Re: 50 " mitsubishi projection tv

This website:

says your model uses the STK393-110 convergence chip. Another site I looked at said that was a 6 channel amplifier so I'm guessing you only need one to repair your TV.

If you do some google searches on "stk392-110 convergence problem" you'll find some good sites that discuss how to repair the tv. The STK392-110 is a convergence amplifier that is used any many other sets.

Good luck.

if your picture looks 3d it is convergence problem.

This is a do it yourself repair if you have some skill.

I will tell you what you need and have start to finish, step by step instructions for this repair along with photos, and source for parts needed(parts cost will be under 30 dollars).

Where can I get a module and ic for a mitsubishi ws55807 projection tv?

If you are talking about convergence, this model uses 2 of the STK-392-570 convergence IC's which are located on the middle circuit board.

The board has not been available for a long time and one seller on Ebay has the chips at about 14 dollars for a pair.

Repair requires removal of the middle board and the chips are soldered in.

I do have start to finish, step by step instructions for this repair in this model; they tell you everything you will need and how to do the repair, I can post them here for you if you want them for free.

Considering that even if the board was available it was well over 100 exchange it is much cheaper and better to do it yourself.

Let me know if you have questions or concerns.

Boe in blue dynamic convergence curcuitry. Swapped deflection yoke on two tubes but problem still remains. Unplugged convergence plug on yoke and bow disappeared but unable to adjust dynamic convergence....

what's the number of the board where you unplugged the conv yoke, should start with 930_ that is the board you need. Try the with the part number or type in the brand and model when you have the number on the board, and they display price and availability.

Replaced convergence board, fixed problem, and now want spare.

The usual order of probability I have found is:

Electrolytic caps
Regular caps

Static testing OFTEN will not reveaal the failure.

Bowlike effect convergence all screwwed up

I suspect you originally had an intermittent solder connection on the convergence circuit board. This may have damaged the convergence IC's on that board by now if repairing those connections doesn't fix the set.

Convergence board

It wouldn't be the entire convergence board, you more than likely have a bad convergence STK-IC. Replacing the IC will take a good bit of knowledge and training as far as electronic repair is concerned, plus a complete convergence set up. In other words, unless your certified, you need to contact a tech. The convergence set up alone has driven men to drink.....
