I assume if I haven't noticed banding I don't have it

We have been very pleased with our 52D62U. Have had it for two months with no problems.
My only complains are that the remote is too slow and although we have a cable box we are getting a lot of digital and HD channels thought the analog cable. The digital channels are numbered with the dot system such as 107.2 and if this remote goes bad I have not seen another with the dot.
In talking to Sharp they agreed the only answer would be to buy another from them.
We don't play video games on ours so if that is where you get the banding I wouldn't know anything about it.
