First of all hi to everyone

I'm pretty new to Pachislo and Pachinko.
After alot of searching i got myself a Biohazard Pachislo
and there is the problem i have and can't fix.

The Screen above is all time green, i've check all cables and connectors.
And still no solution of the problem.

Does anyone know about the problem and how i can fix it?

thanks alot in advance!
