I HAVE A MITSUBISHI 55 INCH WS55511 REAR PROJ TV, WENT OUT OTHER NIGHT, REPAIR MAN WANTS OVER 400.00 TO REPLACE CONVERGENCE CIRCUIT, WHEN i DID TEST IT HAD THE GREEN LIGHT BLINK 2X THEN 2X WAS TOLD ONLINE IT WAS PICO FUSES POSSIBLY, NOW REPAIR MAN SAYS CONVERGENCE CIRCUIT REPLACE OR REPAIR? aNYONE KNOW ANYTHING ABOUT THIS ISSUE? CAN I FIX IT MYSELF, IF SOMEONE CAN EMAIL ME [email protected] THANAKS

Thats the code for a short. Which is almost always caused by the Convergence circuit. You can get the WS55511 Convergence repair kit from www.tvrepairworld.com which contains the parts and the CD with instructions
Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.
Thats an easy fix. The capacitors on the DM are known to fail . You can get the WS48511 - WS65511 DM repair kit at the following link which contains the replacement capacitors and the instructions on how to do the repair on CD which also contains the Service Manual

You can try to enter the menu and go to advanced setting and adjust the convergence. Push audio to go to advanced convergence and do the multipoint convergence to re-align the colors. If this doesn't solve, you may need to do a hardware repair.. all projections of this type will need a convergence IC repair sometime during their lifetime.
After further inspection, I believe that you have a blown convergence IC. Most posts point for two IC's. I only have one. STK393-110. There are 12 - 3.9ohm 2w resistors around it . I think they may be bad as well. The 2 Pico fuses feeding that circuit (+24/-24) may be open also. So, with that said...... Think we have the problem cornered?
