The parts don't cost too much, but do take about an hour to install. The worst part is in having to redo the entire convergence procedure after the new STK amps are in. Probably loking at $300 to 450 depending on what part of the country your in.

You need to replace Both STK ICs . They are Big Black ICs and will have PN# on them
example STK392-110
Mats has ICs 1-800-628-1118
Also check the Pico Fuse in Front and back Of ICs they look like resistors ,But will be Green or Yellow 5amp, 6amp, 7amp.

Blue and yellow, like double vision or 3d look

The convergence circuit has failed in the tv. These are the big STK chips on the circuit board. It typically costs $300 to fix at a TV service center. Requires replacement of two STK chips, some resistors, some fuses and then re-alignment of the CRTs within the service menu.

If you have proper soldering tools and can download the service manual, it is possible to do the repair yourself.

If you do not have any electronic background whatsoever, I do not recommend a person to attempt it.

We have a Sony KP046WT510 rear projection TV and the picture went to what I describe as what a 3D movie looks like without the glasses. I have tried to adjust the convergeance manually and red and blue...

THIS model uses two of the STK-392-560 CHIPS for this.

Both will have to be replaced and I can tell you best place to buy them and how to do the repair.

Total parts cost will be under 25 dollars from the seller I use on EBAY.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

Gettung double imaging with blue and yellow

Double check the model number---there is a 61swx10b---All of these sets use two STK-392-110 convergence chips.

Check my recent posts and you will find similar ones related to your TV. Both chips need to be replaced and you can buy them on Ebay for less than 20 dollars for a pair including shipping. Depending on how they fail there may also be a damaged resistor located near them.

If you cannot do this repair shop around your area as most shops will try to charge 300-400 for this repair.
Make sure whoever you get replaces both chips or you will shortly have the same problem again.

I have done hundreds of these sets and here charge 200-250 for this kind of repair. If a shop tells you it has "to go to the shop" keep looking as any good tech can do this repair right in your home in about 1 hour.

I hope this information has been helpful and if you have ANY questions or need advice contact me.
