Check Cr4503 in the vertical circuit for short or leaking. The convergence circuit is most likely fine. Also check for any leaky electrolytic caps in the 500 block. (example) CR4503 will be printed on the PCB as CR503. The vertical circuit is located in the center of the chassis behind the big aluminum heat sink.

Help with RCA projection TV P46812BL (chasis ptk195AA)

You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

Convergence Power supply board. In the television above the cuircit boards there are two curcit boards that sort of hang above. the one on the right is the convergence amplifer board(has metal fin like heat sinks).. The one on the left is the convergence power board. Since you have options and no control, bowing picture. this would be my first choice. Now it still may have convergence amplier trouble. To get these boards you will have to get the entire model with suffix ext. it will be like d52w20...yx1 yx2 or something like that. in small leter on the model sticker on back
