When I went over to my Grandparent's house for dinner my Grandmother asked me If I could check her iMac since something looked wrong with it. I go over to the computer and wake it out of sleep mode and sure enough there was a blue line on the screen. I knew it wasnt the OS because it showed during the bootup process. I've tried resetting the PRAM and PMU but to no avail. I searched on many sites but many people who had the problem all said that it eventually got worse and worse until the screen is unreadable. So for now I'm lending my grandparents my MacBook (it was sitting in the closet, so im glad it's getting some use) I'm wondering if this could be solved by reseating the video connector on the logicboard, has anyone else had this problem? (BTW it looks much like this video except there is only one line currently.) Taking it in for repair is out of the question so I may just let them use my MacBook until we get them a new computer around christmas.
