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.

It is a older RCA---confirm model number and year set made if possible---also some of these had a simple problem where channel number would change but channel would not---let me know if here is your problem--if it is this the set has the Guide Plus Logo on the front of the cabinet.

RCA Projection P52937SG Continually changes channels and wont respond to controller


This is an older set but I have two questions:

Is the set actually changing channels up or down or are the number for the channel doing that while set remains on same channel?

Two possible problems, some of these also had the Guide Plus Logo on the front of the set.

If I know which issue you have I can help.

Hi

Replace all tact switches at the control panel... all switches is have bad resistance thats why your system is abnormal!
