820-00045-A glitching

[MaxFix]

Hi everybody,

I have a strange case with 820-00045-A MacBook.
No water damage. No drop damage. Just out of blue.
2 out of 10 works normally, boots to OS and stable flight for hours.
5 out of 10 doesn't want to turn on at all.
3 out of 10 tries to boot but gets stuck with this glitch on the screen (please check photo). Any clue what that can be?

Thanks!

Looks like RAM, or CPU issue.
You can try to reflow them, or put entire board into IR oven.
Use only quality flux...

Dead CPU as all A1534s have

Thanks for the info guys!

This guy (who is good by the way) did reball the CPU and fix the SSD issue from the same board: https://www.youtube.com/watch?v=CM5iKCi8_UQ&t=299s

I guess it worth a try.

If it was reballed for a cracked ball, maybe, but if not, he's just heating a dead chip that will die again.
