Do you reckon my internal regulator is faulty ? I used external 5V to Vbus, it's still not responding...??

I can't pinpoint where the fault based on the information provided here.
What is the VTarget/Vtref pin connected to since it's 3.3 volts? It should be the same as the IO voltage, which you measured to be 2.2 volts
Connecting ...
- Connecting via USB to probe/ programmer device 0
- Probe/ Programmer firmware: J-Link ARM V8 compiled Nov 28 2014 13:44:46
- Device "NRF52840_XXAA" selected.
- Target interface speed: 4000 kHz (Fixed)
- VTarget = 3.313V
Hi Vidar,
thanks for the reply,
I'm not sure as well, suddenly our PCA10059 is not responding properly,
I did well before,
Worse care, we need to replace the chip,
We want use external supply and see the response,
Any suggestions ?
Thanks,
Kind regards,
