten seconds.
Vertical lines on the screen
6 minThe menu test that halves the problem list, the T-Con board story, and the line between a $100 repair and a panel write-off.
TV has sound but no picture
5 minThe flashlight test that confirms a backlight failure in ten seconds — the most misdiagnosed fault in the trade, and usually the cheapest to fix.
Reading about it only narrows the list. A diagnostic with photos of your actual TV names the part and the price.
