The red lights came on. And my TV isn't coming on. And where is the power supply board at. And I don't have no warranty on it so can u please tell me how I get my TV back working and running again.
The power supply board is going to be inside, the easiest way is to just follow the power, from where you plug the power cord in to the first board that gets the incoming AC power, thats the power supply. If the red light comes on thats the standby power, so at least the 3.3v or 5v rail is working, depending on the model it could be one of the two, but the other voltages might not be available when you try and turn it on, bad capacitors is the most likely culprit on the power supply board. The only way to know for sure is check all the voltages, most tv power supply boards will have at least one connector with the voltages that each pin should have labeled on the board, but i have seen some that don't. I usually just look for bulged capacitors, replace those, and check voltages. If that doesn't fix it then it might not be worth fixing, replacement boards will add up fast, and TV's are so cheap now its hardly worth dumping a hundred bucks into repairing one.
