I'd like to learn how to repair TV's and I'm having difficulty finding a site or sites that provide learning material to diagnose a TV. Such as if the TV turns on but has black bars or colored bars running down the length of it, is it the signal board(s) or is the screen itself faulty? If the TV doesn't turn on is it the PS board or is the TV not powering up because the main board is dead and the PS board is not firing up to prevent more damage?
I want to be able to work on TV's and learning more about diagnosing their issues with flow charts or something would be fantastic. Thanks all!!
