Your initial problem was the fuse blowing. this is usually caused by bad solder connections on fly back transformer. resolder to solve blown fuse for convergence problem. now for no power check horizontal-output transistor for short. if unit tries to cycle off&on fly back is defective. if no start-up, check capacior in 6v-line center of deflection module in-between heat sink, the top will be raised up . 2200uf/25v replace mch

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.

RCA R52WH74 Convergence Problem


Yes i replace that fluse fl231 all the time at the shop. at least two aweek. and the first few i replaced did the same thing. I would send it back to customer and i would get a call that the set had malfuctioned again and convergence gone. It was determined the reason this fuse blows is bad conections on the flyback transformer. The flyback is the big black component with the red wire coming out of the top. if you examine the connections on this component there will more than likely be a ring in the solder. this is caused by the manufacturing process known as LEAD-free solder. THis cause oscillations in that cuicit. like turning it of and on really fast. this is a very small fuse and cant stand up to this. so when you replace this fuse just simply RESolder these connections apply a little amount of solder to these connection. i am confident this will fix your problem.

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.

Full sound not working


I had the same problem and also traced it back to two of the four 7-amp fuses were blown. I replaced the fuses, but they immediately blew again. I used higher capacity fuses (10 amp) to see how bad the problem was and those blew. Testing the problem a third time with the speakers disconnected yielded the same results.
There's an internal short in the system.
The solution? Don't buy RCA again.
