Okay but probably involve series errors

Unfortunately, the first W710St had to be already exchanged.
The device had suddenly projected bright dust spots, which in dark image content auffielen.Weiter the lamp flickered at irregular intervals for 30-60Sekunden.Wie was here to read on, this sounds immediately on again when you switch from short-ECO in the STANDARD lamp mode. But it always comes back to this flicker at irregular intervals.

The second device has indeed after a few hours operation even flicker no dust spots, but the problem with the device has also.
I've been looking for the problem already with me, but can now say that it is neither the source player, even on cable liegt.Selbst without signal source (blue screen prompts) captures the lamp to flackern.Zufrieden to I'm not having this condition.
I'll call time on Benq and ask whether this problem is known, but am hoping there is no Erfolg.Leider do many companies first as if they heard of this problem the first time and you should send the unit.
As sure no one will sit down for hours and Benq waits until it comes to this flickering, the device will after some time so arrive back at me, as I have submitted it.

FYI: The first unit has been built according to cardboard label in March 2012 and the second in May 2012 Design.
