I have no idea what's exactly problem of my iMac 27 2009 late
I cna't figure out the vertical line on the screen
There are so many different reason causing it
Some people say : LCD Display or Graphic card or LCD Display Logic Board .
So could anyone tell me the correct solution ?
iPhone 5, iOS 7
It's impossible to say exactly what the problem just by looking at an image.
You can rule out a hardware issue by running the Apple Hardware Test > Using Apple Hardware Test
Thank you for your advice
But i send it to local Apple Authorized Service Store
Then they did it what you say .
It shows the Display panel problem .
The points is that i replace the display screen .But with the old Display Logic Board .
That didn't solve it .
Could it be possibility not working with the Display Logic Board failure ?
I Have the same problem with my Late 2009 iMac.
How did you solve this issue?
Thanks in advance,
Stefan
