RCA Projection P52937SG Continually changes channels

Hi, I took the power supply out and found R14512 colored white from heat.
Do you know where I can get schematics or a service manual? I think the resistor is a 10K, 2W. Any way you can help me would be greatly appreciated!!

P52937sg will not stay on one channel


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.

Your set uses the 195 series chassis, which has separate components for each of the 6 convergence channels and a separate power supply for the convergence circuits. If all 3 colors have drastically shifted, especially around the edges, then chances are your convergence power supply has stopped working. This is usually caused by the failure of the STK730-010 switching IC. If one of the colors has dramatically shifted by itself then something has stopped working on the convergence board. Sometimes I see CRT coolant leaking onto the convergence board as the cause. In either case this is something that should be repaired and realigned by someone experienced with RCA projection TV convergence circuits.

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.

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.
