My yamaha LPX 500 projector is turning on (green light comes on) then after a short time the system switches to red and turns off. I replaced the lamp about a year and 1/2 ago. I also cleaned the filter. What else should I do before calling a repairman?

exatcly the same problem ... did you need to get it fixed?
i have had the same problem and at first i changed the vent thinking that it was overheating
HOWEVER
when this problem occurs the projector tells me via its light notifiers that the lense cap is on when that is clearly not the case
i found that if you take the bulb out and place it carefully back in then it will reset all of the sensors and you should be good until the next time it happens
its a short term fix but it does work
