i have this Promethean prm-32 at a public school and for some reason it does not work anymore. but when left unplugged for couple days it decides to turn on again and work and the it loops again. so it stops working again and continues.
what could be the problem here?
Thank you for contacting Promethean Technical Support.
To better assist you with the issue reported, we kindly ask you to confirm if there any LEDs are lit on the projector. If so, do you notice a precise LED sequence?
In general, we recommend you make sure both the vents and the projector are clean and that the ambient temperature is between 5 and 35 degrees Celsius (41 – 95 Fahrenheit).
If available, testing a new lamp would help understand if the issue is with the lamp itself.
We look forward to hearing from you.
