3rd times a charm

Where do I start. Bought this as a black friday door buster at Sears for $1000. First one turned on and right back off, twice and wouldn't turn back on. Called Sharp, and they were going to see about sending someone out and get back to me. Called Sears, bring it in, have a new one on Monday. Of course I'll take new over fixed. Go to pick up 2nd one on Monday and the guys bringing it out, dropped it slightly on the dolly..not sure if that lead to the problem I had of a line extending from bottom to 6 inches from top, about 5 inches in from the left side of a blue/green line that looked like a column of dead pixels. Ok, call Sears again, they send someone out to look at it, he doesn't know what to do, no more new ones coming soon. Have to get back to me. I get a call a few days later, someone is comign to fix it..here it was Sharp's guy coming, and I didn't know, since they never did get back to me as promised. Long story short, they shipped me a new one, and so far, so good, but you want proof Sharp doesn't stand behind this TV, try searching for this model number for specs on their site, and even try listing all their TV model numbers...this one doesn't show up. All I can find isthe manual.
