I was hooking my laptop up through the s video to watch movies off my laptop...bad idea. One day I unplugges it and this happened. Is the 392-110 ic all that I need to fix this problem?

It's best to replace both ic 's at the same time,but it will fix the problem.

    There is always 2 used. One is for red / green and one is for blue/ green.If you just replace one the other will go out just a little later.Before you order the parts ,check the part # on the part. Mine shows STK392-110 are used.

Picture Bowed towards the center


It is a convergence problem, probably one of the convergence ICs has blown and must be replaced. Call the number in the last pages of your user manual to get repair service in your area.

Mitsubishi WS-48511: can't adjust blue convergence


I am guessing that you did the convergence menu 1.CONVERGENCE MENU "MENU 2159, 4 FINE, 5 COARSE, 6 MISC
2. There are Fuses F9A04 & 05 that may be open.
3. If you do the self test do you come up with 2-2?
4. Self-test on threads here or at ctechnicians.com
5. If one or both fuses open you will need to change convergence amps and parts.(Kit)

This problem is most likely caused by damage in the convergence output amp IC's; this model uses STK392-040. Fairly common for various fuses that protect the DC supplies for these amp IC's to open as well.

Picture is bowed at top and bottom picture perfect in middle of screen; colors seperating in corners convergrence is perfect


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

Convergence issues


Your TV most likely has a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • 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.
Here are some photos of convergence problems.

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.

0667c5f.pngSOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

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.
