Question about Optoma DS303 DLP Projector
How old is the projector?? First, unplug the unit and check the lamp--A healthy lamp should have clear glass--not darkened, smoky, bulged, or blistered. Sometimes, by simply unplugging and then re-inserting the lamp, you cause the contacts to get a better connection, thereby making ignition easier. This is the simple stuff. If you have another, known-good lamp, insert it and try to get the projector to fire up. If this fails, or if after installing the original lamp the unit still won't kick on, the problem will need to be addressed by a service facility. When trying to turn on, you hear a "clicking" or small snapping sound but no lamp ignition, that is a symptom of a bad ballast(the circuit that ignites and keeps the lamp burning). Also, no sound may be heard. You can also look into the main lens and try to see small "lightning" flashes as the ballast tries to ignite the bulb. Usually, the ballast will try to ignite the lamp several times and, failing that, the unit is programmed to shut down.Hope I helped you.---Rick
