We are switching ON the Old CNC Machine with Fanuc 12M Control. After Switching ON we are not getting Display.
We checked the 9 inch CRT in ON condition, Brightness & Contrast Changing.
In between the System and CRT Optical Converter Card is There.
In optical Converter Card Green LED is ON Condition, While removed the Optical Cable Red LED (Err) is getting ON.
Kindly Suggest to solve the Problem
