If the screen on your Retina 15" MacBook A1398 is randomly turning black or the MacBook sounds like it is turning on but nothing appears on the screen, it may be suffering from a common graphics issue.
The Fault:
The issue is very commonly misdiagnosed as a faulty graphics chip or GPU and some shops will go about 'heat gunning' the chip trying to 'reflow' it.
The NVIDIA GeForce GT 650M chip is actually extremely reliable, the issue is actually with its power chip.
The power chip is normally badly soldered from the factory and its location on the back of the GPU only exacerbates the solder joints causing them to crack and fail.
Apple recognised this as a manufacturing fault and offered replacement logic boards for many years after original purchase. Their repair was to swap the logic board like for like with the addition of a small patch of rubber on top of the Graphics power chip (maybe to dampen shock - who knows?). This program has now ended.
