Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

Red Convergence Yesterday I turned on my TV and the red covergence was off on the top right and bottom left. Some of the red crosses are slanted and cannot be moved up and down, only left and right. Is this a problem with the convergence card or something else? How much should I expect to pay for repairs.

Re: Red Convergence

Yes the IC's and possibly the fusable resistors went out on the convergence board of your TV set. If you have soldering experience and some pratical electronic's experience I would say go into the set find the Two stand-up STK###_### IC's and replace them. Bur if you have no experience, leave This repair for the pro's. They should replace both IC's at once and should cost somewhere arounf $250.00 to $375.00 to repai.. Good Luck

You need to replace the convergence amplifiers. Mitsubishi part # 267P155010 and generic part # stk393-110. If there are 2 of them in your set, replace both.

My panasonic PT-47wxc43g projection tv has developed shrinkage in the middle of the screen on both the top and bottom. The picture has an hourglass on its side appearance. The picture is now also too large...

This could be a problem in the convergence board which will cost of repair would range 400.00 or so.
You can get the convergence repair kit at the following link which contains the parts and step by step detailed instructions.

Convergence lines are SLANTED. Red line is above

Your TV most likely 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 Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Top left and bottom right images/letters distorted.

I can fix it for $325? 213 880 1795
It was a convergence problem, both chips goes bad bad also look for bad resistors around the circuit? This is not an easy repair for non skilled person? You need to realign it after replacing the chips? Don't be cheap pay someone to do it right?

Red will not converge even after I replaced both IC's. Please Help ASAP!

I have a phillips in my office like this. There are a few things to check. Check the resistors around the red convergence ics it is probably open resistor or resistor fuse take your time and check all the resistors.In rear cases it could be the surface mount ics on bottom of convergence board i hope that is not the case.
