The M Series systems have fewer parks as more of what was in discrete parts is now unitized into a single chip (SoC) and a few dedicated chips (RAM & Flash Storage) as well as the inputs and outputs we need.

The M Series systems have fewer parts as more of what was in discrete parts is now unitized into a single chip (SoC) and a few dedicated chips (RAM & Flash Storage) as well as the inputs and outputs we need.
Here a display issue is an output so while it is not showing an image straight out, it is not the direct cause of the system going into a reboot loop. The fact image is present using a flashlight tells us the video signal is getting to the LCD, only the backlight power is not present so the video can be seen.
So what we have here is a deeper issue within the logic board which is effecting the backlight power. So let’s dig a bit deeper what happened to the system before its current state? Did it get dropped, banged or even sit unused for awhile? Did it face an environmental event get wet or go between cool and hot spaces where condensation could collect (high humidity) did the system encounter a liquid spill or dust storm event?
