If it looks 3d with colors skewed you have a bad convergence IC.

The model indicated uses 2 of the STK-392-570 chips; they are located on the middle circuit board and a pair can be purchased on EBAY for about 14 dollars plus shipping.

I have repaired hundreds of these sets with this problem and I have composed and have available step by step, start to finish instructions for the do it yourself person who wants to repair this problem.

If you want the instructions (they tell you everything you will need and exactly how to do it) let me know here by using the "add a comment" button.

Please reply and understand total parts cost for this repair should be under 35 dollars total and the repair takes about one hour.

Regards, SD TECH

    Fixya does not work in this way. I am happy you liked the solution but what you need to do is post a question of your own, you can in the title mark it ATTENTION SD TECH and if I see it, (I am in California) I will be glad to help you.

    You have several choices--you can post it in the free section or there are several levels where you pay for an answer, in the free sections some experts will bid on this to get you to decide if you want to pay or want a free answer.

    There are rules here which do not want help given to someone who did not actually post the question.

52'' Projection TV SONY

this is a problem with the convergence chip. you can try to adjust the convergence in the menu settings of the t.v.
pin cushioning will correct the curves, convergence fixes color seperation.

write the number down before changing them, in case you make it worse.

If the entire screen is curved, and it is not taking the whole screen, then you have a vertical deflection problem.

If the colors are double and do not match, with lines of different colors around pictures , then you have a convergence problem, often caused by a faulty convergence board.

The curving effect can be a side effect of bad convergence, or you may have both problems at once.

Unless you are a TV repairer yourself, better calling technical support. Usually you can ring the number listed on the owner manual.

Mitsubishi 1080 hd series 65" Curved picture

The problem is the convergence circuit.
Mitsubishi used two different types of convergence IC's in this series. The first is a pair of STK-392-570, the second is a single STK393-110. The only way to fix the problem is to replace the appropriate IC'S. In some cases the problem may appear to be intermitent or loose solder connections. Save yourself the anguish and replace the IC'S.
Getting the PowerSupply/ Convergence board
out to do this is tricky and I recommend a professional to do it. Hidden screws on the front of the heat-sink make it difficult to take out and you can break the board easily trying to force it.
