Defective Screen

The screen was sent back home to China. I didn't notice right away that it was defective. It's not seen on backgrounds with colour but on white background it's quite clearly seen that the left part of the screen is of different shade than the right one. While the right half is white as it's supposed to be, the left one is slightly greenish and it bothers me so much when I try to read. I contacted the seller which said that it's ok to replce it. So in couple of weeks I'll have my PDA back with normal screen I hope.
