Benq W2000 problems
I've been having issues with my Benq W2000 projector ever since my bulb exploded after around 3000 hours. No warning, just exploded.
So I ordered a new original lamp at Amazon and replaced it, but the unit kept switching off after a minute or 2 because of a fan that had reduced speed --> seemed to be the fan under the motherboard, and since this blows directly onto the bulb this is an important one :-)
I opened up the top cover to try and remove as much of the glass as possible, but I couldn't get the issue resolved so I took it to a local repair shop to have it cleaned.
Once I got my projector back it indeed seemed to work again without shutting down. Only problem is there are now " spots " showing in my image, which are mostly visible in dark scenes. Below a link to some pictures.
I immediately contacted the shop and they told me to return the unit, I assumed because the technician forgot to clean something ( I could also still hear a glass fragment make some noise ). After a few days I got it back, installed it again, but nothing had changed.. They did not give me any information whatsoever, they just sent it back so I assumed they would have fixed it.
I contacted them again, but the only information I could get from them was that there is dust in the " lens " and this is a non removable part which cannot be opened, so it cannot be cleaned or replaced. Apparently it's just bad luck, because sometimes this lens is not sealed properly.
According to the technician the lamp/fan problem has got nothing to do with these spots so he charged me 20 euros shipping costs for re-checking the unit. (after I already payed 150 just for the fan "repair" without the bulb). What's even more ridiculous is the fact he claims that it's not that big of a deal these spots (I told him I can almost not use my projector anymore). You can check the pictures here:
The strange thing is, before the bulb exploded I had no issues with these spots. What could have caused this dust, or is this a different issue? And is there some kind of solution?
It's really horrible to watch a movie this way ..
Thanks for any feedback !
