I have only just had my Epson TW-10H and am very happy with it. Lat night I had the projector running for about 4 hours up till 3am Playing on the xbox. I had it in Theatre Black mode and as I had finished I hit the power button and had the warning message that my epson was overheating! It said either the room was too hot or the filter needed cleaning, now as ive only had the machine for 3 days I no its not the filter. I do have my shelf above the radiator but obviously not directly over it but then again it was 3am and the heating had long gone off. The projector never cut out just warned me, I havent put it back on today but just wondered if im going to get this regularly?
