Acer AT3720A humming noise from speakers
I just purchased the Acer AT3720A from Canada Computers yesterday and realized that there is a humming sound coming from the speakers even though there is nothing connected to the audio inputs. Is there a way to disable the audio output completely so that there is no noise floor whatsoever? I am in the GTA.
Also, there is a slight brightness (very small area surface of overall screen) in the top right hand corner of the tv on black scenes. i can see it a mile away obviously cuz i know it's there. i asked my girlfriend and she said she could somewhat see it but minimally noticable. will this go away with time or should i exchange like i have planned to do?
BTW the tv is great quality and i bought it at an incredible cash promotion price. as a student i am getting a great value for it but want it to be without these annoyances.
thanks in advance
