Question about Sharp DT-100 Multimedia Projector
Last week while watching a Christmas movie our Sharp DT-100 shut down without warning right during
projection. Now when the projector is powered on the lamp attempts to
light, which it doesn't, so the lamp LED blinks (green) while it tries
to warm up. The LED goes solid for a second and then starts blinking
green again. This happens about twice before the unit shuts down,
illuminating both the lamp and power LEDs (red). I tried resetting the
bi-metallic fuse (breaker), but it wasn't tripped. This is when I
realized we had a problem. We have around 800
hrs on our lamp(not even close to 1/3 the spec life of the lamp). Any
help would be appreciated. I don't really want to drop over $300 for a
new lamp only to find out that doesn't fix it.
Thanks so much.
I think it's capacitor issue on the power supply board. open it, look for power supply board and fine bloated capacitor and replace it.
