My projector is not turning on and I am not sure why. A student bumped it today and it hasn’t been working since. The red warning light is on. I have unplugged the power source, my computer, checked air filters and cords, etc. and it is still not working, After I unplug and plug it back in I can hear it turning on but then the power light switce it to the red warning light.
If the projector’s lamp is not lighting when the projector starts up, then one thing we would recommend trying would be to borrow a working lamp from another PRM-20 projector (or a spare lamp for that projector you may have on-hand) and install that in this unit.
If the projector will not light the lamp at that point and presents the same LED behavior when trying to start up, please contact us for further instructions.
