a vertical thin red line on my screen

[zoran]

I have a thin vertical red line crossing my MBPros screen from top to bottom. When i make a screenshot it is not viewable, might it be burned pixels?

has something to do with graphics - either gpu, cable connecting to the lcd, or the inverter. don't think the lcd would cause that, but that's a possibility as well.

How can i check and where can i start from?

Which MBP do you have? 15" or 13"? and year model?

Its the 15" 2.4Ghz Core2Duo (silver buttons)

That's a 2008 machine or older, its had a good run

That year only has one graphics card, the GT 8600M. In 2009 they put 2 graphics card, to save energy! But the advantage is that if one card burns or starts causing problems, you can switch between them! I own a 2010 MBP and the intel graphics doesn't work that well so I have it using the dedicated.

I wanted to see if we can change the graphics card and see if it's the screen or the chip! I think it's either the cable or the graphics chip!

I wouldn't say one can just switch between the GPU's if one burns out. Ask any 2010 or 2011 MBP user with a dead dedicated GPU (myself included). Generally the system will do a self test on boot up which results in a fault start due to the dead AMD/Nvidia GPU chip.

well his graphics isnt completely burnt (if the red line is due to the graphics), so if he starts up his computer, the graphics wont give an issue and he can switch by either turning off switching which will force the computer to use dedicated or he can download the FXgraphics apps and do it manually there.

The Nvidia 8600GT is known for failure. However I don't think that it is the case this time.

My suspicion is either a bad connection or a failing display.

That said, it's an early '08 machine, and something else will probably break on it soon.
