Hi Guys, I had a Nintendo switch that wouldn't turn on or charge. The consumption was 0.49mA.
The battery was depleted at 2.5V. Externally charge up to 4.2v. When pressing the power button, it does not start but the SOC/DRAM reach a high temperature.
I have removed USB-connector, M92 and P13. But I still have a short in the capacitors that I indicate in the image, I think they belong to the 3.3v line.
Can you think of more steps I could do?
Thanks for your help!
I will try to do a voltage injection, but I have a hunch that I am going to have the SOC in bad condition!
I think that I will not be able to solve it, I apparently have a short in the SOC.
I have 20ohm impedance on the 3.3v rail.
And injecting 3.3V I have a consumption of 0.9A that is dissipated by the SOC as you can see in the video.
Is there any solution?
Thanks for your help!
