Did you check the voltage for the convergence chip? if the chip was out, there is a posibility that the fuse has burned.

Convergence problem---set uses two of the STK-392-560 convergence chips.

Both will have to be replaced and set adjusted with remote.

Total parts cost on EBAY under 25 dollars.


I can tell you what is involved.

see attached photo of typical convergence problem and typical convergence chip.

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

1 Answer

Red color is out of adjustment


The convergence circuit on these sets uses a digital correction signal sent through amplifiers (also known as convergence ICs) to electronically correct the convergence. If you can adjust the convergence with the remote and everything moves as it should then it is likely not the convergence ICs at fault. It is likely the digital convergence unit (DCU) that is not storing your setting. If you find one of the colors won't adjust or move properly to your satisfaction then it is likely one of the convergence ICs and possibly some resistors as well that need changing.
This is not really a DIY project.

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.
