When turning on my projector today, I was surprised by the fans blowing very loudly. I looked at the unit and say the lamp light was slowly blinking. I thought, no big deal, I have a new lamp ready. Sadly after installing the new lamp, it still just flashes lamp when trying to power it on. I found an old lamp I had kept just in case, and it wouldn't power up with this lamp either. I guess it's possible that all three lamps are dead but, anything else i could try? Does it sound dead?
