Our projector is displaying the message 'Need to clean the air filter' and the red lights for lamp and temperature are flashing. There is good air circulation around the unit.
How do I remedy this, please?

Good info deserves a good thumbs up! Thank you!
if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.
flashing lamp light means the lamp failed to ignite. It could be a lamp
driver problem or lamp failure. Replace the lamp to resolve the issue.
If the issue is not resolved, then service the projector.
A flashing Temperature light signals a fan error. Turn the projector
off and allow it to cool down. If the light is still flashing after the
projector is turned back on, service the projector.
Here is some information on this model which I hope will help...
The lamp indicator lights when the lamp is due to be replaced. It will flash if a circuit abnormality is found. The temp indicator lights if an abnormal temperature is detected. If it goes too high it will shut down flash.
The lamp indicator is furthest away from the power switch if that helps.
If the lamp timer was approaching the end of the lamp life you would see a REPLACE LAMP nag screen when the projector is turned on. The fact that you have not mentioned this suggests that this is unlikely to be the problem.
The filters on the model are on the underside. There is a removable panel directly under the lens. You should not use canned air as you are blowing dust into the projector. It is recommended that you use a vacuum cleaner. Filters should be cleaned every 100 hours and replaced when the projector is relamped. You can wash the filter by hand with water only, ensuring it is dry before replacing it. Do not run the projector without the filter in place.
If power indicator light red and warning indicator red flashing than according to user manual :-
The projector has been cooled down enough and the temperature returns to normal. When turning ON the projector the WARNING indicator stops flashing. CHECK AND CLEAN THE AIR FILTER.
Experience:- 1. if the temperature is very low than temperature sensor maybe misbehave.
2. If anyone fan not working
so please you check fans.
(If lamp or lamp ballast unit faulty than after a time period the lamp indicator light ON not a warning indicator. I experience many times if any fan in projector are broken or jamed the temperature light if present otherwise warning light ON or flashing)
There is three indicators lights on the panel
1. lamp indicator.
2. temperature indicator.
3. computer input indicator.
If your projector shutdown itself without given any indication its mean that your projector function POWER OFF TIMER is on. You can off this function.
How: (two keys back side of projector one is menu second is a joystick witch have 4 arrow keys and center press is enter)
press MENU button to display the menu screen and then use joystick UP or DOWN to select the OPTION menu. press joystick to ENTER and then use joystick UP or DOWN to select POWER OFF TIMER use joystick RIGHT or LEFT to select DISABLE then press MENU two times to exit the menu.
If your projector shutdown itself with given any indication then
If LAMP INDICATOR flashing RED then lamp circuit failure its need to be repair or replace.
If TEMP INDICATOR flashing RED then the temperature inside and /or outside the projector is abnormally high.
CAUSE: The ventilation opening are covered. The room temperature is too high. The projector is located at high elevations (above 1400m)
REMEDY:clean the air filter. Remove the object from the ventilation openings or clear around the projector. Set the HIGHLAND option to ON
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.
The ambient temperature in the room is to high. Try lowering the room temperature. If that doesn't work get a small fan and place it near the projector to provide extra cooling. The projector is running border line on high temperature and just needs a little extra cooling.
Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:
When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.
Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?
If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.
If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).
Just so you know guys (and this procedure is not for the faint hearted!). I had the slow one second red warning light flash. I checked the bulb, which was find and I left it powered off for 48 hours. My projector is no longer under warranty and would have cost me over £300 to have it looked at. I ventured inside to inspect the boards, once I removed the main board to check the power supply I heard movement from one of the light ducts. It took me a while to removed enough to discover the fixing screw which holds the imaging cube in place (which is between the 3 light ducts and the projector lens) had come out (!?) and was rolling around inside the unit. This would also explain why sometimes I could not focus my unit properly. I remounted the imaging cube, put the whole thing back together and PRESTO! My projector is working again. email@example.com
