Question about RCA P52926 52" Rear Projection Television
I have a 52 inch RCA projection tv. Sometimes the tv will not turn on and if I leave it unplugged from a while and then plug it back it, it will come on. After the tv is on for a while, it will start to roll thru the channels 02-99. I can't stop this process until I unplug the tv again. Please let me know what to do.
Your set uses the 195 series chasis. The only thing I can think of which would make the channels scroll by themselves is a contaminated PC board and pushbuttons behind the buttons on the front of the set. This is usually the case when spray cleaner or some other fluid is sprayed or spilled on the screen, and it drips down onto that board. To prove this, remove the back cover and on the top of the main chassis, where the top of the picture tubes are, is a small PC board with the remote reciever and a couple of jacks. The smaller jack is for the speakers and the larger jack is for the front panel PC board. Unplug the larger connector which goes up to the front PC board and then turn the set on with the remote. If the set works normally, the front PC board will have to be removed and cleaned or repaired (or just leave the jack unplugged and work the TV from the remote only). If you do not have any experience working inside projection sets then allow a qualified tech to handle it for you.
