Acer pd726w projector beeps

The projector comes on and so does the lamp, but the lamp shuts off in about 5 seconds and then after 30 seconds the projector beeps 3 times and then a few seconds later it beeps once. The lamp indicator lights red on the unit. Does this mean the bulb is gone? It has had less than 300 hours since new. Please help, thanks.

    Did you get the problem fixed? We had the same problem, but the projector worked properly the next day. I checked the manual, the projector made a beeping sound if it detected that the lens cap was closed. But the len cap was not closed. We do not have a clue what's wrong.

    I never found a solution, it seems this model projector has some major issues with bulb life.  The manual says it beeps twice if the lens cover is closed.

I hate to echo this problem, but did either of you ever find the solution to beep code? Our church has had the projector for just two years and the lamp must have only about 400 hours on it.

Shut down after 30 seconds


Many projectors shut down if they cannot find anything attached to them.
Make sure you have a computer attached and sending an image out to it before you hit the projector reset button again.
It's a bit like the chicken and the egg since some laptops won't send an image out the cable unless it senses a projector, and the projector shuts down if it does not detect an incoming signal fast enough.

Acer projector blue light blinks and fan blows and no picture


As far as I can tell this looks like a lamp problem. Unless some of the fans are not able to cycle up tehn it would shut down before it overheats

Hi there

You'll have to settle for the ordinary Composite input on the Projector.

You do get a scart to composite convertor from most good PC & AV shops.
