    Same problem - very annoying. Its almost like it is overheating but it doesn't feel hot. Could it be the transformer? This does get hot.

This model of television seems to have a thermal problem (design issue) where IC U14 gets too hot and shuts down. It can be fixed, but it requires opening the set and soldering. What needs to be done is to add a diode (3 Amp, any Voltage) in series with Coil L18. This fixed 2 sets that I have. Adding heat-sinking alone didn't work. You can confirm this problem by running the set somewhere cold and noting that it takes much longer to shutdown or doesn't shutdown at all.

No,it sounds like a power board failure,look for swollen capacitors,check diodes,and transistors with a multimeter,transistors that read 0 are considered shorted,research them before you just dive into this set though.

I would also keep in mind the small signal board,that may cause it to shut off as well if there's too much current going where it shouldnt be going as a circuit protection

Quite possibly one of the heat sinks has come loose or a power supply cooling fan has failed.
Have you tried blowing it out using canned air?

I put heat-sinks on U14 and the regulator above it and the TV has been running fine all day. Always shut off after 14-30 minutes before. Heatsinks were just 1/2" x 1" metal strips with silicon thermal compound that I taped up to hold in place to temporarily test, as it is obviously a heat related problem.

If you try it and it works for you, post it here.
