It has curved screen and double letters


You have a defective deflection board. Normally there is a three brown fuses next to the fly-back transormer and one of then must me open for over current. You need to replace the fuse and resoldered all the Fly-back transformer pins...Good Luck

I can't find auto converge choice in menu of rca 52" rear projection tv.model # R 52 WH 74.


You have 3 pico fuses by your fly-back transformer. One of them blew that controls your convergence circuit. Your TV now thinks that it is a Basic CRT set with 1 tube. Find the bad fuse and replace with a 1/2 amp pico fuse, and re-solder all the pins of your fly-back transformer. Your menu should have the convergence option again.

Resolder the connections on the high voltage transformer. There are 3 fuses mounted to the right of this transformer. They look like 3 brown boxes. Replace the center one if its open. ABOUT 1/2 AMP pc mount fuse pico fuse will do. Common failur eon this tv.

Colors seperating and Screen bowing


The convergence circuit is not working. There are bad solder connections on the sweep board and a small fuse is open. this is not easily done yourself unless you have a technical background but an RCA tech can fix this easily.
