I developed a vertical yellow line on my mid 2011 iMac - anyone else have this issue.
My iMac developed a vertical yellow line on the left side of the display. Any easy way to tell if it is a logic board or ?. Anyone have idea of cost to repair or if this is a known issue? I have 2 older iMacs that have great displays with no issues. Screen shot shows the line.
iMac (21.5-inch Mid 2011), OS X Mountain Lion (10.8.3), tb drive - 16gb ram
