Swapped motherboards between two v1 units. The switch now sometimes boots, the switch was in pretty rough shape so it could be a pre existing issue before swapping. Someone had gone ham and totally destroyed the sd card slot so it’s very possible the motherboard had other damage. I wish I had tested before swapping. I sometimes get the Nintendo logo then black screen where I can see the backlight is on, and other times it boots fine but randomly turns off. It’s not overheating as I’ve swapped paste in many units and never seen this particular issue. Any thoughts or tips are appreciated.
