Question about RCA P46921 46" Rear Projection Television
The RCA Set does not use convergence IC's Im afraid. It uses discreet push pull type transistor array just like a low power audio amp. there are 6 NPN and 6 PNP type transistors. they also use preamp to drive these transistors. Then to make life a bit more difficult, RCA uses a separate power supply board for the convergence alone. These should be checked both at the same time. The boards most likely are not available, so you will need to have the boards rebuilt at PTS corp.com, or Tristatemodule.com. Good Luck
