I have a benq w100, it's pretty old but still works pretty well. During a recent trip something has broken and even if the projector seems to be working, when it starts there's a loud noise like a fan was hitting something and after a minute more or less it stops and the temperature led goes on. I've opened it and the 2 fans in the front seem to be ok, the noise seems to come from the area below the board but i can't see or access that area since none of the screws seem to enable me to remove the whole board. Anybody knows if there's a third fan apart from the 2 in the front or what can be the cause thanks!

Hi,
Check if the unit has a Filter Timer ? If it does have one - check the hours on it and reset it.
If the problem still occurs or there is no filter timer in the Menu - check that all your fans are running.
Hope this is of help
Goodluck,
Please don't forget to rate the solution.

The fan has again got burnt out. Try replacing with the fan of the Benq Brand or a compatible one as depicted in the manual or contact:
