How to revive a MacBook?

Question

macbook

Hello.
I have a MacBook Pro 2011 15””.1”, MacOS High Sierra 10.13.6 installed.
After sitting down, it refuses to turn on - after the disappearance of the logo and the download indicator, it hangs on a white screen.
Doesn't respond to Command+R. Apple Hardware Test found no faults.
When loading (on the logo screen and the loading indicator), it gives off green tones, the loading indicator itself has become green. On a white screen, graphics return to normal.
When you try to boot from the installation flash drive, it reaches about 70%, tries to reboot and "forgets" to turn on after that.
What can be, how to treat or should I go to the SC?

Answer 1

Try resetting the SMC, then to the service.
