Epson Projector "Alarm"

[pistolpete12]

How do all
I have a epson EH-TW750
Its a great lil projector and does what I need, but I cannot run it in Eco mode as when I do I can hear a small alarm type beep coming from it
So it runs full power mode, but then the fan is really loud, which drowns out the beep

I believe the beep is from a low battery? i cannot find much on it or anything in the manual, or menu

anyone experienced this? or know how to sort or stop it

Thanks
Pete

There's a couple of possibilities

First it could be the fan bearing that you can't hear when the fan is running faster. Probably unlikely.

Second, are you using an original Epson bulb? Some Epson projectors will beep in eco only mode when a third party bulb is being used.
