Servos come on, but no display on monitor:

These instructions assume that you have first done trouble-shooting here, and you can turn on servos despite no display on monitor. The instructions below will help determine if the monitor is bad or if there is a cable connection issue.

No Signal to Monitor:

If "no signal" or similar message is briefly displayed, the monitor is powering up, but may be disconnected from the computer. Turn off the CNC, then remove the front panelRemove cover, screws, stow front panel and verify that the monitor cableVerify monitor plugged in is plugged in. (Note: to stow the front panel, you must remove top of plastic wire duct.) If the monitor is plugged in, first try unplugging and replugging it. Replace the front panel, being careful not to pinch any wires between chassis and front panel. Power up the CNC: If the symptom is the same, any VGA desktop monitor can be temporarily plugged in. If the desktop monitor displays normal boot-up messages, replace the monitor(part number 995-16-019).

Monitor Power:

If no message is displayed on monitor when CNC is powered up, the monitor may be disconnected from the 12 power, it may be defective, or the auxiliary power supply may be bad.
