I'm trying to understand, and I take this issue seriously.
What I'm trying to figure out is how it's causing a noise when the unit is unplugged. Is the sound coming from the actual speakers in the television set, or is it coming from behind the set?
We purchased the Samsung Plasma TV, the first week in Sept. from Best Buy and had the Geek squad sit it up and program it. It worked fine and had a great picture. However, during the middle of the night, while turned off; the TV started chirping very loudly. We unplugged it and the noise continued. During the day, it occurs after the TV has been on for about 2 hours. Shutting it off does not stop the deafening noise--even unplugging it does not stop the noise. We had the Geek squad come back out but the guy could not hear the noise at that time and said he thought it was because of the cable box. Cable TV came out an took the cable box off and the TV still made the noise at 3 am with nothing turned on. What kind of warrenty is on the TV--we cannot tolerate being awakened at night and have to leave our home during the day when this occurs due to ear pain.
