The tv changes picture format on it's own. The picture also appears jumpy. I have searched for similar problems with rca, but haven't found anything.
Thats caused by the small signal board, which is actually a board known to fail when the aspect changes on its own like that. You can get replacement small signal boards at www.tvrepairworld.com
The easiest way is to take a basic course in basic electronics then repairing a TV is usually just testing voltage supplies based on schematics to pin point the trouble spot. You can get some free training info and help from the website I pasted the link too. Just send them a email indicating your desire to learn TV repair. They will usually help with training materials .
