Bad news guys. A couple of weeks ago I started noticing something that appeared to be banding on the right side of my 747i. I noticed it because it started to be visible to me during some programming (mostly outdoor stuff or shots with lots of sky/ocean) but I decided to wait a couple of weeks to make sure. Now its official: my 747i has developed, after 14 months of steady use (95% of it at Medium setting), some 'banding' on the right side of the screen!
In the two weeks since I noticed the banding its become a little more pronounced, enough that I can now see it in golf events or even movies (like "The Fly" on Blu-ray, a flick set mostly in dark interiors) whenever the camera pans from side to side. I'm not a videophile that demands 100% screen perfection (and understand that LCD technology has its shortcomings) but knowing the line of banding is there has become an intermitent distraction. Here's a pic I took of the PS3 game "Heavenly Sword" that shows the right banding at its most visible (camera moving and the background a certain shade of gray):
By contrast here's what my 747i looked like in March of '07 when I took a picture of a gray screen to see if I had banding as bad as the Sharp LCD's from that era:
The only potential cause for this new banding is that about two months ago I decided to start watching/playing SD material in 4x3 square mode again after going almost a year stretching SD material to fit the entire screen. So maybe that right band is caused by the line where a 4x3 image is black (or gray in my case) and leaves an imprint on plasmas. What makes me question this being the cause of the new band is that the left side of my Olevia 747i hasn't developed any banding even though both sides of the screen experienced the borders of 4x3 material. I'm going to start running SD material stretched again to see if this takes/minimizes away the banding on the right side, but it could take weeks (or never) for the banding to go away or disipate.
A friend came over to visit and he didn't notice the banding line until I pointed it to him, and even then he said I was making a big deal. While I agree that the deficiency is mostly in my head (the 747i remains a good deal and still performs as good as advertised) I'm worried that this banding showed up a little over a year after I purchased the 747i. I can live with the one line of banding on the right, but what if another line shows up on the left? And another? And another? While I've always championed the 747i as an excellent HDTV my enthusiasm has been dampened a little by this sudden flaw I didn't see coming... literally!
