SOURCE: 52 inch tv has a warped picture with a rainbow type ark at top

This set needs a major repair. there are bad connections on the power board and a fuse is blown. You pretty much need a technician to fix this.

SOURCE: picture is warped (three colors diverge at edges

WS-55857 uses two STK-392-570 convergence IC's----you may have bad solder connections on them but what is more likely(I have seen this in sets that Mitsubishi made that use this chip) is that some of the pins are broken loose inside one or both of the chips.

Considering the labor to get the board out to resolder it, might as well just replace BOTH of the chips------Usually this repair can be done right in your home and takes about an hour.

If you are able to do it yourself you can buy both chips for less than 15 dollars on Ebay; if you need help I have complete step by step instructions for this repair that tells what you need and how to do the repair---if interested I can email them to you.

If you are not able to do the repair most shops charge 300-400 for this kind of repair; look in your area and if they say "needs to go to shop" keep looking; any good tech can do this repair right in your home.

Now is the slow time of year for TV repair shops so look around--I do this kind of repair here for 200-250 depending on the set --right in someones home! I have done hundreds of these sets.

If you need any help or would like the instructions reply to this comment here.

I do this for free here so if it helped you take a minute and give me a vote here.

Picture looks like it is warped at the bottom and top of the picture. Have picture, no problem there, just not a centered picture anymore. Looks like the top of a half moon on the top and botom.


This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • 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. Power light will blink. TV may also make a chirping noise.
Here are some images of convergence problems.

Warpped TV picture


There are two problems here but may be caused by one component

The flyback transformer or transistor equivalent is faulty The colors are warped convergence controls which may be due to a faulty sustain board or part of the first problem. DIY is not an option and repair estimate is about $3-400.00

Projection TV sets have two very common problems listed below.

Problem #1) 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. 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.

Here are some of the most common problems with these sets...

*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

*Dull looking picture
*White looking picture
*Halos around objects

Rear projection - convex distortion / ghosting / expanding screen


The most likely cause is shorted convergence chips and possibly a few pico fuses.

White dashes across top left of TV screen


That is what I was going yo suggest. You can also adjust the picture size. "Just" will show all of the picture even the distortions on the edges. "Full" will in effect overscan and trim those edges off.
