| Apr 5, 2020 at 9:53 | comment | added | beta | Thanks for the detailed and helpful instructions. Currently I was doing the analysis with the back cover off. So does that rule out your hypothesis of wrong assembly being the cause, right? | |
| Apr 5, 2020 at 3:10 | comment | added | Allan | This sounds like a faulty reassembly - specifically long screws into short holes. I've seen this before. If you're not careful, you can "push" the logic board against the case causing shorts. Disassemble again, and put in only the minimal number of screws to hold things in - two or three should be enough. Run without putting the back cover back on. See if the problem goes away. I would also look for "extra parts" (you know, the extra parts you always end up when fixing something). You could have something loose in there mucking things up. | |

| Apr 4, 2020 at 19:50 | comment | added | beta | Thanks for your comment. I explained that I reduced the possibility of a faulty RAM, didn't I? First, I removed one RAM stick and booted which resulted in the same erroneous behavior. Then, I removed the other RAM stick (and put back the first one), which resulted in the same behavior. So it should be certain that the RAM is not faulty. It could be that both RAM sticks are faulty, but I think the probability is extremely low. | |

If you are sure that you want to repair it, I would start by finding somebody with the same Macbook and swap the RAM to see if that's the issue. I don't think that this is the most likely issue but you need to exclude the possibility of a faulty RAM before replacing the motherboard. | |
