broken display for schleicher plc.

Hi guys.

We have an old machine with a schleicher modular plc system. The display which is a crt type (not a flat lcd panel) is about to give up. Blue stripes across the screen. I hadn´t had any luck finding a replacement for it on so my hope is that someone here has some information regarding replacing it.

The cable for the display is connected at a module called USW.

Thanks in andvance for any help..
