SOURCE: Convergence problem
you will need to replace the stk ic's they are mounted to 2 large heat sinks in side the tv. the ic numbers are on the chips themselves. i do believe it is stk392-510 for sony. once you have the number you can buy these anywhere online. just put new ones in and should be good to go. if this doesnt work then there are a few resistors and fuses by the ic's that sometimes fail.

Your TV has gone crazy on you because your convergence IC's have gone bad.
These IC's operate at a very high temp, and usually only last 4-5 years.
If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see 2 lage IC's , probably STK392-110, or STK392-120's or something close...regardless - you can go on ebay to order the new ones, but MAKE SURE they are Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may only last 2 months..
You will also need some "Heat transfer paste" - you can pick this up at radio shack. Once you remove the old IC's, test all the large resistors near them.. pull one side of the resistor out of the board so you can check it out of circuit. they will usually have the value in Ohms, printed directly on the resistor, but you may have to use the resistor color code to find out what value they are....However, usually if there is any damage, the resistor will look like it has been HOT or fried. replace the IC's and any bad resistors, and you should be good to go. If you need to order a resistor or two,
http://servicemanuals.vstore.ca/index.php/cName/convergence-resistors If after replacing the IC's and any defective resistors, the convergence is still bad, make sure to use a multimeter to check ALL fuses on the boards, --- sometimes when the IC's go, they will take out a fuse to the convergence power supply. If you find any bad fuses, replace them accordingly! If this STILL doesnt make it look right, you will need to find out how to get into service mode and do a coarse convergence adjustment. This information can be found in the Service manual for your set. If you dont have one you can download it at manualuniverse.com
Hope that helps!

Hi, thank you for visti fixya.
Here is your solution:
Replaced, IC8001 and IC8002 Part number STK392-560 and check pico fuse beside STKs ICs ( yellow pieces), go to :
I will be here for future questions.

SOURCE: The convergence is way off
Hi, thank you for visit fix ya.
Do you replace STKs ICs?.
If so, you need go to service menu tv.
With you tv off, press on your remote control:
display + 5 + vol+ + power.
You will go to service menu tv.
NOTE: Be Careful before you do this, because if you don't know step by step convergence adjustments.....YOU WILL MESSED UP YOU TV.
I recommended if you don't have electronics skill, take the tv near to tv shop.
Any question I will be here .
( I need model number tv, please)
