![]() You can replace the chip but it'll die again in a few years, these quad core sandy bridges married to the same heatsink as a junky AMD GPU are trash. If you have a Macbook Pro with an AMD GPU - it is about to die or has died already. While not worth fixing, it is at least fixable. If you have a Macbook Pro with GeForce 8600M graphics, it is probably dead already. If you have an X1600 based iMac or Macbook Pro from 2006-2007, the GPU is probably already dead, or died 3 times already. Most of the time this issue is screen or GPU related. If you see lines only with photobooth off, intel integrated graphics is bad. If you see lines only with photobooth on, discrete GPU is bad. photo booth turns the integrated GPU off, and discrete GPU on. Try this if you have a machine with integrated graphics + discrete GPU. Reballing is also BS because the GPU is DEAD!!!! Putting new solder balls on a DEAD GPU does nothing, you are just heating up the dead chip to make it work again, similar to how poking a recently killed bug causes it to move a little until it stops. One person says the cable fixed their problem so 100 other people buy an LVDS cable only to realize that wasn't their issue, but since they never come back to the thread to say it was not the issue, no one ever knows. The idea that the video cable causes this is a myth that has been perpretrated for years by wishful thinking types because they want a ten dollar fix to their problem. This issue is almost, 99% of the time, never the cable. ![]() I have no idea what that component is, but it's been working perfectly for a few hours now with the bottom replaced so I don't think it was a heat problem / fan problem / graphics card problem / logic board problem. ![]() I LOOSENED them about 1/16th of a turn - Just those two little Phillips Head screws.įixed. I screwed it tighter and they didn't go away after a reboot. ![]() When I touched that, the lines went away. Not much identification as far as letters or numbers. It's about the size of an American Quarter and has a screw at the top left and bottom right. There is a component that is a black square just to the left of the right side fan when looking at the bottom. This makes no sense, but I took the bottom off with an electronics screwdriver and touched around a bit. That told me something was loose or coming disconnected. ![]() I knew if I pushed on the indentation just south of the space bar or below the Option / Control / Command keys it went away. I was NOT about to give it to a Genius for a $500 fix. I had the same problem with a 2008 17" unibody MBP. ![]()
