Question about Mitsubishi WS-55809 55" Rear Projection Television

WS-55809 - Video pinched in center, distorted, yellow/blue/red glow

I've read a few things here about this convergence issue. Although my problem doesn't quite seem the same. I can go in the convergence menu for red or blue and adjust them to distort or clear up the white cross-hair. The center of my screen (where that cross-hair is) is perfectly fine so adjustment is easy and I can see that it does indeed work. I have even used the reset convergence option. My problem is that I have a pinching from the top and bottom center toward the middle (video extends to all corners though). I don't know how to explain this and wish I had an option to post an image of what I see. Basically what I have is video that extends to all corners, but the top and bottom center is pinched in toward the center of the screen (like a rainbow?). There are red, blue and yellow lines surrounding the distorted images. Text (like the menu) makes this very easy to see as there is an outline (ghosts if you will) of these other colors around the text and the text or lines are curved toward the center of the screen. This of course causes a very distroted picture. The center of the screen (left to right about 3" in height) is perfectly clear and color is just fine without any distortion that I can see. Is this a convergence problem too? This TV was never that great and I wish I hadn't purchased it. I'm back to watching my 15 year old Sony which has a better picture and is obviously more reliable. Thanks for you help!

Re: WS-55809 - Video pinched in center, distorted,...

This doesn't sound like a programming issue. I had a very similar problem about 6 months ago and I fixed problem. I had cold solder joint on the video power board. It was the board in the middle. The power supply was to the right. The video board had a driver with a bunch of legs. About 7 solder joint where cold or loose. I solder the board and my mitsu wide screen was fixed. Hope this helps.

On my HD1080 Mitsubishi projection flat screen 55809 the picture is bowed on top and bottem and it look as if the projectors themselves are offset, but the picture is clearer as you come toward the center....

It could be one of two things: Either a bad solder joint or convergence IC failure.

Convergence IC failure is very common. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.

Note if one STK chip fails, you replace both regardless

Ws 55809 convergence

Projection TV sets have two very common problems listed below.

Problem #1) Convergence

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,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*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
