PCB for a 52" RCA Rear Projection

I have a RCA 52" rear projection tv #p52720BA. The buttons that allow the channel selection as well as volume do not work.
There is a PCB behind the cover. I am thinking this is the problem. Is this part available anywhere and does this seem like a possible solution. The power on and off button is the only one that works

Rca hdtv channel changed by mistake

RCA channel setup and selection is not easy to understand. You may try to add channel 3 on the add/remove channel section. If that doesn't work try pressing the input button. Good Luck.

Rca 52" rear projection tv (P52926) volume control LOCKED!!!

This can be a tricky one, I would check the 5 and 3.4 volt lines first with a DVM (analog meter will not due) then with a scope to see what the voltages are and what they look like. A bad cap on the rail for the e-prom can cause this or the eeprom may be bad, this also happens. It might be best to contact a scv. co. as you can a lot more problems in that area if your not familiar with it.

Yes. Its probably a stuck button on the TV's front panel. Try pushing or wiggling each button on the panel. It could be the channel up/down buttons or volume up/down, menu, etc.

When there is a button that is making slight contact, it keeps the microprocessor busy attending to the command its erroneously receiving from the offending button and may not allow other functions to work when this occurs.

It doesn't matter which button is stuck, any of the symptoms you describe can happen.
