Question about RCA P52937 52" Rear Projection Television
The remote control also quit controling the tv.
I know the set well and would like to help---FIRST THING IS DISCONNECT THE POWER TO THE SET---a few minutes will be enough.
Plug set back and a good chance it will have returned to normal
If not let me know and let me know if on the front of the cabinet it has the "GUIDE PLUS" LOGO.

You are going to have to check all of the small tact switches behind the push buttons in the front of the TV set. In the past, someone may have cleaned the picture tube and the liquid dripped down onto the switches and corroded them, or one is stuck closed or the remote sensor is bad. The best way to test this would be to replace the entire switch panel in the front of the TV set. Good Luck

Verify that you don't have a stuck channel up button on the panel. Next check the solder connections on the IR receiver (3 pins). Also check the +5 supply for excessive ripple. Any of these can cause odd behavior. Let me know how you make out.

Out of 30 years in the repair field, I have seen this problem maybe 4 times. Once was a stuck button on the keypad of the tv. The other time was a second remote control with a book sitting on it and it would turn the tv on and off when someone would move something on the coffee table, another time was a bad solder connections on the microprocessor on the keypad circuit board and the last time was from a humorous neighbor in an apartment complex who thought he was funny who had an all in one remote control programmed for his neighbor's tv set.

The front controls are called Tac Switches. They have a tendency of becoming corroded and sending erroneous commands to the micro. You can disconnect the lead coming from the control panel to the chassis and see if it quits. If it does, that answers your question. If you decide to replace them all, try Encompassparts.com

MABYE THE BUTTON IS STUCK. TRY UNPLUGGING THE FRONT BUTTON ASSEMBLY WIRING HARNESS AND USE THE REMOTE.
