Symptoms

You might notice one or more of the following symptoms:

• The TV turns on briefly and then shuts off.
• The Samsung logo appears repeatedly on the screen.
• The TV remains black and unresponsive.
• The remote does not seem to control the TV.

Quick checks

Before diving into more detailed troubleshooting, try these quick checks:

• Ensure the power outlet is functional by testing it with another device.
• Check if the power cable is securely connected to both the TV and the wall outlet.
• Look for any visible damage to the power cable.
• Confirm that the TV is not in a power-saving mode or sleep timer.

Step-by-step fix

1. Power Cycle the TV: Unplug the TV from the wall outlet. Wait for at least 30 seconds, then plug it back in and try turning it on.
2. Inspect the Power Cable: Make sure the power cable is not damaged. If it is, consider replacing it.
3. Check Remote Control: Replace the batteries in your remote. If the remote still doesn’t work, try using the power button on the TV itself.

5. Reset the TV: If the TV turns on, navigate to Settings > General > Reset. Follow the prompts to reset the TV to factory settings. Note that this will erase your settings and preferences.
6. Update Firmware: If the TV is operational, check for software updates by going to Settings > Support > Software Update.
