Question about Mitsubishi WS-55511 55" Rear Projection Television

1 Answer

My 2002 Mitsubishi WS-55511 all of a sudden looks like it needs to be degaussed. The blue will not align using Advanced Convergence. The farther you move above and below horizontal center line the greater the arc that the blue is out of alignment. What is the typical cause and repair?

The WS-55511 uses a single STK-393-110 convergence IC.

You need to replace it and check all the 3.9 ohm blue resistors in front of it.

You can buy the part on Ebay for about 14 dollars plus shipping.

If you are able to do this repair yourself you can save a lot of money as most shops charge 300-400 for this type of repair. Several sites on the internet offer instructions on how to do this repair--I have my own instructions but I am not permitted to give My email here.

If you cannot do this repair--shop around in your area and if they say "it has to go to the shop" keep looking as any good tech can do this repair right in your home in about one hour---I know as I have done hundreds of them here.

If you have ANY questions or need assistance reply to this posting here and I will try to help you--I am here to help people.

REGARDS, SD TECH

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.

I have a 55 inch rear projection mitsubishi tv. it recently has started showing what looks to be white spots when viewed at a distance on a dark screen. when you look at it closely it actually is red green...


It is called Convergence. You have three CRTs. Red, blue, Green. When they are not aligned, you will see the individual colors. See if you can do some alignment in the users menu. Look for Converge or Convergence in the menu. Either under video or setup.

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.

If this information helped you rate this solution as I do this here for free. If you want the instructions I can post them here.

PROJECTION TV COLORS DISTORTED


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.
