Need help with Sony Big screen pincushion

[Guest]

I need some help localizing area causing a Sony big screen tv (model
kp53v15) to pin cushion. Just started all at once. And the convergence in
the corners is way way off (obviously).

TIA

My experience has shown that these Sonys' have few actual pincushion
problems as compared to convergence issues. Would start by locating
convergence amps and the B+ fuses associated with them. If Fuses (3.15
amp GMA I think) are open, R & R both amps.
