Question about Mitsubishi VS-5059 50" Rear Projection Television

1 Answer

Mitsubishi VS-55609 The Television turns on and displays a picture. The problem is the Blue Convergence will not vertically align, horizontally will align, but not vertically. From the previous post it appears that the STK amplifier has gone out and needs replacement. I would like to change out the IC with a replacement with a higher current/voltage value to last longer and the safety precautions in replacing this driver. I have seen the driver ( the television uses only one) and it looks like the PCB will have to slide out and placed in horizontal position. Can you give me places where to purchase the IC, Schematics/service manual steps or can you give me step by step instructions on what components need to be neutralized before working on the set. I am a electronic technician that works in the Semiconductor industry with equipment/electronic experience. Thank you

    I have replaced the STK amplifier with the original part and purchased the service manual.



    The picture was brilliant for 6 hours and the blue lines re-appeared. I unplugged teh TV overnight and the picture was restored, but if went off after one hour.



    I have two questions:


    1. Possible cold solder joint? Also I used heat sink compound on back of IC and attached it to the heat sink. And would I have to purchase another IC?

    2. Another component in the Blue Vertical circuit? possibly a bad capacitor.

Your Convergence ICs have failed. It is very common on rear projections. 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.

Monoscope signal how to get it Mitsubishi VS-6043 rear tring to adjust the picture its all warped looking got tv out of ditch tring to make it work


does the convergence align or move? how is the picture distorted? if the picture aligns but is just warped, use a jig or some string to have some straight lines to reference for your geometry and convergence. the monoscope signal is hard to find and mits had it on a vhs tape back in the day. it really just helped you get the horizontal and vertical size and get a round circle to fix the warp.. just try to make all the grid points about the same distance apart and make it an even grid.

Mitsubishi VS-55609 distorted Picture Flickers


This is a convergence problem and not really a DIY Many amateurs try it to save money but end up spending more on it than a professional. There are dozens on here that managed to fix it for a day or two only to have it fail again.

cost of fix about $300.

Hour glass cannot adjust red horizontal convergence


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

One of your convergence IC's has either cracked loose or burned out. The IC will have to be resoldered or replaced and then the convergence circuits realigned. If you do not have experience in repairing convergence circuits then have a qualified tech handle it for you. This is by far the most common failure in the projection sets and a good tech can have it fixed in about an hour and a half. I charge $150 for that but shops in your area will vary, so call around.
