Hello I have a RCA 60" Rear projection TV (Model# P60812BL) That I just bought yesterday and I am already having problems with it. The T.V. will turn itself off and then back and then sometimes back off again. Sometimes it's within 5 seconds of turning it on initially and other times it will be ok for 5-10 minutes. It seems like as soon as it starts doing it does it every 30 seconds or so (give or take) Any ideas as to what the problem might be. Please help!!! Thanks

What Chassis# CTC..........?

The chassis number is PTK195AC. I hope this helps Thanks

It could be your tuner grounds that need resoldering, also other bad solder joints in the power supply,also could be the flyback transformer going bad,the crt tubes themselfs,try to resolder all over the power board,also go here there are some good tips;
