Question about Mitsubishi WS-55511 55" Rear Projection Television

1 Answer

Color out of convergence.

Suddenly, while watching one day, the color went out of alignment and worse. Lots of greens, and a arc across the top corner of the screen. I'd guess one of the rear projectors dropped out of alignment or something, but convergence is no help.

    I have the same exact problem
    the TV worked fine this morning and this afternoon, the BLUE is out of convergence and I have a blue arc from the top down and another from the bottom up and the convergence fixer on the remote is no help at all

    Mine acted the same way, this afternoon the blue convergence went screwy. I tried to realign the blue using the advanced utility screen but no luck.

    Irish, is replacing the convergence IC difficult or expensive? We got a new board a few months ago - right before our warranty expired, so I need to decide whether to try and fix it myself, get it services, or start looking for another one. Thanks!

    blue lens misaligned while watching tv. I can move the lens up and down but not left to right.

    I have the same problem. I have had the convergence IC replaced twice since owning it. I purchased the TV in Sept 2003 and have had a repair person out 4 times for issues, twice for the IC. Now it's out of warrenty so I'm going to fix it myself. I checked this site for information on parts and the part listed in this solution was mislabled from the "complete part list" provided by this site.



    The correct part number is: STK393-110

There is a problem with one or possibly both of your convergence amplifier IC's. They both handle some of the green convergence. It should not be extremely costly to have repaired. Do have a technician check it out. Convergence adjustments are tricky. Thanks for using fixya.

Green color seperation multiple images convergence will not fix


Your TV most likely a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

0667c5f.pngSOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Hitachi 53uwx10b Convergence


The grid (called an overlay) is put in place to fine-tune one of the colors, usually green. Once one color is adjusted perfectly, the other 2 colors are adjusted to match the first color. For example, if the convergence data is completely erased, the tech will set up the overlay and align the green using to the overlay, and then align the red to the green and then the blue to the green. If the alignment is being done after replacing the convergence IC's because one or 2 colors are slightly off in the corners, the green is usually very close to perfect and the use of the overlay is not absolutely necessary. It is pretty easy to align one color using the outer edges of the screen itself. If you do need the overlay it can be purchased from any Hitachi parts distributor such as Herman Panson, Fox or Union Electronics.

Sudden discoloration, ghosting, bowed horizontal lines in top and bottom of picture


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
