Rob, possible bad relay, bad caps etc. What have you checked? Have you opened the back and take a look at the power board?

What happens when you pull the power altogether (unplug)?

It powers up after plugging it back to power source. It reads the remote and responds to (on tv buttons). BUT after awhile the problem comes back. I cannot figure out what the source of the problem is.

I agree with oldturkey (and I am never going to catch up to him!): post pictures. That said, works and then eventually fails smells like a failed capacitor, or bad / cracked solder joint or trace. Rationale: the components that are time or heat sensitivity tend to be those.

In the meantime, you have also effectively found a work-around: put a switch (like a power bar) and turn it on before you want to use it. Not a bad idea from a power-savings and safety perspective, although less convenient.

Rob, check the power board. It should look similar than the one in the image. Check for anything odd looking. Post some images of your board with your question. Use this guide to help you with that. Just make sure that yuor set is disconnected and that you don't poke around the components with your fingers, Capacitors will hold a charge, even when the set is unplugged, and may giving you a shocking experience.

Assumming its not a universal remote that has forgot the code or week Battary check the standby voltage on main logic and look at the plugs on that board there marked what voltage they should have if there all correct then its your main logic ( I'm betting that's what it is )
