There is a slotted panel on the projector held on by a screw or two. Take that off and should be right there.

Clean air filters. DO NOT BLOW INSIDE!!!
Take the filter out andust it out somwhere outside.

The projector lamp turns off after one hour.

Very likely the air vent is block or you will need to clean the air vent. The system track the hours of usage and when it is time to clean the air vent filter it will stop working. A clogged air vent will make the temperature of the equitpment rise. To protect the circuits and projector expensive light component it will stop working automatically. After cleaning up the air vent, see the manual how to reset the clock/timer for air vent cleaning timing, so that the lamp would not turn off.

Proxima ds1 not lighting


replace or clean the Air filters. Run the lamp reset command if you have.if not solved then check ballast unit which ignites the lamp.

try this also, press the poweroff button on the remote control for ten seconds, the lamp will reset to zero, if you run the projector more than 1100 hours earlier.

The filters probably need cleaning. Also check and make sure none of the vents are being blocked.
