If you can not adjust the convergence, then you need to change the convergence IC's The number of the IC is on the chip. There maybe one or two IC chips. I think there are about 12 to 15 pins or so, and will be mounted to a heat sink. There maybe surrounding resistors that need to be replaced too. I hope this is helpful.

Good morning, I am in the moving business and have a customer that wants me to move their large TV Mitsubishi medallion tv. She thinks is comes apart in two peices for easy moving and I need instructions...


If the model is a WS-65809 that sey doesnt come apart. Actually very few rear projection TVs can be seperated Some RCA TVs can be disassembled to several pieces. Also I would let customer know that because a CRT TV has three CRTs that are aligned to each other , Moving the TV will cause the convergence to be adjusted. Based on model it can be just pressing the auto convergence option with the remote, But older rear projection TVs (2003 and older) have been known to blow ICs after a move when trying to reset the convergence. The ICs weaken over age and they can blow anytime the convergence adjustment feature is used, so its always a good thing to let someone know that even if very careful when being moved there set may develop convergence issues after a move because its a 3 CRT rear projection TV

Mitsubishi WS55859, was getting 2 and 2 blink, replaced the pico fuses and convergence chip - 3 times, each fix worked better than the next but evenually failed - now have it working, trying to adjust...


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,Pioneer 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

Can't adjust convergence


This possibly bad solder conections and/or defective Convergence IC's. I personally would pull the board check and solder any suspicious solder connections AND replace the IC's. Less Labor saves the customer money as the IC's can be damaged and on the verge of failure with this sort of problem.

Cannot adjust convergence on Mitsubishi RPTV


as long as there is no bowing in the picture and the color does not want to move then there is probably just a bad resistor on the convergence IC that controls the color alignment , thus the resistors would have to be tested to find the low valued resistor on the IC

Mitsubishi WS 55711 convergence problem only with some inputs


Projection TV2_bing.gif sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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

Note: If you TV has as flash2_bing.gif focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

if the red line is blurry and you have adjusted the screen focus control and does not work then you prob have a bad red CRT or bad red CRT fluid.........
