On that chassis the only fuse affecting convergence is a 400ma pico fuse near the flyback transformer. If this fuse is open the signal board will never send the "ON" command to the convergence supply so the convergence will be dead.
If the pico isn't open then suspect the amps themselves or possibly an open resistor or two.

The tv have a problems known a convergence picture problems,it is dead.Tv have any colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?Yes,than the tv convergence board it is dead.The tv convergence board must have it components parts replaced like 2 STK convergece ICS and some or all of resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops will cost u like $300-350 for parts and labors.

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.

Sony model kp57ws510 rear projection. convergence problem. convergence button on front of tv does nothing


There are a set of convergece chips that need to be replaced. If they have been replaced and you still have the convergence problem you will need to change ceramic fuses in the power supply or on the board where the STK chips are located

Lost convergece and not on the tv menu


Simple problem to fix for a professional; pretty hard to do yourself. There are bad connections on the flyback transformer and a fuse is open. Where do you live; i'm due for a road trip.

Big Screen problem


What did you put in. convergence amp or convergence power. this is a rca hd52w59? i always ask the question in customer menu under setup can you see the option of convergence. if not this is the fl231 fuse problem. consult the article fl231 under tips and tricks section of my profile. the curved picture is an indication complete loss of convergence power. there is a board that does provide convergece power. The convergence on this set is controled by three diffrent boards. power,amp and the small signal board. the small signal board is the most expensive and most complicated to replace ussally a tech has to replace that.

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

Can not convergence


Check for poor solder connections on both StK392-570 convergence Ics (Mitsubishi p/n # 267p150010) If there are none you may have to replace the amps - but that should restore normal convergence..
