Riddled TV Repair Forum

This TV was only 9 months old when this started, It turns itself on and off while coming up with different screens everytime like notepad then starts scanning channels, turns off on on continuously. I tried every service code I could find on RCA but I don't think it would help anyway as it turns On & Off so frequently you don't have time to push any buttons. I can turn it off & On with both manual button and RC but it only takes over on its own each time. It actually shows a picture when cable is hooked up when it turns On, but always turns back off and On then goes nuts!! Is it possible that this is the (possibly corrupt) Eprom chip? or another flash chip on the board? Need help to figure this out......Thanks in advance.

I know this many sound kind of a funny question, but do you have children?? You are describing a stuck button. I have seen this kind of failure mode and most of the time it is due to peanut butter and Jelly fingers.

A stuck button will lock you out of all functions of the tv set. Even the remote will not work correctly.
Carefully check and see if their is a small amount of movement when the buttons are pushed with your ear close to see if there is a faint click. If there is one of the buttons that does not move or you cannot hear the click you most likely have a stuck button.
There are no service bullitons relating to this on the RCA Technical Website.

Hope this helps

Thanks for the reply Jesse,

The first thing I did was check the buttons for sticky stuff like you said but I beleive it goes deeper.

I'll keep researching until I find something.

Thanks, Danny
