Troubleshooting • No HDMI output when using Ai Hat+

Hi Team

I have a Rpi 5 (8Gb), official Rpi power supply (5A for 5') and the Ai Hat+.
With the Hat+ connected, I do not get any monitor output - this does not seem to be a power issue (was my first thinking) as I have already tested with a lab power station providing v5.1 to the 5'.
When the Hat+ is connected, everything else works as expected, apart from HDMI.
I'm on the latest 64bit build, have updated and also installed the Hailo dependencies and have also used the NPU for running a few tiny CNN's.

Could someone let me know best place to restart debugging this, I do not see anything untoward in dmesg etc.
