[110] Troubleshooting | Picture (quality)/screen A white line appears on the screen. (only models equipped with an OLED panel) Panel refresh automatically runs after the TV has been used for a long period of time to reduce image retention. Panel refresh starts after the TV is turned off and takes about one hour to complete. A white line may be displayed on the screen during the panel refresh. This is not a malfunction of the TV. [111] Troubleshooting | Picture (quality)/screen Panel refresh does not complete. (only models equipped with an OLED panel) Panel refresh works when the room temperature is between 10°C (50°F) and 40°C (104°F). If the room temperature falls outside of this range during the panel refresh, the process does not finish and a message is displayed. If the message is displayed, check the temperature of the room. [112] Troubleshooting Keyboard You cannot operate the current screen after the on-screen keyboard is displayed. To return to operation of the screen behind the on-screen keyboard, press the BACK button on the remote control. [113] Troubleshooting Broadcast reception Check these things first to troubleshoot your TV reception. Block noise or an error message appears and you cannot watch broadcasts. Ghosting or double images appear. 81
