Question about Epson EMP 720 Multimedia Projector
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.

If the light is blinking red rapidly, there is a problem with the lamp. If the light is blinking red slowly, there is a problem with the projector. If the light is red and not blinking, the projector is overheating, which turns the projection lamp off automatically. Let the projector cool for a few minutes, then turn it back on. Make sure nothing is blocking the ventilation vents. Check to see if the air filter is clogged. If it is, clean the filter by following the steps in your User's Guide. Let the projector cool for a while after cleaning the air filter. If the projector continues to overheat after you clean the air filter, the problem may be caused by damage to the cooling fan or internal circuits. Please contact EPSON technical support for assistance with the error, or take the projector to an authorized Epson service center.
