I bought a used Sony TV that I love, but the picture had a double vision. It does not line up and it has a shadow vison all the time. I tried the Flash Focus but it doesn't change anything. the Model NO...


Your best bet is to have a professional come out and align the guns professionally. It runs 100-150$ for them to come to your house and do it. If you need anything else let me know.
Thanks,

Replacement of Convergence IC'S


If your picture looks 3D then you most likely have a CONVERGENCE IC that is bad or a fuse that supplies 12vdc or 25vdc to that IC IS OPEN. Also keep in mind it could be a FRACTURED solder connections. The cost of the IC varies depending on which one it is.

My sony tv model # KP-46WT510 is showing a three D Picture with a red outline


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

its failure of Convergence Out IC chip and requires replacement.
TV has 2 IC chip in convergence circuit and I would recommend to replace both at same time.
Let me know exact model of Sony 65" TV to provide you more technical info.

Sony KP-53XBR45 convergence


Hey, found the problem. Your Convergence IC chip went bad. Buy one at Bluestar International Components (bluestar-online.com) - order part number STK392-010 for 6.99. I've read that there are two in the system and replacing them both at same time is a good idea...so, order 2. Now, if you are handy, it will require you to open the back of the TV and solder out the old chip and replace with new. If not, then you might as well call a TV repair person and have them fix. However, every place I've called works on a minimum fee for "large screen TVs" - the cheapest I could find in Atlanta was $399 minimum service fee. So, I'm going to risk the home sodering job .... it's a 10 year old TV and as good as it's been to me, if I screw it up, I feel I've gotten my money out of it. Good luck with your repair. My parts are on order.
