Re: lamp warning lit ~1200hr NO warning & new bulb SAME!...
Maybe your power supply could be the problem or check the cable that link to the power supply to dc output.check with multi tester if there is power coming from the power supply .be careful with the ac input of the power unit.tq

Lamp LED should be lit when the projector is in Standby. However, the problem you are describing sounds like one of two issues. Either the lamp is bad and needs replaced, or there is a power 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.
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)
I had the same problem. There is an internal reset button just above the lamp that needs to be reset. You have to take the cover off, which would void your warrantee, but it's quite easy. My lamp only had 660 hrs, and I bought a new one too. So now I have an extra. My guess is that my filter was getting clogged causing an overheating situation and tripping this reset button which I'm guessing is a heat sensor.
No do not reset the lamp hrs. because the lamp might reach the ed of life and could blow resulting in mercury poisoning. If you notice there is a warning sign that pops up in red or something saying to change the lamp, it will shut down eventually during that warning time. You have gotten a lot of hours with that lamp and consider being fortunate to have such reliability. Buy a new lamp when needed as it will improve your experience.
How old is it ? Approx how many hrs have you used it? Was it set at Lo speed / low power or hi speed / max power on bulb and fan? Do you smoke in the same room? Is the unit ceiling mounted ( more concentrated hot air ). Have you had a power failure while the unit was on? The bulbs used in many projectors , although claiming 3000 or more Hrs ,are subject to early failure. If the unit or bulb is new ( less than 1 yr. old, contact the service manager at that co. and complain about short life; IThat works !
