how do you fix vertical lines in 17" iMac Intelbased
I have an iMac 17" intel based desktop that has 3 flashing vertical lines down the whole screen. I have already gone to calibrate disply in system preferences, but this did not fix the issue. Can someone help me out with the fix to my issue. I am running Snow leopard on this computer.
iMac, Mac OS X (10.6.8)
