Prm 25 projector


Not what you want to hear but this error means the lamp did not ignite. The most common problems I have had with projectors has always been the lamp itself, so if you have another or know someone with a good lamp try that first.

I need instructions on how to replace the lamp in the promethean prm-25 projector


Make sure projector is unplugged and cooled down, lamp can be very hot
Remove the cover over lamp area
There are 3 screws in lamp unit (they have little arrows that point to them even) or check against new lamp to make sure you take out the correct ones
Pull straight up, place new lamp in securely and screw back down (screws are attached to each lamp set)
Place cover back over lamp area and screw closed
Reset lamp hours by hooking up your computer to board
Get to lamp reset screen
Press down up left right arrows in sequence then press return button in middle

LP600 - Grainy picture, very poor quality


Single chip DLP projectors use a spinning color wheel between the lamp and the DMD (mirror chip) to produce colors. If the wheel rotation/synchronization is disturbed, colors will not be displayed correctly.
In my case it looks like the wheel became un-synchronized, probably because the projector was dusty/dirty inside (a light senor is used to detect the wheel position), resulting in a grainy, slightly flickering image.
I simply blew out the components with a can of 'Dust-off' and, using a small tool, rotated the color wheel by hand to make sue it wasn't rubbing or jammed.
I reassembled & started the projector and the image was back to normal.

Color


Hi, If you have tried other video sources & still get the same results. It sounds like the motor that turns the color wheel is going bad, These motor's run from 5,000 to 10,000 rpm depending on model & are usually the first point of failure in a color wheel based DLP projector, If you don't count the lamp.
Overtime it may begin to make a squealing noise. Usually you can find replacement motors on the internet by searching the part number printed on the motor google is great for searching part numbers.
