Hi Matt,

Thanks for getting back to me.

Leaving the box powered off and reconnecting after a while doesn’t seem to have any effect.

I have discovered that you do need to hold the power button for a few seconds to power off.

Any ideas?

Thanks

needing to hold the power button a few seconds highly suggests that the box isn't bricked (since if it failed to reach the bootloader, it would power off immediately), just that there's an issue with the video output / HDMI handshaking etc. Have you tried a different display or cable?
