Only 3 things cause no light: bad lamp, bad ballast, bad colorwheel, or bad fan. if you feel the fan blowing and the lamp is good, do you hear a high pitched whir? if yes, the colorwheel works and it may be the ballast. if not, or it chirps, it's the colorwheel.

I have an optima hd180 that will not power up. The projector was indicating a bad bulb, so I replaced that with a new one. Now it still will not power up and the fan does not come on either.


Problem w/ OEM bulb, it causes a lot of issues from my experience. Your ballast might have gone bad, hopefully it's just that. Check the voltage output of the ballast, make sure you're getting the proper amount.

I've just replaced the lamp on my Panasonic PT-LM2E projector and it will switch on but no light comes out. The previous lamp blew in the projector after around 2000 hrs. The indicators are as...


I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

Sounds like you lamp ballast has gone bad. I good way to verify this is, when you press power on the projector look inside the lens. If you see a small amount of light, then the ballast is good, and the lamp is bad. If there is no light then chances are the ballast is bad.

LP 530 Lamp does not power on


Did you cancell the bulb fault status in the main menu ie bulb hours when you changed your bulbs if not try this turn unit on and see if it works it may do.

To reset the lamp hours counter press and hold down the Volume minus button - , then press the source button whilst still holding down the volume button for 5 seconds .

If this works you can then verify that the lamp counter was reset by viewing the counter in the status window in the OSM

hope this helps... Regards Vortash
