Background
The controller is the computer that runs PathPilot and controls your CNC machine. While the controller itself could be different (a tower, a brix, rev c, rev d, an operator console, etc.), they perform the same function in controlling your machine and providing you with a friendly user interface.

Reseat the power cable
Reason: The PathPilot controller isn't plugged in to an outlet.
Unplug and re-plug the controller’s power cable from both the outlet and the controller.
Restore power to the controller
Reason: The circuit breaker tripped or a fuse is blown.
Make sure the outlet you have your controller plugged into is active, by performing a voltage test.
Replace the video cable
Reason: The video cable is disconnected from the PathPilot controller.
For monitor troubleshooting steps, go to Controller Monitor (Standard and Touch Screen) Doesn't Work
Start the controller with only the monitor connected
Reason: There is a USB issue.
Power down you machine and remove everything from your controller except power, machine communication, and the monitor.
Power back up.
Does the controller boot farther into PathPilot?
If yes, attach one USB at a time until you find the problematic USB connection.
If no, check time and date in BIOS.
To get into BIOS, restart computer and rapidly press F2 or F10 (tower controllers), or Del (for brix, rev c, etc.). If your date and time are accurate, and you still are having issues, restore to factory settings.
