Sounds like your color guns are out of alignment and need adjusting. its a cheap fix with a tv tech but i wouldnt recommend doing it yourself. plus, a visit from a tech can tell you if there is anything else wrong/about to b wrong

My RCA projection TV - the picture only shows red green and yellow and the picture is distorted almost concaved. It overlaps and nothing is clear. All 3 bulbs seem to be working. No idea what is wrong.


Sounds like convergence problems. This TV may not have the standard "STK.." modules. These sets are bad to lose voltage feeding the convergence amplifiers.

Covergence problem


your set has indications of several problems. red green and blue. indcate convegence issue. the fact that the picture is concave is a indication of totall loss of covergence power supply. the convegence menu missing idicate loss of some voltages from what know as the flyback.AND SHUTDOWN. indicate further problems. generally when convergence fails ..not always the set wont shut down. it could be a simple issue but further trobleshooting would have to occur to narrow it down.

My RCA Tv has a concave picture!!!


Convergence problems. FIrst try going into customer setup and seeing if convergence options are there and if adjustments can be made. unfortunately when the picture is bowed like that it idicates a complete loss of convergence which idicates one of three boards have gone bad.
