RESOLVIDO: Monitor has vertical lines at start-up. - iMac Intel 27" EMC 2546

Monitor has vertical lines at start-up.

At the startup chime the display comes on with these vertical lines. As the boot-up continues the screen color changes indicating the system is running. I accessed the the diagnostic LEDs, all 4 are lit.

Do I need a replacement display or logic board?

Yes, I believe you are correct. The trick in my situation was the external monitor would not actually work unless I disconnected the display panel from the logic board.
