The screen on my 2007 iMac started to show vertical lines in 2010 and by 2012, the whole screen was covered and you couldn’t see anything. Even the additional monitor I attached was blank... Do you know what this is and is there a fix? Thank you!
Thanks for the post!
Just to start off, this machine has no financial value, so it’s not worth putting money into unless you are a repair hobbyist, etc.
If you could supply the serial so I can determine the exact model, that would help. Lines on the screen generally indicate a damaged screen, but the way you describe it has characteristics of a bad graphics processor (no external video). Many iMacs do have replaceable video cards that tend to go bad, but I don’t think the 2007s did. With the serial I can determine if it’s a model that is prone to GOU issues. If the lines are in a specific place, that usually indicates a bad screen, but if they are scattered consistently across the screen, that’s GPU territory.
But again, if it’s really a 2007, you’re better off picking up a newer iMac for $100 than putting money into it.
