I had the same problem. Repair guy came out (it was under warranty) and replaced it with part # 392-110, an IC. System needs two of them, I think, at about $26 each (www.partstore.com). Good luck! --Mark Wild

My picture is wavy and out of focus. when i touch the auto focus it goes through the function but ends with failure. it is a toshiba 42h81.

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

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 a convergenece repair kit with 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 - 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

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

When the TV is on, on the outlines of people and text are in Red and Green lines. I have tried the touch focus and it is not working. it is saying that there is a "touch focus error" can I manually adjust...

you need 2 new convergence chips, part number stk 392-110, also check for burnt up resistors next to the chips, major disassembly and soldering, you probably need a tv repairman.

Toshiba 57h81 green will not focus

Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

Red is out of convergence

I would stay away from that repair man. That model has just one Convergence IC number STK393-110 and it takes about 45 minutes from start to finish to remove the old IC and install the new one. You can get the replacement IC at the following link and they provide free instalation instructions with pictures so you can do the repair yourself for less than 30.00. Heres the link. You need just 1 STK393-110 Convergence IC they have free shipping as well.

Red line

Need convergence IC's and probably several resistors that have changed value. Seek professional help, someone who uses ORIGINAL ic's, not generic or knock-offs
