Last night my SP5700 started displaying it's REPLACE LAMP message, as soon as the lamp counter hit 500 hours. Knowing that I should have 2500 hours left, this left me fairly miffed, and I can't remove the blasted thing. I tried resetting the Lamp counter, so now it is sitting at '0 Hours' but the REPLACE LAMP message still shows. My only other thought was to update the firmware, but either the projector or my M1-DVI cable isn't working properly, as my computer can't connect to the projector, nor does it show up as new hardware on connection. I've never used the USB connection before, so I just don't know. I've sent a message to both Infocus and Lindy (who manufactured the cable) but I was wondering if anyone on here had a similar experience.
