I have owned the ATS-20+ for a short time, and it has developed a problem... I would be most grateful if anyone has some pointers please?

Upon switch-on, the display shows the boot screen, but goes no further as if there's no battery power.

If I plug in the USB C lead, the radio does the same, but reboots over and over.

Interestingly, if I plug in the Mini-Usb, the radio will switch on and work (whilst plugged in)! The charge indicator still shows 0% though.

In fault condition, I was getting 4.1v at the battery terminals, and 4.2v if the USB-C was connected. With the Mini-Usb connected, I'm getting 3.98v at the battery terminals.

This is the original firmware. Thanks.

Edit:
It almost feels like the nano board isn't getting enough voltage from the battery or usbC on the main board, but does it using the Mini-Usb directly mounted in the nano board.
