Ok after following the instructions on your blog I have successfully flashed the v3-5.0.bin?
Screen in powered up and looking stable.
Displaying firmware version 1.17 is that the right one?
Thank you for the help.

I have 5v at the 4 way connector
The 40 way connector is aligned pins all look ok
I have tried powering from a usb but still not working !

Hi purchased the duet WiFi and the PanelDue 5inch which arrived this week, today I setup both to test as per the instructions on the webpage but the PanelDue won’t power on any thoughts as to why ?
