Hello,

Newbie here. I just bought a bulb replacement for this projector, I decided not to go with the whole lamp for various reasons. I replaced the bulb, seemingly placing everything back the way it was while removing it. When I turned it on the bulb doesn't light up at all. The power button will blink for a couple of minutes then shows a red light on the Lamp indicator. So I know I did something wrong with replacing the bulb, but what? Is there anything I need to be careful of when replacing the bulb?

I tried putting the old bulb one back in and still nothing. I did try to blow out dust with compressed air. Also I did touch the bulb with my hands, and I later learned that oil from skin can burn out the bulb. But I never notice the bulb flash in a burn out when turning on, nothing lights up.

Any suggestions?

Thanks,
Eric

Issues with 3rd party lamps are numerous. From electrical issues that these lamps can cause, to complete projector failure due to incompatibilities between the projector and the lamp installed.

There is no good answer on this. I would recommend getting a factory original lamp if at all possible and using that. But, it's possibly to late already.

I did try putting the original bulb back in since it hadn't completely gone out before replacing it, but the same thing happen. I'm not sure if that helps at all. But is there a possibility that a third party bulb could damage the projector?

Yes, in fact it happens all the time. They can be poorly designed, not compatible, draw incorrect voltages, run hot, etc.

The list of issues which have been reported with third party bulbs is rather long and very unfortunate.

Since the original lamp isn't working either, it may have damaged the ballast in some way, which could be the issue now and the projector may need to go in for repair.

Any idea what voltage is ultimately needed to light these bulbs? A buddy of mine took a look and we are seeing a 50V AC signal while the projector is simply plugged in. He's going to take a look at it when it's turned on to see what the voltage spikes up too.

Unless that shows some weird results it seems as though the ballast has a correct output, which only then would point to the bulb.

Could I have mishandled them and caused permanent damage to both bulbs? Maybe they burned out and I didn't even notice.
