They are solder in parts. The fuse is a 400 milliamp, and you can get it from radio shack. The Diode crosses to a nte 558, and can be purchased offline, or possibly at radio shack.

Is there a way that anyone can tell me where the fuse panel is on a RCA Model #: R52WH74 television?


There is one fuse on the AC filter board which is where the power cord is located. Just trace the power cord back to where it plugs into the circuit board on the right side when looking in the rear you will see the fuse located right next to where the cord plugs in on that board.

Replace the deflection board you have the same deflection board as the R52WH74 model or the PSB-260 deflection board. You can get replacement deflection boards from www.tvrepairworld.com and also on ebay.

Your convergence amplifier has failed.
There are a few things that usually cause that in that particular chassis design, the most likely one being that you have lost part of the power supply to the convergence amplifier power supply board.
You may be able to repair it yourself if you're good at soldering, and dis-assembly / re-assembly.
Look for a 400ma fuse that's opened near the FBT, and re-solder all the connections in that area. Also check to see if any diodes have shorted around it too.
Good luck.

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.

Dear Video77301,
Good Day greetings from me. Please verify or be specific about blinks. 1 LED blink then 9 blink code. I this the number of times ? or 1 and 9 appear? If so pls. check the error coding in your Users' Manual, it is found in the Troubleshooting Pages..Then give us the instruction of each number.... If your set is newer,then you have your warranty, call the store where you purchased. This kind of problem might be in the Stand By circuits , an IC or Microcomputer chip is defective....

BEST RGRDs,
Eriez

Rca r52wh74 - no auto convergance


On this particular model when your convergence is out of alignment, and the auto convergence is suddenly missing from the TV's menu all together, there is a easy fix.

Diode on Main Power supply, Location dl321 and fuse at Location fl231.

This problem has a high failure rate.
