You will need two convergence ICs they are both STK392-110 and you should also order four 2.2 ohm 2watt resistors. You can get replacement ICs and resistors at the following link with free instructions.

How do you fix convergence on a sony tv?

hello!
If convergence in your TV went out suddenly and severely, there is nothing you can "adjust". That's a parts failure, convergence amplifiers I.C. chip(s) went south. Needs repair! Period! Minor alignments could be done by applying "flash focus" or "manual convergence" off "menu", if available.Some models have "flash" only option. Anyway, make sure there is no large metal structures near the front of TV or large speakers nearby. that could convergence to go out. Try not to play with any adjustments, if severe convergence problem. you won't be able to fix it right and will corrupt memory settings for "flash" option.
thanks,
Alex.

Picture appears to be 3d

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
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 photos of convergence problems

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Toshiba Rear Projection Tv 40WH08B

If the convergence on one or more color does not align using the convergence setup procedure, that means that one or more convergence ICs must be replaced, that is the reason why you get bad picture.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.

I have a toshiba model 50h72 double vishion

Projection sets have two very common problems.

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. 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 more information and a DIY convergenece repair kit with instructions from the link below.

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

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
