Remote's power button doesn't turn the device on or off

A dead power button specifically is usually wear on that one button or a device-side standby issue, not the whole remote failing.

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

  1. Unplug the device for 30 seconds to fully power-cycle it, then try the remote again.
  2. Test whether other buttons still work normally to confirm the issue is isolated to power.
  3. Use a phone camera to check if the remote's IR light flashes specifically when pressing power.
  4. If it flashes but the device doesn't respond, temporarily disable HDMI-CEC settings and retest.
  5. Clean under the power button following general sticky-button cleaning steps.
  6. 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.

When to call a pro

Not typically needed; a confirmed dead power button after cleaning is most efficiently solved by replacing the remote.
