Hypno does not boot up properly/Composite out problems

Got my Hypno (Pi4 version) brand new today. Unfortunately it does not boot up properly when connected via. AV breakout cable. I changed the
Lines in the config.txt and added the video=Composite-1:720x576@50ie in cmdline.txt

Still the lights of the hypno stay off when i connect it to power and the av output shows the output shown in this video: WhatsApp Video 2024-05-13 at 16.35.15.mp4 - Google Drive
and then stays dark.

what should i do? :frowning:
