My TV color has yellow, blue and red shadows n the picture.


Enter Service mode.. Press Menu -0-1-5-7 in quick succession . From there select the convergence option. You should see 3 crosshairs -Red, Blue and Green. Green is fixed but Red and blue can be moved. Align both of them with green and see if the issue resolves. If not Try moving them around and see if the problem is cleared. If not you may have the inevitable convegence IC problem and the IC needs to be replaced. Let me know if that is the case and I will give you the procedure.

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

Convergance?


An STK IC chip = large,soldered in, requires chassis pull.
Replace both IC's for reliability,usually no major alignment
after repair. Sometimes, a resistor or two burns or changes value
This repair usually done by skilled technician.................T.

Tried convergance, but would work


probably need to replace the convergence ICs inside the TV. The Ic is about 2" x 3" and mounted on large aluminum heatsink. Usually 2 or 3 (depends on model)
