I have just installed a lamp and I'm still getting no picture. Is this a problem with my lamp?


A:Maybe. Please check that the lamp is properly seated and plugged in, and that the cover is screwed securely over it, as most projectors and televisions will not light with the cover open as a safety feature. If it still does not fire after checking all of these factors, it might be an issue with your lamp or your television/projector; please contact your manufacturer's technical support line for more information.


I just installed my lamp and it is flickering. Is this a problem with my lamp?


A:Maybe. As there is mercury inside the lamp, it will be gasified when the lamp is turned on. During the gasification process, the lamp may flicker, but should stop after a few minutes. If it continues after a few minutes, there may be a problem with the lamp.


I just installed my lamp and there is a smell of burning plastic. Is this a problem with my lamp?


A:Maybe. A slight burning smell can be normal for the first few hours of use, however if the smell persists or gets worse, it could be the lamp overheating, please shut down your unit to prevent any further problems.


A number of white dots have appeared on the screen. Is that a problem with the lamp?


A:Not likely. Check the lens of your projector/television and lamp first for any debris that might be causing image issues. If there is no debris, it is most likely a problem with the DMD chip, which will need to be replaced


My screen has a yellow/blue/green tint or has gone black & white. Is this a problem with my lamp?


A:No. Lamps themselves only pump out white light, issues with color are an issue with the television/projector, either because of an aging LCD panel, or because of a bad color wheel. Please consult your manufacturer's technical support line for troubleshooting on this.
