Question about Televison & Video

1 Answer

I have an RCA 52'' TV, model number R52WH74. I have replaced the FL231 fuse and re-soldered the flyback as well as some other places on the board who needed it. The picture looks fine, the only issue I have is that the alignment is off slightly to the left. I looked in the menu, and I'm not seeing an option to auto align it. Any suggestions would be greatly appreciated!! Have a great day!

Convergence should be showing on Menu. Hit menu then go to setup you should see it listed their.
Heres How to Enter Service Menu for alinement of
convergence BUT I MUST WARN YOU be very carefull of adjustments in wrong alinement. With TV turned off PRESS and HOLD Both CH- and VOL- release when set comes on Now you should be in Teachician Service Menu there you should be able to Do convergence alinement and set Auto convergence.

Replaced the fl231 fuse tv worked for day now blown again and tv keeps shutting off what do i check now


Resolder the flyback pins as thats what causes the FL231 fuse to blow. Soldering the flyback should solve the issue you may need to replace the fl231 again

Sitting here watch tv and suddenly the picture went warped and discolored. Picture looks like the colors are seperated. blue green and red.


Your TV has convergence chips that need to be replaced by a tech. These keep tour red green and blue lights in sync with one another in order to give you a sharp color picture. When they fail your colors seperate.

R52wh74 already changed 231 fuse still not converging


Did you change DL231 and CL230 with the fl231? Also did you reflow the solder on the flyback and vertical IC? Bad solder is what blows the FL231, but without changin DL231 and CL230 and resoldering the flyback and vertical the fix wont be fully effective.

I have the same tv and just had mine repaired for the same problem just got it back yesterday turned out to be the fl231 fuse blown and the flyback transformer solder points have rings in them. It cost me $211.00 to get it fixed and they said it's common problem and most repair shops should have the part in stock and fix it in a couple of days.

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 R52WM24 52 in. HDTV convergence IC location


the rca itc222 chasis uses no stk the convergence is controled with transistors... the convergence amp board is located above the main signal board(green board)... it can be identified as the one with several heat sink fins on it. FL231 is related to convergence.. there has been a problem with this fuse when it blows the processor doesnt know it is a projection set so it turns it into a regular tube tv. Here at the shop we have found number one reason this fuse blows is poor solder connection on the flyback. So replace the fuse and reflow the solder connection on the flyback and around that area also the horizontal transistor and then see if that doesnt fix the problem.. if you have an more trouble ..... willie@fordtv.com

RCA 52w59 projection fuse fl231


Instead of taking the board out, I just soldered two wires to the old fl231 fuse on the underside. Installed a fuse holder with a half amp fuse. And I re-soldered all of the flyback points. My tv is working like new. thanks for everyone's help.
