SOURCE: Displayed massege to check air flow

With most projectors there is a foam air filter behind a grill that is the opening to the cooling channels. A fan ensures air flow to cool the lamp, etc. This filter prevents dust from gumming up the works (and depending on design) may prevent dust getting into the optics. As the filter gets dirty it gradually cuts off the air and at some point a protective circuit kicks in and turns off the lamp.
If the projector is on you will feel a stream of hot air coming out of the exit vent. Projectors vary in terms of amount of air flow, so its difficult to define what is normal for a specific model. However, you can simply hold a hand in front of the vent and see if there is air flow (It will be hot air so, careful). If there is a "good" stream of air things are fine, but if only a very light flow is felt the filter may be dirty.
If the filter has not been cleaned or replaced recently make sure the projector is turned off and cooled down then take off the inlet cover and remove the filter. Clean or replace per the instructions for the projector (and periodically as defined .. but taking into account the operating conditions). Once cleaned turn on the projector and feel the "normal" air current for future reference.
Heat is one of the major causes of projector failure, so make sure cooling vents (inlet and outlet) are not obstructed and filters are kept clean

SOURCE: Projector overheating and turns off after 20 mins

I have a HP VP6111 projector that works fine on a table top but overheats ( overheating ) when turned upside down and hung from my ceiling. My solution...I went to Circuit City and bought two 80mm computer fans. I also purchased a 12V power supply from Radio Shack. I put one fan on front of my projector and the other on the back of the projector and wired them into the 12V power supply. I mounted both fans with velcro. The front fan pushes air and the rear fan pulls air. The projector now runs fine without shutting off. The fans are 12V and push 34 cubic feet per minute of air. I am very happy with this solution.

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?

Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.

SOURCE: Optoma projector overheat issue - fan comes on but switches off

Most projectors have air filters. Yours may need to be removed and cleaned. No air flow = overheat.

return the projector (still under warranty, if bought new). if it's used, reset the settings on the projector to factory default. if still nothing, replace the remore.

Optoma HD80 flashing blue lights


Sound like the original color wheel for Optoma HD80 is bad.

If the unit has been moved when hot.

If not, try un-plugging the unit for a few minutes and re-connect.

Hope this helps

Overheating


Try initialization the High Altitude fan setting in the menu set up. This will increase the cooling capacity and should solve your problem

Unit is shutting down after ten min


My unit never got to the point of actually shutting down due to overheating, but your problem may be related to what I experienced: A bent lamp heat shield.

My Optoma EP739 started exhibiting color-banding and strong color shift after years of great service. After trying other suggestions that didn't work, here is the FIX for my unit. I have not seen this posted anywhere else.


Problem: After 10-20 minutes of use, color-banding and then a strong shift to purple/green with almost no red. If the unit is turned off for 5-10 minutes to cool and then powered-up again the problem goes away, only to come back in another 10-20 minutes. Enabling the "High Altitude" setting in the Setup Menu helped for a while (a week or two) since it forces the main cooling fan run at high speed always, but then the problem re-appeared.

Reason: Overheating. The electronics are overheating. Like several people have suggested: First step: Open the unit up and blow-out/vacuum all of the accumulated dust. Assure BOTH fans (there is a small drum blower directly cooling the lamp and a larger regular fan that circulates air through the entire unit) are operating and clear of debris.

Once you have done that, then look for the REAL issue. With the front panel (i.e.the panel with the hole for the lens) removed and looking into the projector from the front examine the metal heat shield on the right side above the lamp. In my unit, because of years of service and heat, the aluminum lamp housing had deformed slightly, tilting this sheet metal heat shield directly INTO the air stream from the fan. This restricts the airflow enough to reduce cooling capacity. This metal shield should be high enough above the lamp to be TOUCHING the plastic case. If it is bent down and is halfway into the air stream then it restricting the exhaust airflow, causing the overheating.

Fix: Bend the heat shield back up so that it is not in the exhaust airflow. It must be ABOVE the airflow, protecting the plastic case from the heat of the lamp. This simple remedy fixed the issue for me. My projector has been running 2-3 hours a day for 10 days now with no banding issues at all. That's it. Simple fix.

My EP739 never got to the point where it actually shutdown due to overheating, but the root-cause may be the same. First thing you must do is clean out any dust and debris that may be restricting airflow. If that doesn't help then read-on...

My Optoma HD 72 flashes green like others have descibed, but if I run it in High Altitude mode it corercts the problem, although it it very noisey. Any ideas to what is causing this issue and how to fix...


sounds like the air flow is restricted and overheats using the regular fan speed.
check for air flow blockages inside and outside, filter problems, etc

Optoma EP739 Projector Overheating


Set the projector to "high altitude mode." It will be noisier, but won't overheat. I wonder whether using one of those $10-$20 laptop coolers underneath it might be a quieter solution.
