KP-48V85 Sony with Technician diagnosed Convergence problem
I was just told by the Sony factory servicemen my TV has convergence problems to the tune of $350.
Can I buy a kit and do it myself cheaper? There is a yellow, blue, and red halo around every picture..

Kt33, of course you can do it yourself cheaper, IF you know how to solder & un-solder parts and IF you have a voltmeter and know how to use it. Convergence IC`s and probably a few support resistors will have to be removed and replaced. IF you can do the above I can look-up the IC`s for you but your on your own with the resistors until you tell me which ones you need if any, let me know, BMW Rider

The convergence IC's on your set have failed. There are several web pages that detail how you can replace these IC's by yourself. Do a websearch for convergence problems and you will find your instructions. This webpage gives instructions on replacing the IC's on a Mitsubishi but it is similar to the Sony: http://www.techlore.com/article/22530/DIY-Repair-Replacing-Convergence-IC-s-on-a-Mitsubshi-TV-Set/
are you experienced technician ? if you are not you are gone to mess up your tv you need to replace 2 IC's stk392-040 check power supply if still ok and get in to service mode to make the convergence aligment and is not that easy contac andrews electronics in CA they have squematic for
This might be a convergence amplifier problem or a problem in the convergence coils. I would suggest that you have a qualified TV technician check this TV out. This problem is usually due to the convergence amplifiers malfunctioning, to replace then the two modules and their biasing resistors must be replaced.
you will have to go in the service mode. be careful as you could damage the tv if wrong settings are changed. with the tv off push on the remote display 5 vol+ power. now hit the 1 button until you see pje fdis on the upper left. now push the 9 button to enter convergence. you should now have a cursor on the screen. usr the 3 button to switch colors. use the directional pad on remote to move the cursor and the enter button in the center of dir pad to select or deselct a point in the screen. push muting and then enter to save convergence. now restart the tv and all done
