I woke my 2014 27" iMac this afternoon and it opened with a screen full of one inch wide blue vertical lines. I shut it down and waited five minutes and tried to start it again...when it opened it was displaying only one, one inch, blue vertical line in the center of the screen. Where to go from here? Appreciate any wisdom that you may have to offer.
Lplug in an external monitor to eliminate a bad screen as the culprit. Do you have a recent Time Machine backup?
That model has removable RAM, it would be worth reseating (remove and reinstall) the RAM.
I have a MacBook pro, will that work as an external monitor for that test? I do have a recent backup but I do not use Time Machine. It is on a external hard drive and has a bootable disk. Not clear on the proper wordage of that. I recently added memory to the two open slots. So you recommend removing and reinstalling all four of those. Thank you.

No, the MacBook won't work like that. Like me, that port at the bottom is an outie, not an innie.
I'm going to suggest that you unplug that Mac, then remove the new Ram, and try it that way.
ALWAYS unplug! Many Macs keep certain circuits energized, even when off.
If that works, then unplug, exchange the new Ram for old, and try again.
Let us know.

I would call Apple support.
They probably know more about their own computers than anybody here on UHH.
Had to reply to this and I know it doesn't help but...... Are you sure you aren't dreaming ?
I thought that Macs never failed hardware wise ?

My first 27" iMac was really bad. They monitored my crashes for six months and never did solve them. I finally surrendered and tried again by purchasing this machine and then took a hammer to the old machine in my driveway for the sake of a few pictures.
Thank you HarryO! I will get back to you on this.
Repeat the Haiku but substitute Apple IOS
