suddenly my screen color changed to negative/black on white. but when i inverted the screen did not back to normal quality. the trace or shadows remains when i move the window. when i log out it turns again to negative form. and when i log in it seems back to normal. but it does not have the same quality and sharpness.
what is this problem? is it relted to display cable?
Try Reset PRAM. http://support.apple.com/kb/PH4405
Try Reset SMC. http://support.apple.com/kb/HT3964
Is it possible that you can take the MBP to the Apple store for checking the MBP out?
Best.
thank you for reply.
I try reset SMC but nothing changed.
Why I can not reset PRAM? I hold down the command option P R key as the instruction said. But It does not function and MBP goes to utility pane.
at the login I can notice some lighter vertical rectangle part on screen display (i think 4 vertical rectangle)
unfortunately it is not possible for me to take my MBP to Apple Store at this present time.
Make sure that you don't have "Invert Colors" on in "Accessibility">Displays.

i could reset PRAM finally. But it did not solve my problem!
when MBP went to hardware test the screen was orange!
no i don't have invert colors.
System Preference > Universal Access > Seeing > Display
Is the box for Use grayscale checked? If so uncheck it.
Yellow tinted display?
If possible take the MBP to the Apple store. They will be able to help you.
Yes it is uncheck.
I dont see yellow.
Is this problem could be from display data cable?
I've searched some image for yellow tinted display.
Yes! It seems similiar (not completely the same yellow tinted) problem.
screen changed to negative and does not get normal
