Remove and use fine bristle brushes assisted with a jet of air which will clean up the fine netting of the filter. It is important that the filters are occassionally cleaned so that there is no dirt accumulation within the lens unit that can reduce the life of the LAMP and save an expensive repair.

if the timer is reset, try cleaning the color wheel. Optoma HD20 Projector Cleaning this video is for an optoma but the color wheel is cleaned the same way in most DLP projectors. Dirty or dusty color wheel sensors cause the projector to shut down and act like its the lamp.

If you do not have a remote here is how to reset the filter time. Use the "Menu" bottun to get the "easy menu" to display. Push the down arrow until you get to "Filter Time," then push and hold the RIGHT arrow to reset the filter time. DO NOT try to reset using the "Reset" option on the easy menu, it will not work.

Hi there

In your Menu options there is a subfolder where it either reads lamp or lamp timer.

Scroll down to it and hold down you right or left arrow key on the Projector for a couple of seconds.

What you want to do is go to the advanced menu, find the filter time and using the remote hold down reset button for 3 seconds or so while the filter time is selected. This will bring up a reset menu and reset the timer.

clean filter and reset the filter timer by advanced options filter timer and hold reset till menu shows then arrow up and it will zero out.
