This NEC VT 670 is mounted from the ceiling for a SmartBoard. Recently it blew a bulb, but after replacing the bulb the projector will no longer light up the bulb. The power light will come on, the fan starts up, but then when the bulb would normally come on, I get three beeps and then the status light flashes and the power light turns amber. I have found the above mentioned fuse to be blown, and have replaced it. My problem is, I don't know what caused it to blow, I can't find any bad readings on the circuit board. Is there any other fuses throughout the projector that I might look for. Kelly
