Bendgate or Stagelight issue in MBP Touchbar 15 2018 Model

Did you review the two iFixit articles on FlexGate?

What I can tell you is the design issue was resolved!

But, there are other conditions which could be what you are facing! Let me explain...

The way the cables are routed and how they are protected does make them a bit exposed either a good bang along the black clutch cover can dig into the ribbon cable or leaving a paper clip along the top edge of uppercase just above the keyboard damaging the displays chin name plate which is a thin piece of glass causing the sharp shard to cut the ribbon cable just underneath when the lid is closed.

So inspect your system for a ding along the black plastic or a crack in the chin name plate.

I've seen a few of these, this is beyond the original design failure. One could argue these two issues could have been prevented by better design, there is a limit on what the hardware makers can be expected to consider in their products. These are both what I would call edge cases as it's not expected people would bang or forget something when closing the lid on it.

The butterfly keyboard is another design failure which Apple took too long to acknowledge and trying to patch it up wasted time and cost a lot of people.

Even-though Apple has offered a support program it shouldn't have come to that! And now people who had gotten the first models 2016/17 can't even get them repaired at a reasonable cost due to the what the system was designed as the keyboard is riveted to the uppercase so its not even easily replaceable alone and Apple only sell's the full uppercase assembly which is quite expensive $400 when a $30 part is only needed! That is bad design! When a physically active part is not replaceable: Port Connectors, Fan's, Hinges, Keyboards, or Trackpads. The last four being the most important!
