^^^ I have a band like that in the exact same position and it also took a couple of years to show itself. Guess it's a flaw in the panels themselves that only shows up after extended use. This is better than the immediately-noticeable-since-day-one banding on many Sharp HDTV's (at least we got a couple of years of band-free viewing out of the 747i) but it's not going to get better. Mine hasn't, I've just learned to live with the 'bands' (a few more have crept over the past year or so) and passing time until a truly astounding HDTV makes me want to buy it as badly as I wanted the 747i back in '07.
jasep, since you bought the set with an AMEX you doubled your manufacturer's warranty an extra year, which expires summer of 2010. You have until the exact date you purchased the set in '08 to explore alternatives. Call AMEX, call whoever sold you the 747i NOW
and start exploring alternatives. Best case scenario? There's a dealer somewhere that AMEX will re-imburse for fixing the panel because it's under the card's expanded warranty. Even better case scenario? Since Olevia went under and there's no manufacturer to support the product AMEX might agree to finance a replacement TV for the value of what you paid for the 747i back in '08 (i.e. new TV!
). Worst case scenario? Neither AMEX or anyone moves a finger to help you (because of Olevia's trail of fraud and lack of parts/qualified repairmen) and you're stuck with a 747i that still puts a pretty SD/HD picture, but with small bands beginning to appear slowly over the next few months. Get on the horn with AMEX and whoever you purchased your set from (after you check your credit card statement and receipt to check the date by which all of these dealings must be done) RIGHT NOW
and don't forget to mention that you doubled your manufacturer's warranty on the purchased electronic product by an extra year.
Good luck, and don't hate the 747i for having a defect none of us knew was there until we got a lot of mileage out of the purchase.
