12" MacBook display/graphics issue. Thoughts?

That could be caused by any number of things, including the logic board. Do you see this even when you try to boot in safe mode?

 

I got the same problem since Mojave fresh install. when I open it unplug track board cable display cable reatch everything boot it up it works with low demanding things for a few hours . if I open up iTunes safari and photos the glitch starts over then reboots, I log in glitch comes again.
the MacBook 12 2016 was not used a lot never dropped no damage what so ever.

 

its known common problem in the repair forums. that's what will happen when there isn't a fan to cool the CPU. Apple should recall this crap

 

I have exactly the same issue. I was coming on to put a post for some help.

I've tried just about everything for boot sequencing but I can't get it into Safe Mode and Internet Recovery they both lock up before they make it.

I can load into Mac Os High Sierra but it will then go to this screen in a few seconds.

 

Isn’t this under warranty since Apple did the repair? Just take it back to them.

 

My 2015 MacBook (out of warranty) displays weird effects like coloured lines (and occasionally a huge white fade to edge of screen, like it's a Victorian photograph). It works fine on an external monitor. I'm looking to see if it's a logic board issue.
