When I power on the projector the lamp comes on but there is a humming noise coming from the projector. No warning light for the lamp and the projector does work however the fan noise is loud and seems to be coming from the lamp. Is that an indicator to replace the lamp.
it is a indicator you need change a lamp fan. Open projector, and check the fan model number, take a photo, send a message to me. I will get one for you. I'm a repair man, I have a ebay store(lamp-book), you can contact me at there.
