Actually, how do you know got dead pixels? How to check? Pixels quite small right?

Ooooo.. ok, ok, thanks, better check mine then! Are there many dead pixel cases out there? Usually it is manufacurer's fault or due to garang usage?

calibration is at the main menu (accessible without putting any game cartridge - mm... sounds familiar? ;p). though the default setting should be good enuf.

Colinwong's recommended download is a pretty good diagnostic tool too (thanks colin!)

other than that, just check the physical aspects la, like buttons, hinges, scrathes, etc. Should be ok la, free some more what!
