Loose filter warning

Most projectors have a safety interlock switch installed on the lamphouse door and in the filter cavity. They are there to keep the unit from operating if one or the other aren't present. I'm not familiar with your exact model, but I've seen the lamphouse interlock switch in several Panasonic units come-loose, and slide to the point where the pin on the door doesn't push the switch any more. I would suggest looking around your filter for such a switch. The one in the Panasonic is behind a round hole, and is 'pressed' by a plastic pin on the door. Your filter may be similar. Hope it helps. :)

Unit powers up then shuts off after a few seconds

The problem you are describing sounds like one of two issues. Either the lamp is bad and needs replaced, or there is a powericon1.png supply fault. If you have tried replacing the lamp already, make sure you reset the lamp counter or the projector may still not function properly.

does the temp warning light come on when the projector shuts off? if so, you may also try cleaning the air vent filters and ensure there is proper air flow around the projector. if that checks out then have the projector serviced as the power supply is likely suspect.

My data projector eiki LC-Xb23 goes off without warning and the warning light is flashing

If the power light & warning light both flash red, this indicates that the projector is overheating. Once the projector has cooled down the warning light would continue to flash red and the power light would be solid red.

You should clean the air filters.

The filters are located on the underside. Disconnect all cables and invert. remove the 2 air filters located at the front and rear by pullingthe latches. They are both rectangular in shape.

Being very careful not to damage them, you should rinse the dust out and leave them to dry fully before replacing them in the projector.

This should cure the problem.

PT-L785U Projector

if the lamp warning light is flashing, this indicates a defective ballast (lamp power module). if the lamp warning light is lit steadily, then the lamp would be at fault.

My Panny AE700U shut down & won't restart

HI there

This is a faulty Mainboard that will need either repair or replacement.

If a Projector starts playing on and off tricks I have found it to be 99% of the time a faulty Mainboard.
