The Raspberry Pi Pico (the CPU running the front panel when you plug into the CAT cable) can get power from other pins on the device OR the USB port you plug the computer into. ?A hunch is that since you have measured power on the battery pack, but see nothing on the screen when you apply power to the Zbitx power jack, that there is no power getting from the power connector to the rest of the radio. ?It might be something very simple like a loose or unsoldered connection on the power connector...

Probably good we don't live closer, I would have already been there urging you to open it up...

Best of luck with the Zbitx going forward,
