Hello. I got a 820-00281 board that looks very clean.I do not find any damage on the board at all. This macbook turns on, but will not boot to anything. When I try to start normally, it boots maybe about 40% and then turns off. If I hold the option key, The internal SSD does show up and if I try to boot into a Catalina installer, it makes it to the part where the grey background shows up on the installation screen, but then the computer turns off again. Same thing if you try and boot to USB copy of OSX. I was able to run diagnostic on this and it fails with error PPM002 "There may be an issue with a memory module". I then booted the board using a USB stick with memtest on it and ran the test and that also seems to fail. It stopped at 90% of the test with only 33% pass and over 10,000 errors. Sounds like a memory issue so would you recommend trying to reflow the ram chips or something else?
