Question about Projection Televisions

1 Answer

Our model 42h83 toshiba projection tv is having color convergence problems (specifically the green). We tryed adjusting the convergence but that doesn't work. We don't want to spend $400 dollars that I am told it costs if a repair person fixes it. Can you please give us the part number that is needed to fix a convergence problem. We have'nt had this TV for long and are disappointed in this breakdown of the set so early. Any other suggestions you have would be appreciated. Thanks Joan and Larry Mackiewicz

Convergence setup for toshiba 42in projection


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. 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, Zenith, and others. You can get a convergenece repair kit wiith 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 - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....

Since this morning my Toshiba 42H83 TV's picture is blurry and has red and green shadows. We have checked all connections and unplugged all devices.


Go into the customer menu for the TV. Select convergence and if you find the colors are skewed or will not align you have a convergence problem.

I am going to post a few photos here of what this looks like--not all will look the same but you will know if it is your problem.

If it is your problem I can tell you what is needed to fix it--for many it can be a do it yourself repair.

If this information helps you rate this solution as I do this here for free.

I have a yellow line on the right side of my Toshiba 50 rear projection TV and yellow shadows around people


It sounds like a convergence problem---go into the customer menu and select convergence---set should offer center and multipoint adjustment--in the multipoint look to see if the outer crosses adjust--if red or blue will not adjust somewhere--bad convergence IC's.

42H83 Convergence


Yes the convergence ICs need to be replaced, however so dont the six 1.8 ohm 1watt resistors as Toshiba recomends replacing those six resistors when the ICs are changed. You can get the 50H71 / 50H82 Convergence repair kit as the 42H83 is identical to the 50H71 series, so the kit will work for your model. Heres the link where you can get the kit.

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.
