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.

I had to replace a fuse for the power supply and know the picture is blurry and bowed

Your convergence power supply is propably not working. The convergence supply board is mounted above the mainboard and has AC 110V supplied to it from the main PCB. That's probably why the fuse blew.Rca Has abulletin regarding replacing two diodes CR19710 and CR19713 on convergence power board.

There are three main reasons that convergence can still be inoperable after replacing the convergence amps. One, when the amps failed they blew the fuses protecting the power supply from shorts. Two, when the amps failed the yoke return biasing resistors burned open. And Three the Digital Convergence Unit has failed. Once things have gotten to this point it is usually time to have a professional have a look at the set.

HD52W59 Convergence problem

DId you solder the flyback transformer connections..... This is the main reason these fuses fail. THe flyback is the big black component next to the fuse. poor solder connection cause oscillations.. this fuse is only .4 amps whish dosent stand up to that well.. resolder these pins on the flyback.... the first time i replaced this fuse i failed to solder played well for 2 days then came back blown again

RCA projector blew 5 amp fuse off line in when fuse was replaced picture came up with smaller picture on screen and convergence way out.

whats the model number and what was the fuse number that blew/ was it FL231 the fuse in the middle? If so you need a convergence power supply board.
