RCA R52WH74 Convergence Problem

Hi:

Thanks for the clarification. I went ahead and ordered a new convergence power supply board from the http://servicemanuals.vstore.ca site which you provided me. I will try swapping out this board and replacing the FL231 fuse again to see if the fuse holds this time.

I noticed on my PayPal receipt that the seller e-mail is slinteriors@yahoo.com. Is this you? I was curious as to your business...do you buy/sell parts for the repair questions you recommend solutions for? Or are you somehow an RCA authorized service technician? Just curious.

Thanks,
Don

No my brother and I have been doing television repair since the mid seventies, and when we retired we decided that we would start a business as a way to help the avererage person repair their own sets without having to pay alot of hard earned money for something they could easially do theirselves, that why we give free tech support, 99.9% have easially repaired their sets for less than most shops charge for the estimate.

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.

This is called convergence board failure. try to re calibrate the convergence. if the re calibration fails, this means your convergence board will need to be replaced or, rebuilt.

RCA R52WH74 (ITC222A Chassis)


no the board that has the FL231 on is the ITC222 deflection board. The other board is above the chassis in a seperate frame that runs across the set the convergence power supply is the board on the left above the board where the fL231 is. Yes the ITC222 and ITC222A are the same chassis. As for the service manual that site should have the service manual under the thomson category as the ITC 222 chassis is actually a thomson chassis made for RCA.

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.

Rca d52w19 convergence hell


Did you replace the convergence board or the convergence power supply board? usually one color will be a problem with the convergence board and more than one color means the convergence power supply is the problem. Ebay isnt a good place for boards as you never know if the board is good. You can get the convergence or the convergence power supply boards at the following link along with free shipping and tech support.

Check for voltages going to convergence power supply PCB on connector Bl600. If low or missing, check for bad solder on flyback and pico fuse # Fl231 for open.
