SOURCE: color out of line i looks 3d in a fake way

the convergence ic of your tv is place at the main board.It is a two big ic that is soldered to the PCB with heat sink. To replace it you need to use a soldering iron ,soldering pump and a screw diver..unsolder it to the PCB replace it with a new one.Apply a silicon compound at the back of the IC before screwing it to the heat sink.

good luck hope this helps..

I have a Sony projection TV KP-53HS10. From one


It is most likely the convergence board. Rear projection TVs use three lights to display the image. The image is aligned via the convergence circuit. After many many hours of use the capacitors and resistors on the board lose their tolerances. It is very expensive to repair if you take into account the price for a new TV and the quality of the image you will be getting if you do have it repaired.

Just went thru the same problem with my sony kv-34. There are two IC's on the D circut board located on the left side looking from the rear. If you can solder 18 pin IC's without making a mess it is possible.If you have a friend thats real good with a pencil tip solder device. I recomend putting sockets in where the IC's were as you won't have to worry about overheating stuff next to the IC's.Do a google search: Sony led flashes ad select the second hit in the list.

Good luck

Uniontrip, im afraid you have a problem some other 3 illion other rear tube projection set owners face or will face in the near future. Its called a convergence problem. You see there are Two IC's inside this set that correct the alighnment of the three picture tube alighnment to each other to get a steady straight picture. To fix this problem, both IC's should be replaced together as a whole, even if its only one IC bad now, you can bet your bottom dollar, down the road, the other will go bad as well. If you have any solid state repair experience and know how to unsolder and solder printed circuit boards, this is not really a difficult job to do, as they are two black IC's standing up against a metal heatsink and the lettering on them will start with STK###-###, the # being other numbers. Now since these are solid state sets and they really have noi USER replaceable parts inside them, it is always best for the non experienced to refer to a trained repair technician to do this sort of repair. Most of the time, a repair such as this, should not exceed a couple to a few hundred bucks. Good luck. Please do not forget to rate this thread.
