Question about InFocus ASK-Proxima C170 Projector, Factory Refurbished Multimedia Projector
My projector does not power on. I have replaced the lamp but no luck. What can be wrong there is no letters coming on the display, can the problem be blown fuse somewhere?
Please check the power cable then fuse.

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
