Hello, just registered here because i have a problem with a V1 Switch SD-Card Reader and need some advice.
When i got the Switch i knew it had problems with the SD-Card reader and changing the SD board didn't solve the problems. Thats when i start measuring in diode mode.. started at the connector and worked my way to the backside of the mainboard. Compared to the 2 pictures i found with values of a working unit all my readings are off around 50 to 100 and there is no 3.3v getting to the SD-Card reader.
What seems odd to me and bugs me is that there should be a 1.8v line which also has 0v. I reflowed the MAX77620A but that didnt help. Fun fact: the console charges and boots up normally.
Maybe someone has had the same issue in the past and has a hint or solution for this problem...
