Hi , Here's my problem , i've just purchased the benq w7000 ... geez i love it but... i got this problem : Sometime the screen turned dark as if my dynamic iris has been ''sqeeze'' or ''block'' ,,, sometimes its complety black... so i turnes off and then its ok . This is not my cable or so... i checked. I spent the whole week without the problem and then : BAM !!! 12 times in a row in the same evening... i dont knoww what to do ... i will call benq for sure to get a replacement .
