How can I stop my smart TV turning itself back on after switching it off?
Disable HDMI-CEC wake and network/mobile remote wake in TV settings, then test each connected HDMI device to identify which one turns it on.
Why this approach makes sense
Identify when the sound happens and isolate one possible source at a time. Pipe, motor and building noises can travel well beyond their point of origin.
Before you try it
Do not dismantle electrical or pressurised systems to diagnose an intermittent noise; record the pattern before seeking repairs.
