Hi there,

 
I was asked to repair a USB C connector on a nintendo switch, I screwd it up but now it's ok, all signals do bip when they should.

Battery was dead as the connector was dead for 6 month... I changed it to...

Now it's supposed to work BUT I got this error code 2101-001, that tells absolutely noting.

Configuration :

• device oppened
• SD card slot removed
• battery brand new (voltage checked : 3.7 with device turned "on")
• USB C connector removed, pads repaired (no there is no short)

operation : 

• press power
• nintendo logo appear for 1s
• black screen 2s
• Switch logo appear for 1/2s
• Error code appear... : 2101-001
• after few seconds seconds fan start to turn, the copper heat bridge is hot like I can keep a finger on it but i know it's hot (sorry I lost the thermal camera)
  • press power for 3s ==> juste repeat whats writen above
  • press power for 12s ==> print switch logo and trun off

I dont know were to look chips are ok the thing is turnin ON so voltages may be good too....
Do you have any clue ?
