Telex SpinWise DVD Duplicator



I have a 7 disk DVD duplicator which does not work.

When I turn it on it is one long beep, the front display is blank, just filled with black boxes. (see pic here) Or I attached it.

Here is a photo of the controller, the blue dip switches I haven’t touched.

Any idea what is wrong with it, or what I need to replace to make it work properly? Could it be the power supply or HD? I am new to these, but work on computers. Any help is greatly appreciated.
