๐Ÿ”ด Check the Standby Light

  • Locate the red standby light at the bottom edge of your TV.
    • If the red light is ON: The TV is receiving power but may be stuck in standby or have another issue.
    • If the red light is OFF: The TV is not getting power.

๐Ÿงฑ Basic Power Checks

If the Standby Light is OFF:

  • Check the power outlet by plugging in another device to confirm it works.
  • Inspect the power cord to ensure itโ€™s firmly connected to both the TV and the wall.
  • Try a different outlet, plugging the TV directly into a wall outlet.
  • Check your circuit breaker to make sure it hasnโ€™t tripped.

If the Standby Light is ON:

  • Try turning on the TV with the remote.
  • If nothing happens, use the physical Power button on the TV itself.
    • If the TV turns on with the physical button: The remote may be faulty. Replace its batteries and try again.
    • If the TV still wonโ€™t turn on: Continue below.

๐Ÿ” Power Cycle the TV

  • Unplug the TV from the wall.
  • Press and hold the TVโ€™s Power button (not the remote) for at least 15โ€“30 seconds.
  • Wait another 30 seconds.
  • Plug the TV back in and try turning it on.

๐Ÿ”‹ Power Cycle the Remote

  • Remove the batteries from the remote.
  • Press and hold the remoteโ€™s Power button for 30 seconds.
  • Insert fresh batteries and try again.

๐Ÿ”Œ Check Connections and Input Sources

  • Ensure all cables (HDMI, power, etc.) are firmly connected.
  • Disconnect all external devices and try turning on the TV.
  • Make sure the TV is set to the correct input/source.

โš™๏ธ Look for Signs of Hardware Issues

  • If you see a faint image with a flashlight, the backlight may have failed.
  • If the standby light blinks or flashes, this can indicate a power supply or main board problem.
  • If you hear clicks or see the standby light flicker, internal components may be damaged.

โ˜Ž๏ธ When to Request Service

  • If the standby light never comes on, even after trying different outlets and cables.
  • If the TV doesnโ€™t respond to the remote or physical button after all steps above.
  • If you suspect a hardware failure (such as a failed backlight, power board, or main board).

Contact a qualified technician for further diagnosis and repair.
