I watched Perfect Storm last night on Sky Movies and noticed 2 vertical bars at the back of the tube on the 32PW9617. One is about 6 inches inside the left hand side of the screen and the other is 6 inches inside the right hand side of the screen. It was most noticable when the picture was very bright or kind of greyish. Once I saw I couldnt forget about it. Is it something to do with the panny tube I wonder? Maybe the set is faulty? Tried differnet settings but to no avail. Anyone else noticed anything like this?
