Remove the three screws from the main chassis than release up the two chassis lock on the right and left hand side than slide out you might have to move the DM module on the left side to get the chassis out.

Mitusbishi Model ws-65819 color convergence repair. How does one go about fixing it?


The two stk-392=570 chips need to both be replaced===they are along with the rest of the circuit on the middle board.

My 55" WS Mitsubishi projection


The convergence is out, and the convergence ICs' would have to be canged on convergence board, and you are looking a a repair bill between 300-400, and if it was mine for the year that it is I would not lay any money into it, Just buy a new LCD, take care.

9 year old TV...red shadowing. Is a bulb out?


No,this tv don't have a projection bulb inside,it used CRTS tubes like R,G,B guns technology.The tv problems u are having it is call convergence problems,it is dead.The tv convergence board it dead or dying that why tv have R,G,B colors lines misalignments,have colors shadows picture or have 3D pictures look alike.The tv convergence board must require changes like 2 STK convergence ICS and some or all of it resistors too.To fix the tv convergence board to solved the tv picture convergence problems.The tvs Shops will cost u like $300-350 for parts and labors.

Red.yellow and green colors do not align. What is wrong? Isd it something I can fix?


If your picture has a 3D effect and you try to align with the cross hatches, then you have a convergence issue. I usually change both convergence IC's and any resistors that are open in the circuit. It requires unsoldering and soldering in the new convergence IC's. To locate the IC's, you can identify them as two side by side black chips about 3 inches by 2 inches with 18 pins each soldered to the board and on a metal heat sink. The numbers on them are identical and start as STK 392- 120 or 110. It is quite a job even for a skilled tv tech. After installing them and any resistor that is open, you will be able to align the cross hatches.

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.

The red part of the picture is curved and separated from the other colors.


If you go into the customer menu and select convergence--then advanced(there will be instructions on screen) and red or blue are skewed and will not adjust--you have a convergence circuit problem.

The WS-55511 you have indicated uses a large single IC chip for this---a STK-393-110. SHOPS get 300 or more for this but you can buy all the parts needed for under 30 dollars--one seller I use on Ebay has that chip for 12 dollars.

If you confirm you have a convergence problem and want to try to fix it yourself---I have START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS MODEL.

They tell you everything you will need and how to do it.

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.

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,
