Optoma HD65 wishle while off
Tue, Aug 2 2011, 3:10PM
Hello, I have purchased a 2nd hand optoma and I am a bit concerned with something. When the projector is off (stand-by) I can hear a very low noise like a wishle... It is not very loud but it just makes me doubt if this is normal or if the projector could be faulty. Do you know if this normal? Thanks.
