Mitsubishi HC1500 Noise

Hello All,

I got my first projector today (Mitsubishi HC1500) and started it up. However, the system itself has a loud whining noise from the first time I started it up. I don't believe it is the fan but unsure what else would make the noise.

I am running on low lamp setting and whenever I start up the projector, it hums normally and at an acceptable noise volume for a couple seconds (similar to the hum when you turn off the projector and the fans continue for a minute). Then, the loud whining noise comes in (I am able to hear it in the kitchen when the projector is in the living room 20-ft away). The whining noise continues until I turn off the projector which goes back to the quiet fan operation on power-off cool-down.

Can you please share with me your experiences on the noise level of the HC1500 projector? It is suppose to be 26 db in low mode and I was expecting the low operating sound from reviews and this forum. Any guesses on what is making the noise is appreciated as well - unless this is the norm.

Thanks!

Thank, I will get it resolved under warranty.

Also, can fellow HC1500 users with properly working units tell me if the normal operation audible noise with low lamp mode will be similar to the 1-minute cooling period after turning the projector off?

I would like to get a feel for the operation noise of the HC1500.
