after a weird route for my shimian to set on my desktop (FedEx)
At last I have it!
As far as I can see: no dead/stuck pixels
But there are yellow tint on the bottom of the screen
I know it's common problem (even on Apple cinema display), so I searched google about this problem and found something interesting on another forum

What Could Be Wrong?
The same reader who tested the colour temperatures of his yellow iMac display last week – and coincidentally fixed his jaundiced iMac without knowing how he did it – thinks he may have figured out the issue:
I now am fairly certain that the yellowing of the display is a manufacturing defect involving the distance between a layer of material used to diffuse the LED backlight and the LCD panel. To show a perfectly even colour, this light scattering panel has to be absolutely flat and free of any warping, kinking, or thickness defects. It is this layer that I believe is at fault, and causes the colour to drift and give the perception of yellow stripes, fields, and corners.
This would be absolutely consistent with the reports of horizontal and vertical stripes (a vertical or horizontal kink) or corners (a bad tuck). I believe these defects may not appear in the factory. Rather, with the rough handling the monitors receive when shipped this layer gets knocked out of alignment.
It also explains why my careful assembly and dis-assembly resulted in the yellowing disappearing. By being cautious, I basically returned the monitors to the original factory state of perfect alignment.
so.. I'm curious if this careful assembly and dis-assembly
will cure the yellowing tint of my monitor
I'm not in rush, but I hope I can fix it by myself rather than retuning it to korea!
The problem is that I don't have the experience for this task and afraid of something goes wrong, so I just want to share my findings here to someone who have this problem and he know how to open the monitor in the proper way so he can make some tutorial for all of us..
