Cybervision 64 troubleshooting help!

[kidkoala]

Good evening..
I'm trying to get a Cybervision 64 card working in a A4000;
I use os 3.9 and i've tried Picasso96 and Cybergraphx V3 drivers, they both produce the same results.
I use a tv with native screenmodes to boot, and test the Cybervision with a Eizo 17" CRT and an old cheap LCD, using the test mode in the Screenmode program.
When testing Cybervision screenmodes all modes work, but the picture is very very dark, monotone and kind of slightly distorted. Dark grey or on the LCD almost green.

Any tips? are there any jumpers on the 4000 or the Cybervision card that affect this? I'm thinking stuff like Int/ext Clock signal like on the 3000 (guess that wouldn't produce a picture at all if wrong).

Thank you for kicking my butt towards jumpersettings, I was onto that but didn't have the energy

Now it's working!

The trick was to set the CPU CLock to EXT, and the CLK 90 Clock to INT, on the A4000 mainboard.
