We have a fanuc series 160i-LB (A13B-0193-B032)connected to our Mazak laser and the screen went blank today. I opened up the control and checked all the connections and don't see any problems. It appears to be running other than the monitor. I see to replace the entire unit is $4000 to $7000.

Is there any way to connect an external monitor? Anything else I should be checking to troubleshoot?
