It's the same regardless of scan rate.

why does it worek ok at the Sony shop..
what is dfferent there?

Wish I knew.

You see the intereference in your car? What if you drive to the Sony
shop?

Well, I'll be taking it to work next week, which is fairly close to the
shop. If it does it there, then maybe I'll drive to the shop with it hooked
up in the car and see if it continues to do it when I get there. If so
it'll be pretty hard for them to deny its existence
