I was able to pull it apart and disconnect and reconnect the cable and I still have banding. Not the hardest machine to work on (the 27 inch iMac is worse) but I did feel like a giant poking around the pandora's innards. The cable looks fine so I suspect the LCD is bad.
And thanks again for...
Linux-SWAT, I'm in Baltimore, Maryland, USA. (the nicer part of it, not the part featured in HBO's "The Wire"). T.T., unfortunately the banding is persistent regardless of screen tilt, it does not change.
Thanks shenmue. Trashymg, you are correct that flashing did not fix the problem. Now, do I need to replace the entire LCD or just the cable? I have no idea, the banding is not consistent with what others report with LCD cable failure.
I noticed a screen anomaly this afternoon. Is this also a cable issue? I had some minor ghosting about a month ago but it was still useable. Not so much anymore.
