I've just ceiling-mounted a new Optoma UHD51 that arrived a few days ago and frustratingly there's a very pronounced constant "mains hum" type noise; I assume this is faulty rather than something you are expected to live with?
For the avoidance of doubt, this is a very different noise to the Brightness/Eco lamp fan that I'm happy with and the "mains hum" is there regardless of whether anything is connected to the HDMI inputs or not and regardless of whether the Test Pattern is on or off.
It's a shame as I was impressed with the picture quality over my old Sony VPL-HW55ES but the noise is far too distracting so it will have to be returned. I have a dedicated (blacked out) cinema room with a 137" screen, do I take a chance a replacement UHD51 won't have the same problem noise or are there alternative projectors I should be looking at? I wouldn't mind doubling my budget to £2500 for something decidedly better but can't justify £4,000+ for a Sony 4K...
