I have a MacBookPro4,1, 2.4GHz from March 2008. I use my MB Pro with an external display (a Dell 20.1" LCD monitor), i usually switch between this monitor and my Sony LCD screen. I use a DVI cable to connect to the monitor and the tv. Now, all of a sudden it shows the picture as clear as it always has but with a blue "tint". Basicly the image sent to the external monitor is blueish. My best guess is that the red channel in the dvi port is broken or damaged in some way. Anyone ever experienced a simular problem or have a suggestion to how i could replace my DVI port in the computer Thanks for the help!
