How to reset convergence? on mitsubishi ws 55511, has a shadow colored blue or yellow

There is an option in the user menu on the tv. Using either the remote or control panel on the front of the tv, press MENU then select SETUP. After you choose SETUP go to the 3rd column with the 3 icons. Here you can adjust the red or blue color or reset the convergence back to factory default.

After a few years the set will begin to show increasing problems with the convergence settings. When you can no longer adjust either red or blue horizontally or vertically an IC replacement will be needed. Your set uses (1) SANYO stk393-110 and you want to make sure it's SANYO and not a knock off brand as those usually fail prematurely.

I can't get the convergence on my ws 55511 hdtv to go away. I've tried with the remote. How can I get this corrected?

If the convergence will not adjust you have a convergence circuit problem.

This model uses a single STK-393-110 CONVERGENCE IC 129b244.jpg If you are handy and know how to solder it is a 12 dollar part on EBAY

I have start to finish step by step instructions for this repair in this set.

Most shops will charge 300 or more for this repair.

If you want the instructions let me know and I will post them here for free.

with the original Mitsubishi remote go into the customer menu and to the Convergence; there will be instructions on screen telling you what to do; if either color does not adjust---you have a bad convergence Ic; the WS-55511 uses a single convergence IC-----it is a STK-393-110; I have seen a lot of them bad and intermittantly bad---someone needs to replace and then take the set into the Technical menu and adjust the convergence there(it is accessed with the remote by entering a number code for this model--any tech should know and be able to fix this problem in your home----I do a lot of these sets with this exact problem. Hope this was helpful.

My mitsubish model ws-55511 has colors like im watching a 3-d movie. can anyone give me some help

You have a failure in you Convergence circuit.
Probably a pair of STK-392-570's or a single STK393-110. These are common failures with this model series. I do however stress that the location of screws securing the board to the tray poses trouble getting the board out. I do recommend that a qualified serviceman do the job. You do not want to break the board because it probably is not available anymore through Mitsubishi.
I hope this helps,

Mits 55908 Convergence problem

Good Day, John;
It sounds like the Convergence IC's have poor solder connections, by re-soldering the convergence output IC's should solve your problem. The IC's are large and mounted to large silver "heat sink" with STK 392 # on them. Good Luck, big IRISH.
