Symptoms
- Every other button works except power
- Have to use the device's physical power button instead
- Power button sometimes works after several presses
- Started after the remote was dropped
Likely causes
- CommonWorn contact under the power button from heavy usePower is often the most-pressed button on any remote and wears first.
- CommonDevice stuck in a state that ignores remote power commandsSome smart TVs/devices need a manual power cycle to start responding to the remote again.
- PossibleHDMI-CEC settings interfering with power commandsCEC misconfiguration can cause a TV remote's power button to behave unpredictably with connected devices.
- PossiblePhysical damage to the button or board from a dropImpact can crack the solder joint or button mechanism specifically at that location.
What to do
- Unplug the device for 30 seconds to fully power-cycle it, then try the remote again.
- Test whether other buttons still work normally to confirm the issue is isolated to power.
- Use a phone camera to check if the remote's IR light flashes specifically when pressing power.
- If it flashes but the device doesn't respond, temporarily disable HDMI-CEC settings and retest.
- Clean under the power button following general sticky-button cleaning steps.
- If the phone camera shows no flash for power only, and cleaning doesn't help, that part of the board has failed and the remote likely needs replacing.
