MacBook Pro kernel panics when using internal display

A family member gave me this MacBook Pro so I could swap the screen on to my personal machine. He a bought this machine in 2016 for his photography business, he tells me one day a camera fell onto the MacBook's keyboard and immediately killed the entire machine.

When I first got the machine I tried turning it on but it just beeped 3 times (usually means RAM failure but I've seen it occur in machines with dead GPUs, since this Mac has soldered RAM it's really difficult to test different hardware), I swapped the display and forgot about it. Some time after I decided to charge the laptop just in case the battery was still functional, suddenly it chimed! But as soon as I opened the lid it died showing all kinds of graphical artifacts.

Trying to power on the machine in clamshell mode is also useless as for some reason the artifacts are transferred to the external display and the machine just restarts. The only way I've got the Mac to work is by plugin all the external peripherals I need and the charger, turn it on, close the lid, and then connect the HDMI cable for the external display. Following this method the Mac is very stable, even when the CPU and RAM are under heavy loads, I even managed to edit a 1080p video with Final Cut.

It seems that the MacBook refuses to work with the display that was plugged in when it was powered on, but any additional ones work without issue.

Even after constant crashes I've only managed to recover one of the error reports that the computer generates after each kernel panic:

mp_kdp_enter() timed-out on cpu 0, NMI-ing

mp_kdp_enter() NMI pending on cpus: 0 1 2 3

Also Apple Diagnostics returns no errors, except one time it reported a RAM issue. Also tried memtest86 but nothing.

So far this machine has completely stumped me.

Hope someone in this site has any clue to what could be the cause of these issues, thanks in advance.
