Hello, WhatJB !


This is possibly a video card gone bad, and a lesser possibility is the logic board. In either event, the repair will not be inexpensive, so your decision is : do I want to fix it? That depends on factors like age of the Mac, processor, memory, hard drive size, for what the Mac is used, et cetera. I don't think we can definitively answer those for you.


For exact pricing on the repair, you can turn to Apple directly or an Apple Authorized Service Provider.


Have a great day!
