So I have a 233mhx core 2 duo 17" MBP that I inherited (for free) because of video issues. The problem is that once in a while, like every couple days, the video on the LCD becomes scrambled. All the while, video output via the external DVI port is fine. If I press firmly on the bottom of the laptop, just behind where the battery is, the display goes instantly back to normal. So what I am figuring is that the culprit is a loose internal video cable. I took the MBP apart and on gross inspection, there appears to be nothing wrong with the cable. I should have taken some pictures, but does anybody experienced in supporting these have any ideas about how to secure the cable more firmly? I did not detach the cable in fears of making a tolerable problem worse. The cable appears to have some sort of special translucent tape over it, securing it to the motherboard, as do many of the other connectors. Would greatly appreciate some advice. When I took it to the genius bar, they wanted to charge me something astronomical just to look at it, and like a grand if they need to replace the whole LCD (unnecessary IMHO). The thing is out of warranty. thanks, shellac.
