Projector does not light up
Working on an OptaVision HDMI-80. When powered on, the unit makes a buzzing noise that seems to come from the speakers. The projector bulb does not light up, but all the fans are running. There appears to be power to the speakers, the fans, and possibly the LCD board, but the bulb is not lighting up. I am wondering if the LCD board is bad. Any suggestions. I can provide pictures of the unit if necessary.
Is this a good question?
