Question about Mitsubishi WS-55857 55" Rear Projection Television

1 Answer

Convergence problem Ok, sounds like I have the exact same problem as another guy on here. My picture is having a weird problem. It bows down at the top and bows up at the bottom. Every once in a while it will go back to normal for a few seconds, then it's back to the problem. Someone else presented this same problem, only I didn't really understand the answer that he got. Thank you.

Bowed picture colors off


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

Sony KP-65WS510 Convergence Problem


You have a convergence problem. Here are some of the most common symptoms. 
Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in but stationary.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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

>>>Solution<<<< 

You need to replace the convergence chips and convergence resistors. 

Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

Convergence


sounds like you have a problem only with red and green. Does the picture bow? if the Picture bows then most likely you have lost all convergence. then is will be a convergence power board issue that will have to be replaced or repaired. If you go into setup and try to manually adjust convergence does the crosshairs move up and down side to side on both red and blue if they do. then you may just need a technician to adjust convergence in factory mode

Sounds like you may need the convergence amps changed and also resistors in that area and maybe fuses.

Sounds like the blue convergence circuit still not working.

Assuming both IC's are good, look for open soldered-in pico fuse.

Once bowing problem is solved,then convergence should adjust ok.
