Question about RCA P46922 TV
It looks like the red & green are off centered. There are double images of the colors on the screen? And it looks like there is a "pinch" in the center of the screen. I took the back off and took the mirror out, and it's not anything with those..its in the lights. how do i fix this? Thanks, Dan
Your set uses the 195 series chassis, which has separate components for each of the 6 convergence channels and a separate power supply for the convergence circuits. If all 3 colors have drastically shifted, especially around the edges, then chances are your convergence power supply has stopped working. This is usually caused by the failure of the STK730-010 switching IC. If one of the colors has dramatically shifted by itself then something has stopped working on the convergence board. Sometimes I see CRT coolant leaking onto the convergence board as the cause. In either case this is something that should be repaired and realigned by someone experienced with RCA projection TV convergence circuits.
