"Sharp has some serious issues to address."1.5 starson by KaneRobot
Pros: Great value, nice looking bezel
Cons: Awful "banding"/uneven backlighting causes darker lines during camera pans, buzzing emits from panel, somewhat limited inputs
Summary: I am now on my second 46" 62u, and unfortunately my second fares no better than my first. I really thought this TV would be outstanding, and at first glance in-store (never a good way to judge a TV) everything is great. However, getting it home and playing stuff on it was a different story.
This panel has some major issues with "banding" (the quotes are used because that may not be technically what it is, but the effect is the same) - essentially, whenever the camera pans up to down or vice-versa, you will see multiple darker horizontal lines appear on the screen. Some people have also reported right to left/left to right vertical "banding," but I have not experienced this. Yes, the stationary picture can be fantastic, but the effect is ruined whenever the camera moves.
The other major issue I've noticed is a buzzing noise emitting from the back of the panel. Now, if you are in an area where there is other noise (PC, people talking, XBox 360, whatever) you may not notice it, but if you are in a quiet room watching a movie, during quiet parts it is very noticeable and very distracting.
Again, this is my second set as I've already exchanged once. I'd expect this quality from a second/third tier brand like Westinghouse, but not from Sharp. Until Sharp addresses these issues, I VERY strongly urge people to NOT purchase this set. Sharp may very well address these issues in the coming months, but as of yet there has been not a peep from them.
You can check around on various popular home theater forums like AVS to read about many people having similar problems. While I have seen a few people satisfied with the 52" model, I've yet to see one single person satisfied with this 46" model.
