Re: RCA TV 27 inch 9 years old
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!!

The tv has lasted ten years which is better than average, I find fixing anything after that time is not cost effective and the likely hood of additional breakdowns is extremely high, because you are dealing with parts that are ten years old. But to address your problem, when you first turn on the tv can you hear high voltage been generated, if yes! you have a video problem, If no! you have a high voltage issue that will involve the high voltage transformer and other parts tied into the horizontal output circuits. A tv technician is recommended to address the situation and I advise an estimate.
I ouldn't find any good news on the web about this,
so i did a bit of research and discovered that it wouldn't cost me much more than the cost of repair if I went to Best Buy and bought a new HD-TV.
Wow ! The prices have really come down !
Now I'm glad that it malfunctioned !
Your TV is being overheated by the location it is placed. try moving it in an airy area and see if the problem still occurs. The turning on and off is a response to overheating sensors in the TV housing and if not rectified it could malfunction and may cause burnout, a possible risk of fire.
I believe you have lost the green channel leaving only the red and blue. It could be an internal connection like a solder joint or connector, or it could be component failure from the CRT to an adjustment pot. Being the set is ten years old it wouldn't be worth spending a lot of money on it. You can buy a 27 inch TV now for almost what a repair would cost. If the picture was very good before this probem you may try to get it fixed cheap. Otherwise it probably wouldn't be worth it.
My 27 inch TV's (A Sony and a Sharp) are pretty old and I would fix them myself if the picture tube was very good.
This may be a very good time to buy considering the discounts being offered. ;-)).
The model you listed, F27650 uses the new ATC113 series chassis, which is only about 3 years old. The ATC113 chassis is not known to have snowy issues, but if yours is then I would suspect that a solder joint is loose in the tuner. If your set is actually around 9 years old, then it might perhaps have the notorious CTC175 - CTC187 series chassis, which went snowy all the time due to cracked solder joints on the shield grounds around the tuner and microprocessor. In either case, some good quality resoldering should cure your trouble. If you have never done fine solder work on PC boards with small surface-mount parts, allow a qualified tech to handle it for you.
You apparently have a high voltage arc.
Possibly the anode lead to your picture tube.
Also the flyback transformer could be arcing.
If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock.
Be careful !!!
