Hi I have posted this before, but under the HYUNDAI thread. Just at my wits end really due to the constant buzzing coming from the back panel. Should this be happening, and will it go off in time or is it a faulty set I have reason to believe that the screen is touching something in the panel, causing the buzzing noise. It also gets very hot. Is this normal for a plasma? Also, I have viewed the same model in Comet and it is quiet, no buzzing at all. I wondered whether this was due to it being on all day and wears off. can someone help!
