Please help us as well in Florida...We've had the 27" TV for only two and a half years and now the set is turning off and on.
My observations since this began a week ago is that the TV warms up for about an hour before turning itself off and on (nobody is touching the remote, no power outages or power-surges account for the number of times it turns itself off).
We don't leave the TV unplugged @ night and during the day when we're at work, but when it gets caught in the glitch, we've simply unplugged it until the next day, thinking it its caught in the "built-in relay" problem that Tech Support for Thomson/RCA told us might be the cause of the same problem in the HDTV sets.
One question - could this issue be related to things attached to the TV, like a Wii and DVD/VCR combo? Just a suggestion....

Re: TV turns on & off
Exterior equipment attached to a standard tv cannot cause the set to switch on/off by itself.
I think you may have a power supply fault or else loose solder connections on the board, hence the "warming up" intro before the fault shows itself.
My suggestion would be a service technician if you are not familiar with electronics or TV's. Regards, JUS004

top half missing is in vertical circuit of set---if it is a 27 inch and this old consider retiring it and replacing----other option is consider having a shop repair it--a rough guess would be as high as 150 dollars parts and labor is possible for your problems.
keep tv off.
it will only get wors
if sumon dosent work on it soon
the problem you are having in the vertical section of the tv
hav a repairman resolider all conection on the vertical IC and check the serounding componets for falts.
PS the repair takes me about 15 min.
The eeprom is bad. It holds memory for the micro...it is the micro's ram card so to speak. OR, you have horizontal problems that RCA's are know to have. Google your sets model or chassis # and the words "dead set". You will get plenty of info to help you.Good luck!!
I am by no means an expert but i have the same type of TV and have a similiar problem, first I thought it might be a heat-induced effect so I vacuumed the interior but no joy--then I carefully inspected the main board and found two components that looked melted. So I would suggest you vaccum the interior and then inspect. But be careful as I found one capacitor on the board that still had a charge after 3 days of the set being turned off, you might want to verify things with a multimeter before poking around.
If the screen won't come on then the diagnostic will never show. The 4 blinks is an error code. If the set is older than 12 years then it doesn't owe you anything, you got your money's worth out of it. Average life of any tv from that genre is 8-12 years. It's time for a new set, or take it in for an expensive repair ( pending parts availability).
No, the tube is not bad. There are a couple of very small surface mount components mounted by the main microprocessor that could be causing what you are seeing. They are very small and quite hard to unsolder and replace without losing them. The set should be serviced by a qualified tech familiar with the new RCA chassis.
