hi,i`ve read a few posts now where people have swapped thier sets because of probs.i`ve been pretty impressed with this set since i got it but have noticed lately a couple of probs that are starting to annoy. 1-when stood slightly above or from the right hand side i can see a whitish box where the input channels are shown. 2-every now and then the screen will flash.more noticable when playing on the ps2. i bought the set from comet and was just wondering from anyone else who bought from them and exchanged how helpful they are with thhe process. thanks for any advice.
