I have a problem with a very shaky picture on my TOSHIBA rear projection TV model 42h83 I have tried the touch focus, all I really get is two horizontal lines of each color (RGB) they roll top to bottom...


Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:

Hope this helps :)

I have double vision on my projection tv (toshiba 42H83).


Sounds like your convergence chips have failed. This is a common problem. You can get a repair kit from www.TvRepairKits.com .

Color change


I had my stk's replaced, was able to take out the board and brought it to a tv repair shop, the fellow replaced the circuits and re soldered the circuits and heat sinks. Circuit Barn- Auburn, Mass. Jeff Murray did a great job. Reinstalled, and 56 point convergence, tv looks as good as new. I was disappointed too, because the set was purchased in december of 2002.

Very rare to have a "tube" problem--is the real issue red/green/blue mis-alignment?? If so,please read solutions written by me for same or similar problem,includes many different Tosh models.

Convergence problem with Toshiba TV 42H83


Your TV most likely has a Convergence Chip 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.
