The SD card reader obviously knows something happens when I put a micro SD card in I get the black screen message to remove the card and power off.
I replaced the SD card reader board with one from amazon, still acts exactly the same. I don’t have a microscope but I was eventually able to continuity test from the test points before the SD card board connector to the pins at the rear of the SD card reader using the pinout on here and everything is connected as expected, but I still get the same behavior as before.
What do I check next to figure out why the SD card reader doesn’t work?
Thank you
