My projector makes a very loud, uncomfortable operating noise. It makes a fairly high pitched sound.
I measure (with the Iphone) at least 42 Db directly on the device.
Is this volume normal?
My second Samsung unit in house does have the same unpleasent operating noise as you describe. High/medium pitched at a strong amplitude. Mine is fine for the first 5 seconds after boot up when just the side fans spins with an acceptable swooosh sound. After that 5 seconds some high / medium pitched sound starts constantly that annoyes me to hell.
I did make meassurement with app on Iphone I do get 43 DB directly on it, on the right side I do get 55 DB. My ambience noise is 29/30A in the house. Holle 23, how much DB do you meassure on the side of your unit?
I suspect the back fan is not good.
Its not coilwine, it has a little of that if I place my ear to the side of the unit but from 1m I cant hear that anymore. This pitched sound I can hear from 5m in the house and also during movie dialouge playing at high volume.
I feel a relief when I turn the unit of. My first unit was whisper quite (actually it was perfect regarding noise) just made a pleasent swoosh and could be on constanly no problem (sadly that unit had a picture quality flaw) Has Samsung changed fan supplier?
