I have a 2002 RCA P46924, chassis CTC195M26A. Last fall it stopped working and I had to replace the flybact and the HOT. I finally got around to doing it and now it looks great but it intermitently turns off (both audio and video) and on within 1-2 seconds. Sometimes it will try and come back on but turn off again. If it does this three times in a row it will stay off until I power it on.
Did you try looking for cold solder connections to start with?
Anything that is going open or short can cause a set to turn off. You would have to troubleshoot the set during the fault condition to see where the failure is. Start with investigating the power supply, protection circuits, and then on to the scan circuits.
