Fail to init Emmc

Greetings to all
buy a used nintendo swith with the problem that does not turn on
I measured the capacitors and none are in short
load at 5 volts and 0.40 amps
I realized that it is only in rcm mode
in Hekate it shows “failt to init eemc”
any idea how to fix?
I use google translator, sorry

looks to me like the emmc is faulty and you can’t do much. Are you able to make a Nand backup or get the prod keys?

I would open it up and check for any damage or corrosion on the emmc or the connector to start with.
