Convergence problems WS-55807

At first the blue convergence would not line up and would not adjust properly. After trying to adjust the red and blue, cannot adjust the red convergence at all vertically, horizontal is ok. Is there a fuse associated with this, that might have blown? Where are they located? Looked in the back of tv but can't find them. Please post any suggestions. Thanks!

Re: convergence problems WS-55807

On this model if the fuses that protect the convergence circuit would open up, then the set would not come on. The convergence ICs probably have a cracked solder joint on the foil side of the circuit board.Re-flowing the the solder would help. I will always replace the convergence ICs when doing this job. The labor remains the same and you will have to pay a few extra bucks for the parts. Hope this helps.

The screen has bowed lines and different colors no sound

If the model as indicate here (WS-55807) YOU may have two problems: Convergence and a audio problem.

In customer menu select convergence and with the Mitsubishi remote try to adjust the grid of lines so no red etc--if bowed it will not adjust.

This would mean the two stk-392-570 convergence chips this model uses need to be replaced(I have free start to finish instructions for that).

The no sound may and is likely a second issue: speakers in the menu may be switched off etc.

If both happened at the same instant this model has a hard reset(not from front of set but with a 4 digit code and done with the Mitsubishi remote) This sets everything except convergence adjustments back to factory original.

It is called the OPTION menu.

So, did both issues happen at exact same time or what?

Parts for the convergence repair are under 30 dollars total and I can tell you where.

My mitsubishi ws 55807 turns on alright but the blue, green and red color are on top of each other and makes every image look triple. This tv was a gift from a friend and we moved it a lot to take it...

You have a convergence problem, if it happened after you moved it around then its either broken solder joints around the convergence modules(stk392-110) or it is a physical problem.
You could take the front screen off and see if the mirror inside has shifted.Also take the front and rear covers and look inside for anything that might have moved or cracks near components mounted on heathsinks. hope this will help. Good luck

Auto convergence no longer works on Mistubishi WS-55807

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. 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, Zenith, and others. You can get a convergenece repair kit wiith 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 - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You have a convergence problem, and the sooner you get the set into the shop the less it will cost you. It seems that you may only have bad or cold solder connections on the stk convergence ics. If you keep hitting it to fix it, its goingg to surge the parts then youll be looking at 300 bucks or more to repair. GET THAT SET IN ASAP. Good Luck
