Hi mate don’t you hdmi. From formuler to av then another hdmi. Out of av to the tv
Den123 - You're right:
HDMI from Z8 to AV box.
HDMI cable from AV box to TV.
Speaker cables from AV box to speakers.
The issue is that this setup worked fine before the update but not any more. I thought that the blank screen was a dead Z8 but thankfully it works ok if HDMI cable goes directly from Z8 to TV.
