TV going a little crazy

My LG tv keeps turning on and changing channels at random. The picture is fine and everything is fine except for that. It works properly for a couple of hours but then it starts to change channels on it's own or if I am in an input it flashes "function not available now." If I turn it off and leave it plugged in, it turns itself on at random. If I unplug it and plug it back in, it works for a couple more hours but starts acting up again. I bought a new TV but now i just want this to be my computer monitor through an HDMI input any suggestions? can I take out a board that may be causing the problem and leave in a board solely for making it a computer monitor?

I would suggest you contact LG even if the set is out of warranty there may be a software upgrade for this kind of issue or they may be by model number familiar with the problem.

It is what I call a micro related problem-all sets have a micro processor and when you unplug the set it resets this circuit.

Testimonial: "Thanks. I was trying to avoid sitting on hold and being told I'll have to send it in for repair. Was hoping maybe someone could come up with a quick fix. But I'll probably end up calling here shortly anyways. I don't want the TV to go to waste. "

Why does my 52" RCA randomly go through menu and features and I can't stop it?

That is why you got it for free. Lot worse if you paid for it!
Circuit board responsible for remote operation and menus is fubar.

Channel keeps changing

It sounds like a stuck button or switch. What happens when you hit the channel DOWN, does it still keep scrolling down?
Is this with or without the remote?
Have you tried it with the remote and or the TV?

Let me know whether you are changing the channels with the remote or the buttons on the tv and I can try to give you a couple more suggestions.
