Why are the warning and power lights blinking on my promethean PRM-30A Projector?
If the WARNING (red) and POWER (red) indicators are blinking, it means the projector has detected an abnormally high temperature inside. Check the air filters and remove any objects near the intake and exhaust fan openings. Then, wait for the POWER indicator to stop blinking.
What to do if my promethean PRM-30A detects an abnormal condition and won't turn on?
If the projector detects an abnormal condition and won't turn on, unplug the AC power cord and plug it back in. If the projector still turns off, unplug the AC power cord again and contact your dealer or a service center for assistance and a checkup.
What to do if the temperature inside my promethean PRM-30A Projector is abnormally high and it won't turn on?
If the temperature inside the projector is abnormally high, the projector cannot be turned on. When the projector has cooled down enough and the temperature returns to normal, the POWER indicator will stop blinking, and you can turn on the projector.
Why doesn't the lamp light on my promethean PRM-30A Projector if the lamp cover is not mounted correctly?
If the lamp does not light on for safety if the lamp cover is not mounted correctly or removed, check the lamp cover and lamp cover switch (SW901).
What to check if all LED indicators are not lighting on my Promethean Projector?
If all of the LED indicators are not lighting, it indicates that the primary power supply circuit is not operating properly. Check the power primary circuit and parts such as the AC cord, F601 (Fuse), Power board, and SW902 (Thermal sw.).
What does it mean when the warning indicator light is red on my promethean PRM-30A Projector?
If the WARNING indicator lights red, it indicates that the projector has detected an abnormality in the cooling fan operation or in the power supply secondary circuits. Check fan operation and power supply lines, and the driving signal status.
