My projector won't go into standby mode, it looks like it's lighting up only half the power button, blue. I've unplugged it for 24 + hours and as soon as I plug it back in half the power light comes on. It doesn't power up either or go into standby mode. I've replaced the lamp and that didn't do anything either.
SOURCE: Lamp will not turn on.
If the ventilation fan is not spinning you will really have this problem, because if the fan is not working overheating problem will arise and will lead to this problen, so you will need first to replace the ventilation fan and that should fix this problem....
Hope that helps........
SOURCE: lamp and temp lights come on after power up and stay on. Lamp only has 330 hours on it.
OK, that explains it. The bulb you have installed in the projector might be the original bulb that came with the projecoter when it was new. Just becuase it states 334 hours does not mean it is new. In fact, you could have a original bulb with 3000 hrs and reset the hour timer on the projector, which means your 3000 hour bulb might have 3334 hours on it because the person who owned it before you, reset the hour timer.. Best bet, buy a new bulb and reset the hour meter and see what happens. If you have the same problem, then your ballest might needs to be replace which is rare...

Without more info, I'll tell you some things to check...Make sure the power cord is still plugged in firmly. With the unit unplugged, check the lamp for damage, looseness, etc. Was the unit hot when you moved it? If it was, the lamp was more prone to damage due to the heat. Always be VERY gentle if you have to move a hot projector for any reason. Did the unit sustain any hard impact while moving? Impacts crack boards, loosen connectors, and damage lamps. Make sure the lamp door is closed completely--there is a switch on the door to prevent the projector from coming on if the door is open. Make sure you didn't press any buttons on the unit too hard while holding it during moving.

Problem 1) The projector should put out a burst of 7000-15000 volts to start the lamp, and then immediately drop down to 60-100 vlts to keep the lamp lit. It sounds like the bulb blowing took out your ballast, or the ballast going out took the bulb (uncontrolled current = overheated bulb = boom)
Problem 2) Thats not a problem at all. HID lighting uses an arc to create light, just like welding creates light. Since it uses an arc, and not the heating of metal, there is no filament to test the resistance of. All the bulb is, is a special mixture of gasses and two very durable electrodes, with a gap in between.
