Yikes. I should have used present perfect tense and written Sharp has had banding problem. I was simply using Sharp as an example. My point was that every brand has had problems including Samsung, LG, Sony, Toshiba, etc. etc.
I really am not an advocate of any brand. Like I have stated, problem-free one is the best one, regardless of the brand. First-tier brand products seem to be pretty much the same to me, in terms of reliability, etc. Picture quality is a subjective thing. Get which ever brand that looks best to you. It's your money.
