Hey all, I dug my 2 slot CMVS out of storage and hooked it up to my JVC Broadcast monitor (DT-v1710cg) And the top of the screen has a pretty bad "curl" effect.

I've seen a suggestion before to try a 1k pot on the sync line. I tried this and adjusting it had no effect whatsoever, other than completely losing sync once the pot was turned all the way clockwise.

Are there any other things I could try?
