Projector Image is Dull or Dim The likely culprit of a dim projector is the bulb. High bulb hours will require a replacement of the bulbs in the unit. While replacing the lamp can be done by the end user, it is important to realize that the lamp is usually one of the last things that needs to be replaced.
We recommend replacing bulbs after hours of use, which is well outside the annual use range for most recreational projector users. Often times, we receive calls from customers who have spent a few hundred dollars replacing their lamps, only to find that the lamp was not the cause of their discoloration, power on issues, or blinking status lights.
Quality lamps can be quite expensive and we recommend only replacing the lamps when needed. These OEM lamps have been known to cause power fluctuations, leading to power supply failure, ballast failure, or even main board failure. No Inputs Recognized by Projector The issue could be either software or hardware. Make sure that your projector is on the right display mode. Sometimes, broken remotes or broken buttons on the projector will prevent you from switching to the correct input, so test these too.
Cracked Projector Lens Assembly or Projector Housing Mishandled projectors that have been dropped may need work to replace physical features of the projector, including replacement of any mounting brackets for lenses, or the lenses themselves.
Lenses are not repaired, but they are rather replaced. For schools and businesses using projectors, especially high brightness projectors, a good Preventative Maintenance schedule calls for a cleaning and re-calibration once a year.
Churches and low hour users can usually get away with a semi-annual cleaning.
