Well I don't know where to start counting pins on the VGA connector.
I'll look it up.

Starting my count at one end gives me 6,7,8 intact.
Counting the other way makes it pins 7 that is missing.

Based only on this and the green hue I guess Sony just
has a differnet setup as green obviously has a return circuit.

Thanks for the reply.
I'll see what more I can learn from google than crack the case open as needed.

Hmm, looks like it's just a key.
Time to crack it open.

Thanks again.
