The monitor does not display anything,but the power is available on the machine. Can anybody help?please help me my colleges.

what kind of monitor?

If it's a Planar brand, it may have gone into "Safe" mode. Call the manufacturer and they can explain how to "Reboot" the display.

Hello,

The monitor likely failed. Turn the system on and wait a few minutes. If you have a printer attached to the system, try to make a print. If the printer works, it is a monitor or cable issue. If it does not, the CVC or IO board in the most rear slot of the scan converter is likely bad.
