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.

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.
