You only need one STK393-110 Convergence IC and two 5Amp pico fuses. You can get the IC and the two fuses for less than 35.00 at the following link and they provide free installation instructions with pictures so you can easially do the repair yourself. Heres the link.

The picture has double images and looks kind of like it is 3D.


The tv have a problems known as a convergence problems,it dead.The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.The tv convergnece board,must have these parts changes on the tv convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

If it looks 3d you have a convergence problem.

This model should use two of the STK-392-560 convergence chips for this circuit.

Both will have to be replaced and a few other easy to check parts tested also.

If you have some expertise or have a friend who does I can step you thru the repair.

Parts cost will be if purchased on EBAY (I have seller I can recommend there) under 30 dollars total.

Let me know if you have questions and thank you for using FIXYA.

There is a blue color shift to the right making people look like they have a blue shadow. Thanks. Matt.


it is a convergence failure
you need new stk chips to fix
this is complicated and requires soldering
typical cost 150 to 300

if you are crafty i can give you ideas on how to improve the picture without repairing but you will have to reach near high voltage lines, let me know if you feel so inclined

Mitsu Proj TV WS-65711 needs Converg IC chip. Part Co$t + labor?


There is either a pair of STK392-570's, or
a STK393-110. Probly also 1 or 2 pico fuses for the +/- 26v line in the power supply.
Parts aprox 80.00 to 90.00
Labor 150.00 to 180.00
Plus service call fee if any.
So figure it up from there. Labor cost does vary from location to location. I do feel confident that capasitors are not causing this problem in the way you explained the symptoms.
Hope this helps,

I have a Hitachi 53uwx10ba has double colors red and bleu


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 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.

Convergence chip


Convergence ICs cost around 15-25 each there are only two of them. I would go ahead and replace both of them because if one goes the other one will follow shortly. I would make sure that it is just the convergence IC not something else, and if its over five years old dont pay more than $500.

Power supply/convergence issue...


Your Projo is a complicated piece of equipment, involving 3 picture tubes (like 3 tv's), convergence failures are extremely common, I dont think $550 is totally unreasonable, but I dont think it is a power supply issue if it is just effecting 1 color, usually it would cost around $100 parts $300 labor to repair, might be a little high, I suppose they are also charging you for pickup and delivery, I hate taking sets into office as that sometimes jars stuff loose or cracks boards.

No power with remote or manual power switch


Your convergence module is probably bad. It is a plug in module, so labor would be lower if the convergence settings are still good. The bill would be about $300.00 If not, the labor for convergence would add to the bill. If the whole job needed full convergence the cost would be about $500 to $600.
