RCA 20f510td The TV will turn on and operate normally for about 5 to 10 mins and then shuts down. All functions seem to work great until it just shuts off, then nothing on the screen, its just as if you turned the set off. Now, I can turn it right back on and it will operate fine for another 5 mins and then shuts down again. Any help/ideas? Thanks in advance.

Sounds like a thermal breakdown of a componet. it could be in the main power supply regulaor supply or even a bad capacitor in the power or sweep supply. In some cases Zener diodes can break down and change values after warm up. In some cases also bad solder connections in the highvoltage section, or the power supply can cause this problem. It is a hard call without being able to look at the set. Just a few leads on where to go first. most likly a combo unit, such as this one , would cost you more then a new one these days. Good Luck PS Please dont forget to rate this thread.

Samsung TXM2796HF Turns off after 45 min to 1 hr

Probably some component in the power supply. Look for a leaking or swollen capacitor. They can change value during operation unlike a diode or transistor that either works or does not work. U might even remove and test all caps in the PS area and replace any one that is questionable regarding its specs.
