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)
Thank you

Sony post convergence repair problem


The flash focus is a joke in these sets--only adjusts a limited area and can make the set look worse--like having a cigarette lighter in your car--not really needed.

Flash focus rarely if chips have been replaced will SAVE the adjustments.

The set stores the convergence adjustments on a board inside--best way to adjust is with the Sony remote to enter the tech menu and adjust there--when done one of the numbered buttons is pressed and Save? in red appears--press same button again and it goes to green which means adjustments have been stored in the set.

The tech menu will also always give a much better adjustment of the entire sceen.

If after the Flash Focus™ feature has been performed, the colors on the FLASH FOCUS screen do no line up (converge), press the FLASH FOCUS button on the television to begin the cycle again. If the colors on the FLASH FOCUS screen continues to appear misaligned, service will be required .
NOTE: It is recommended to perform the Flash Focus™ feature about thirty minutes after the television has been turned on and keep the room as dark as possible.

Picture is distorted from center on my 65


You do have a failure in the convergence circuit of your set. If you are good at soldering you can replace the IC's yourself. They are on the large circuit board on the left side of the set looking from the back, and attached to a large aluminum heat sink. If you don't feel comfortable doing that, I reccomend removing the board and sending it to PTS corp in Indiana. They are pretty reasonable repairing boards, and a lot less than buying a new one.
