Samsung TV - Factory reset and self diagnosis tools

When you are having a problem with your TV, you may want to just do a factory reset and start over. The good news is that even though this is possible, it may not be necessary. Your TV also has several self diagnosis tools built-in that can help you solve any problems you are experiencing with signal, network, picture, or sound.

Note: The provided information refers to Samsung Smart TVs sold in Canada. The available settings and options may differ for devices sold in other countries. If the steps do not match your TV, visit our Support Center to find your TV's user manual.

Want a complete do-over? You can restore all TV settings (excluding the network settings) to their factory defaults.

  1. Navigate to and open Settings, and then select General


  2. Select Reset, and then enter your PIN (0000 is the default). 


  3. Select Reset again, and your TV will restart automatically. On some models, you may be asked to confirm your decision by selecting Yes to complete the reset.
