On my MacBook Pro 17", the screen shows some unwanted lines. Its graphics card is not GeForce 8600.
Will it be alright if I apply thermal paste on the graphic heat sink? Would that remove the unwanted lines? If yes, how do I get to the heat sink? If that doesn't work, then is there another alternative to fix the problem? Â
Thanks ahead for the help.Â
[Macbook] Thinking of applying thermal paste on heatsink to resolve display issue
Don't even think of messing with the graphics card. There are other reasons too for this problem but their solution is not what you are saying.

Thermal paste is not something to fix problems. It is used as a medium between the heat sink and the processor chip of graphics card or the CPU to transfer heat from one body to another. It has nothing else to do.

In your case, you said you are facing unwanted lines. There might be a possibility that your graphics card is dusty and you need to blow it off using a blower at medium speed. Sometimes the fan rotation gets reduced or low due to a lot of dust on it and it causes the problem.

You can take your laptop back to Apple because they do these kind of things pretty good.
