The simplest method for a tv samsung reset is through the Settings menu. Press Home, and then select Settings > General & Privacy > Reset from the remote. Type in the PIN and confirm the reset. The TV will turn on and reset to its factory settings. This is helpful to troubleshoot technical problems, to clear data that has been saved or to get the device ready for resale. You'll have to reconnect to Wi-Fi again after the reset, and set up your preferred preferences once more.
