Check both ends of the connection
CEC is a control relationship between connected devices, so first look for the television manufacturer’s CEC setting as well as the Formuler setting. Television brands can use their own menu terminology. Use the television manual for that part of the setup instead of assuming that a label on the box controls the display automatically. Begin with the actual HDMI connection you intend to keep.
Enable only the functions you want
Formuler’s instructions identify CEC options for linked power and television-remote control, with settings routes that vary by model. Make a note of the starting state, then enable a single useful function first. For example, test remote navigation before deciding whether the box should also power on or off with the television. This gives each change a clear expected outcome.
Watch for unintended power changes
If the box turns off when another household member changes the television state, examine the linked-power choices before treating the event as a playback failure. Repeat the same action with the relevant option changed and observe whether the result follows that setting. Keep the original remote available while testing; it gives you a way back into the box settings if television-remote control is not behaving as expected.
Separate control from picture and sound
A television remote successfully moving a menu confirms a control path, not a particular video resolution or audio format. Likewise, a picture appearing does not prove CEC is enabled. Record control, picture and sound results separately when describing the setup. If an intermediary receiver or switch is involved, identify it in the report so the complete connection chain is clear to the person helping.
Questions, answered
Can I keep remote control but disable linked power?
Look at the individual CEC options offered on your model. The manufacturer describes control and power choices separately, so test the wanted behaviour rather than treating CEC as one guaranteed all-or-nothing result.
