The problem is probably that one or both of the STK convergence chips have failed. These control the convergence coils around the red blue and green guns and are the most common cause of sudden convergence problems and the protection circuit shutting the TV down when turned on.

I can post details of how I replaced these on my Toshiba 40WH08B. Yours should be similar.

How to fix the convergence on a toshiba TP55D81 tv using the remote control


The convergence is adjusted with the remote by entering a tech menu and adjusting there====if convergence is really bad adjustments are not going to fix it.

The set should have in customer menu a limited convergence adjustment with up to nine points where you can adjust---if it will not adjust there in some way----convergence circuit needs repair.

Have aligned all the + signs already but is still out of focus!


with the original remote go into the customer menu and find CONVERGENCE---you will be able to adjust a single cross and also if you continue it will give you several points on the screen with a grid of lines----what you are looking for is does the red and blue adjust in all areas----if either will not adjust up/down and left right---you have a convergence problem--need to replace both convergence IC's and then align the convergence. Hope this helps you.

I have a 42'' where the color in the top left corner seems to have separated, or shifted. The picture is ghosted in red and green in this area. It happened all of a sudden.


Your TV most likely has a convergence 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.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

I just replaced the two convergence ICs in my Hitachi 53UWX10BA projection TV and it looks very good in the middle of the screen top to bottom, but as you go out both right and left the convergence gets...


Yes, it sounds to me like it only needs touch up in the tecnician convergence menu. Which you get into by pushing the service only switch after the set is on and then using an original Hitachi remote control to do the adjustments.

Tp55f80 tv. to much red on screen


You have a convergence failure. It may be possible to simply re-solder the pin connections under the convergence output ICs as they have a tendency to develop cold solder joints which cause intermittent mis-convergence. If the solder connections are good, then replacment of the ICs will be necessary. Expect to pay $350-450 to have a toshiba servicer fix this.
