No IO working (Bricked)

Greetings
I’m pretty new to the whole autopilot thing, and on a tight budget.
I have been struggling for days to get my transmitter to get calibrated in Qgc ‘0 channels found error’ (Using a Frsky transmitter and receiver thru a Cuav 8 channel ppm encoder, this setup works 100% on a friend’s Pixhawk)
And the IO leds are lit as follows ( Attached is a photo of leds)
PWR - ORANGE
B/E - SOLID RED
ACT - SOLID BLUE

Is ass if all io are disabled.
I can access the Pixhawk true Qgc and all on board sensors work but can’t seem to add external GPS and Compas. This leads me to think the IO part is ‘Bricked’

All software and firmware up to date

Thanks in advance
