Check all fuses in the power supply and look for any bad connrctions on the PCB. You are probably missing the 130 volt supply to the horizontal circuit. Common reasons are: Shorted horiz output transistor; flyback transformer, picture tube arcing , bad power regulator IC. In short, you need to get a qualified tech for this symptom. Hope this helps.

Doug, convergence circuit is failing, involves removing one of the boards, replacing the convergence IC`s and probably a couple of burnt resistors, not a "layperson repair", requires soldering experience, accurate voltmeter to find the bad resistors, etc. I would suggest calling a tv tech for this repair, questions? e-mail me back BMW Rider

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

Got used Toshiba 57H81 and picture is fuzzy like 3D. Touch focus error message shows.


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Red color convergence on Toshiba 57H81


Often convergence issues do not require the entire board to be replaced. You can resolve it by replacing the convergence ICs. The part in question is STK392-110. You will need two of them and they cost around 10$ each. But replacing them is a pretty complicated procedure and I would not suggest it to someone without prior experience. A service manual should get you started in the right direction if you are planning to do this yourself.
https://www.completeservicemanuals.com/toshiba/crt-projection-television/57h81-service-manual/prod_1128.html

PS
: Disconnect from the power supply before you start the repair. Also read the legend, the hv circuits are denoted by a special symbol, so you will know what you shouldn't touch.

You may also need to replace the nearby resistors that may have popped the IC in the first place. Read the service manual for further details.

Good luck,
Sai.

57H81 projection tv has very wiggly picture.


This is the Hyper Module that needs repaired. There are several small sm caps that dry out in this model. It's the module standing up to the right covered by a can as we call it. I really don.t recommend you trying to repair it. One slip and that module is done and you can't by a new or rebuilt one anymore. Please let a repair center look at it and do the work. You won't regret it.

Toshiba 57H81Problems Please Help


On this model I've found the hyper module to cause lines (Left to right) in the picture. Usually at start up and half the screen, then after warm up, the set will clear up some or completely. Of course a picture of the problem would help in diagnostics. The hyper module must be soldered in, so, knowledge of soldering is advised. This PCB can be bought at: Andrews Electroncis or Tritronics. I do this job in the home, pick up for service should not be required.
