Question about Acer PD523 Multimedia Projector

1 Answer

PD523 no picture, led blinks

Sorry for my bad english anyway. so i have the problem i receive no picture.

when i start the pd523 it sounds like a cooler inside tries 4 times to start and stops again. then the cooler on the front starts running. the red lamp-led as also the power-led are on for about 30 sec. after the power-led blinks and the front cooler runs on for about a minute.

i already opened and took a look at the lamp, looks like new. lamp must have about 400 hours, 85% in eco mode. on last presentation we had to disable the eco mode.

    how time goes by ;)

    i gave the acer pd523 to an repair guy. he told me after checking all that it is the lamp so everything else is in order...

    i wonder after about 600 hours in mostly eco mode the lamp is not okay anymore... i read about lamp reset on other projectors, maybe this could work to reactivate before buying a new expensive one (and hoping it works longer)? is that also possible on pd523?

    any experiences with alternative lamps?

Hy !

Seems to be the colorwheel. When a segment is broken, the unbalanced wheel causes vibrations. Costs approx. 100-150$. Take away back and top so you can see if wheel is not complete.

Good Luck!
