🔴 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.
🧱 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 it’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 hasn’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 won’t turn on: Continue below.
🔁 Power Cycle the TV
- Unplug the TV from the wall.
- Press and hold the TV’s Power button (not the remote) for at least 15–30 seconds.
- Wait another 30 seconds.
- Plug the TV back in and try turning it on.
🔋 Power Cycle the Remote
- Remove the batteries from the remote.
- Press and hold the remote’s Power button for 30 seconds.

🔌 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.
⚙️ 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.
☎️ When to Request Service
- If the standby light never comes on, even after trying different outlets and cables.
- If the TV doesn’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.
