HDMI-CEC isn't working
HDMI-CEC is the standard that lets your Manhattan Aero, TV, soundbar, and other HDMI devices talk to each other. CEC implementation varies by manufacturer, so a few setups need a nudge to get working.
If the Aero turns itself off almost as soon as you turn it on, see Aero turns itself off when you turn it on – that has its own fix.
Quick checks
- Is CEC enabled on the TV? TV brands all use different names for CEC: Anynet+ (Samsung), Bravia Sync (Sony), Simplink (LG), Viera Link (Panasonic), and so on. Check your TV settings and turn it on if it’s off.
- Is CEC enabled on the soundbar or AV receiver? Same check, if you have one in the chain.
- Try different HDMI cables and ports. A spare cable and a different port on the TV often help isolate a basic compatibility issue.
Full HDMI reset
If the basics haven’t helped (the Aero isn’t waking when you switch inputs, no CEC control at all, flickering picture), a full HDMI reset often clears a stuck handshake:
- Disconnect all HDMI cables from the TV, not just the Aero’s
- Unplug the TV from the mains and leave it for a couple of minutes
- Plug the TV back in and reconnect the Aero first
- Test that you can switch to another input and back to the Aero cleanly
- Reconnect any other HDMI devices one at a time
This forces the TV to rebuild the HDMI connections with each device.
Volume buttons not working
If power and input switching work but the Aero remote’s volume buttons don’t control your TV, that’s CEC Volume Control compatibility rather than a fault – some TVs (most notably LG) don’t support CEC volume from external devices.
