Troubleshooting

No picture
• The signal cable should be securely connected to the display card/computer.
• The display card should be securely seated in its slot.
• The Main Power Switch and the computer power switch should be in the ON position.
•
Make sure that the correct mode has been selected on the display card or system being used.
(Please consult the display card or system manual to change the graphics mode.)
• Check the monitor and your display card with respect to the compatibility and recommended settings.
• Check the signal cable connectors for bent or pushed-in pins.
Power button does not respond
• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.
Image persistence
• Please be aware that LCD Technology may experience a phenomenon known as "image persistence." Image persistence occurs
when a residual or "ghost" image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors' image
persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate
image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the
monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.
NOTE:
As with all display devices, MITSUBISHI ELECTRIC recommends displaying moving images and using a moving screen saver at
regular intervals whenever the screen is idle or turning off the monitor when not in use.
Image is unstable, unfocused or swimming is apparent
• Signal cable should be securely attached to the computer.
• Use the OSD Image Adjust controls to focus and adjust the display by increasing or decreasing the fi ne adjustment.
When the display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.
• Check the monitor and your display card with respect to the compatibility and recommended signal timings.
