Just was looking for some clarification and definition of my problem with my Sharp.
I have a Sharp LC-32DA5U which is under extended warranty at The Brick in Canada (don't shop for anything there...they will totally screw you). I am sure this isn't the same issue as banding and I think it is called "pillaring" but I just wanted some clarification if you'd be so kind. (pic below)
The problem occurs on similar background as many people list for their banding tests, however the problem ONLY occurs on the HDMI input, so I am pretty sure this isn't banding as it isn't related to the backlight or the glass.
I am being told that it is a compatibility issue and that it isn't covered under my extended warranty...problem is that the TV is the compatibility problem...it doesn't work with ANY HDMI device connected to it (I have tried over 10). They all exhibit the same issue. I was also able to reproduce the exact same problem on the 32" Aquos model that came directly after mine...so clearly it is a problem with Sharp's HDMI decoding or something like that.
You should see 3 sets of two lines vertically down the length of the TV. They are darker than the rest of the background. The mouse pointer is between two sets of lines. Can someone let me know what this problem might be called and if there is any possible solution for it. (tried a zillion cables and many, many different HDMI devices...all look the same).
Thanks for your time and input.
