Hello guys!

I recently bought an Index GS30 and I am getting desperate...
The machine was standing around for a year and I am just trying to get it going again.
When switching it on, the screen doesn’t show anything, it only flickers.
So then I tried to delete the PC watch but even that did not work. The machine used to be connected to a PC and only the serial cable comes out of the NC PLC card...
I also have to add that exactly that card always flashes. A red light blinks on both.
I don’t know what to do next. Maybe here is somebody that is more familiar with the machine and wants to give me some help.

Many thanks in advance
