Problem Description: So I have a 2.33 Ghz 17" MBP, 3 GB of RAM, Late 2006 model (MA611LL/A). OS is 10.5.6. Upon wake from sleep, I get a wide vertical band on the screen that looks somewhat like: Click here for the full 1680x1050 image. Note that this is not a real screenshot - I edited the band in. (The band does not appear in screenshots.) I don't think it's the dreaded NVidia bug (http://support.apple.com/kb/TS2377) because A: this machine wasn't produced in the correct time period, and B: System Profiler reports my graphics chipset as "ATY,RadeonX1600." Attempted fixes: I thought it might be a software issue, but it persists even after I restart the machine - even during the boot sequence. I've also tried things like creating new ColorSync profiles. etc. Further, the band continues to appear on the laptop's display even if I connect a external monitor and make the external display the primary display. The band eventually fades and usually goes away after a couple of hours, but it's a real distraction in the meantime. Any ideas on where to start? I'm relatively handy and don't mind swapping out the LCD, inverter (high voltages FTW!), or cables, but I'd rather not thrown down $185 for the LCD if the inverter is the problem... Google is not exactly my friend on this one.
