Macbook Pro 2016, shuts down when moved

This started today, and it scares the hell out of me. I thought the shutdowns were random, but I can easily trigger one by just moving the macbook.

They aren't quite shutdowns: the screen goes black, sometimes the leyboard backlight is still on, and the fans sometimes spin up in the dark state. It happened with a video in the background, which stopped.

I had this macbook in repair last year (liquid damage) and they replaced the entire top cover + fan. It wasn't cheap. Does anyone know if there is anything that can be causing this, that does not require an apple "genius" to fix.

P.S. I'm stuck in Armenia, which is at war, and it doesn't have a single AASP. I can't leave the country, I have to work, and I need this machine to work, so in a bit of a pickle.

P. P. S. Resetting the PRAM and SMC (in any conceivable order several times) did not seem to work.

Solution 1:

It turned out to be a hardware issue. One of the connectors was loose. It’s the rossmann group details what exactly happens: briefly it’s the connector near the hinge of the laptop that causes a BSOD, by (I think) sending the LCD power rail straight to the CPU and tripping the protection features. I strongly advise anyone with this issue to promptly fix it, possibly by sending it for service (they won’t replace the LB, just the cable and that’s reasonably priced).

After fixing - no issues whatsoever.
