I’m sorry for my bad English.
Today I found a solder bridge on two capacitor above the mt ic chip. I fixed it and now when I put the charger in I measure 5.22 Volt and 1.22 amps.
Still nothing on the screen.
With a phone charger in there is a lot of heat on the silver shield and on the Usb-C port.
I think the USB port has been replaced from the previous owner.
With the official charger still nothing on the screen, and the components are cold.
I don’t know if the original charger is working properly because I haven’t another switch.
