Sony KP-51WS500 - Convergence Problem?

Hi All,

My KP-51WS500  has a problem.

I've gone over the threads, including the Sony Convergence Repair.

Thank you, it was very informative.

The question is how do you identify a convergence problem?

Attached are several pics.

Do you believe it's a convergence problem or something else?

Thanks,

Leo
