CEC issue (alien.top)

Hey, my latest and greatest Apple TV is going on bizarre ass tangents randomly acting like it’s possessed when CEC is on. When I turn it off, it’s fine. It’s fast forwarding, turning on, turning off, rewinding, raising the volume, lowering the volume, pausing, playing. It’s almost like it’s stacking every command it gets and then when wherever it stores those commands gets full, it releases them in a flurry. When I completely shut down the device at the power source for 10 minutes. It works, until the next time. Resetting it works for a little bit and then it comes back.

What exactly would cause this? Could it be Bluetooth interference from the television remote? The WiFi 6E AP 15 feet away? I’m perplexed.

HDMI-CEC is a poorly implemented standard. Some devices, especially older ones, don’t play nice together. If it’s not working properly for you just leave it disabled.

You might need to use a process of elimination to figure out what (if any) other device in your HDMI chain is causing the issue. Such as unplugging other devices, connecting the ATV directly to the TV. Or disabling CEC on other devices. I had issues once with my Marantz Receiver when network control was enabled.

Sounds like one of your remotes (not necessarily the ATV one) may have shit the bed. I'd try removing batteries from them one at a time and see if the problem goes away.

First thing I would try is a different HDMI cable, also leave the TV unplugged from power for a little while so it does a fresh boot up.

See if the TV has any updates you can run.

When was the last time you charged the remote?
