It sounds like you have a bad VGA cable. Check for a bent or broken pin in the cable. These often show up as a loss of one particular color: red, green, or blue.

Usually the unit will go into permanant standby if the lamp life exceedes its safe limit. I had the MT830/1030. To reset it I had to press the off button down for upto 20seconds which resets the lamplife. If not the off button it was the on button.

Good luck

You can't. That symptom is caused by failure of one of the LCD panels. Not worth repairing unfortunately.

Did you switch the display from the laptop to external? Can't remember exactly but there is a key about in the middle top of the keyboard that looks like a screen. You have to hold function/code then hit that key to turn on the external display.

Press and hold the power button on the remote control for 10 seconds.

Red, Green, and Blue signals come from different wires in the VGA cable.  This sometimes happens if a cable simply is not connected fully.  But it will also happen if the cable is damaged.  The damage might be visible in the form of a bent, broken, or missing pin.  Or it might be internal to the cable.
Try another cable.
If that's not it, then the connector on either your computer or on the projector itself might be damaged.
Also try another computer.
Components inside the projector could also fail.  But I'd bet on a cable problem any day.

Hi there

Sounds like a typical Ballast ( lamp's powersupply ) problem.

NEC... | Answered on Mar 26, 2008


In some such equipment, there could be a problem of overheating of some component or assembly and due to overheating, there might be some sensor which is as a safety measure keeping the equipment off. I had seen some such equipment which stopped working when overheated but worked again when the temperature was normal. My experience belongs to the time when there was nothing like shutdown and we had to manually off the overhead projectors. Anyway, one can check for excessive heating at places and then doubt a particular part of the projector which may require replacement.
