I wouldn't recommend voiding your warranty by cracking it open.
The margin for error/causing damage is high.
With that said... ChrisPyzut has opened his up.
He was going to take another look this weekend.
If I understood him correctly he said the light bleed would appear to be related to the amount of pressure applied (or lack of) at the edge of the screen.
Hopefully he reports back in with some pretty pictures.
I have heard this sort of talk with pretty much every monitor, bits of paper in gaps, moving the frame etc etc. at the end of the day you probably cannot do anything about it, because it is the panel, not other parts pressing on it.
