Some Proxima projectors had power supply problems, which resulted in either a dead unit, or, in the early stages of failure, might take a while to come on (maybe even 10 minutes or so). At the college where I'm employed, we've had 4 or 5 of the DP2000X models with this problem. The cause was a bad electrolytic capacitor in the power supply, namely a 47MFD/25volt unit, in the primary side of the circuit. I have pics of this circuit board. Another Proxima model had a shorted ceramic disc capacitor, and a blown fuse. If you have someone who is technically savvy, they could check your model for such a problem

    Send me an email at, and I will then email back the pics (I'm heading out of town for a couple of days, so it might be Monday before I can reply). Please note that the Model you have may not have the same power supply unit (though the basic design might be similiar). Component values & locations would thus be different.

    Chansn's suggestion should be checked first- if you have a blown fuse, usually some component failure has caused the poofed fuse, and replacing the fuse without finding the other defects will only blow it again, and possibly poof some additional parts.

    Also, if you have the unit apart, and don't know where the power supply board is at, you could send a few pics, and I might be able to ID it for you, and maybe make a suggestion or two as to what to try.

Lights flashing

Replace the lamp. The lights flashing will also indicate what is wrong. Watch how they flash. Go to the manufacturers website and they way they are flashing indicates what is wrong (ex. 3 quick flashes, long continuous flashes...etc.) When you change the lamp reset the lamp counter in the menu and clean or replace the dust filters as well.

Rollei 35A slide projector - halogen lamp problem

Most all projection lamps of 1970 vintage are still available on the internet. There should be a 3-letter code on the lamp. Try using Google to search that lamp code. There are multiple vendors in the USA that have an amazing inventory remaining. Good Luck !! Jim

No light come on from the projector

Thats the projector telling you that you need to replace the lamp. Lamps usually lasts for about 2000 hours so if you had it for a while you may need to replace it. and enter your make and model or go to and find a few retailers in the US that sells lamps.

good luck

Projector does not turn ON

try removing the lamp, usually quite easy, you need to find the door for the lamp. lamps are customer replaceable, usually. If the lamp is bad you can usually see it damaged in the lamp. kind of like you might be able to see the broken filament in your normale house hold light bulb. good luck.
