Biohazard Pachislo green screen

[ChrisAD]

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!

So silly question.. does check the cables mean you just looked at them.. or have you unplugged and then reseated them? If you have not unplugged and replugged in cables do so.. also do not assume the problem is on the side with the screen do the same where the ribbon cable connects to the mainboard.
Another silly question..
When you power the machine up does it just do this? It almost seems like corrupt video memory or another component failure besides the screen. Lines and artifacts on a display are a dead giveaway of bad RAM.

Another test. How many cables actually plug into the screen? If you can isolate power and video (somehow) try powering the machine up with just power to the screen.. If this happens your screen is bad.

I've got more.. same as troubleshooting a bad laptop display.

I've check und unplug all cables so far, nothing broken or damaged.
When i power up the machine, everything is start to work exept the monitor, it's directly the green screen shown.
isolating power and video doesn't work i guess, somehow it's the same cable that give's power and video to the monitor itself.
i'm pretty much lost on solutions there, not sure what i can do left to fix this issue. :/
