Answer to "LCD with red and green colour only."I crack this device twice like this, lost blue on screen, but both time recover fortunately. It seems that some ribbon cable do loosen after cracked. First time I accidentally crack it again, and it come back to normal. Second time I shutdown it and bend it on the back slightly, and it does come back normal. This is not a good way to fix, but you can try it if you have nothing to lose.
