Picture on my WT-46809 not centered

How do I adjust the centering (alignment) of the picture on my screen. I recently had the convergence chips replaced. The convergence is fine, but the picture is off center to the right.

Can I diagonally adjust (clockwise/counterclockwise) my Mitsubishi DLP TV? The picture is off center

You need to align the optics mechanically. If you changed the dlp chip and its not centered then the chip is not shimmed properly or the reflection mirror behind the lens needs adjustment. You should get a service manual for that chassis and follow the directions. there may be an electronic method but I am not aware of one.

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the's something else..don't know you?

Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here

The TV image is bowed at the top/bottom and sides, almost 3D like.

Projection sets have two very common problems outlined below.

The first common problem is 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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.

You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

Convergence on kdp-65ws550

Good Day, s_d_duncan;

The board for this 2001 Model is no longer available. Now, if you can solder, you can repair yourself. The parts you will need are two STK 392-570 (HIC), convergence IC's, part number 270P150010.

If you can't replace yourself, please call an authorized service center to give an estimate....

Good Luck, big IRISH.

Good Day y'all;
When the is picture being intermittent and bowing then the most common problem is that the convergence circuit has failed or is failing. If you don't get fixed, the will go DOA soon.
