Switch freeze with sd card

Hi Guys,
i have a strange problem with a OLED. Ebay seller built in a picofly a sell it to my customer.
It works without problems, but since 2 days, the sd card wont recognized by the switch.
Got the tablet on my desk and remove the chip first. Clean all the mess from the modder, and retry to read the sd card in ofw.

  1. If i try to insert the sd card - system freeze immediately
  2. If i try to start with sd card, the switch stuck at Nintendo Logo
  3. Without sd card, system works fine.
  4. X Test with good known cartreader, same isse.
  5. Replace to cap/induktor because they have both gnd. Same issue.
  6. All Pins of the cartreader are solid. No dust or something in the port.

what diode reading on your sd slot without battery or sd card?

I’m having the exact same issue with my Switch V2. From all my research online and troubleshooting, it’s either a damaged motherboard or the modchip died.
