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?

NGL I usually only do component level repairs on the power boards (or in the case of appliances most of the components are easy to find docs for and are much larger) but I usually find stuff by poking around with my multimeter or looking for obviously blown things. But my experience is more from the realm of appliance repair (and all from experimenting).

Testing capacitors can be done (and if they're big enough) something I'll do as well. I ain't gonna test capacitors that are smaller that a grain of rice.

There are times though that it's easier to just buy a new board rather than do component level repair.
