For TVs it’s usually really simple, like internal fuses or blown caps. And a few with bad backlights or mainboards that are dead.
For 2 of them it’s been shorts in the LCD itself which meant I had to block the clock pin from the TCON board for the specific part of the screen with the short. Basically killing a line of pixels to get the TV working again. In general if the TV is 4k and smaller than like 45 inches you’ll never see it unless you look for it.
That’s a super involved fix (involving A LOT of trial and error to find the right pin) but it keeps it out of a landfill.
In general fixing a TV is always cost effective unless the actual LCD has physical damage.
hey, I’m getting into this kind of repair. I have good soldering skills and am great at taking things apart, but do you have any tips on how to find the fault? even it’s just a blow capacitor, what am I looking for?
