the last few days, a vertical bar (about 300 pixels wide) has been plaguing my macbook pro screen. sometimes it's solid white, sometimes it flickers in colors, sometimes it disappears! i'm pretty sure it's not a software issue because it's permanently there even right after startup....anybody have any idea what could be going on here ?

that sounds like a broken display to me. I don´t know Mac that well (windows user...) but are you able to test the grafics with an external monitor? I am pretty sure, this is caused by a broken lcd display. Does it look like the picture below? If so, it definitely is a broken display.

I have to agree, it looks broken. I, too, would be interested to see if an external display connected to this machine looked normal. Either way, you're going to need some professional help to fix this.

The problem magically went away, I was away for a few days and now back and it's gone. Very strange. I will still take it to get checked.

It could've simply been a loose connection somewhere. Either way, not a good sign :( – Darth Android Oct 5 '10 at 22:08
If you're still in warranty, better go to apple store and show them that picture above posted by Diskilla. Better do that while in warranty than outside warranty – Enrico Susatyo Feb 3 '11 at 3:48
