displayed. (only models equipped with an OLED panel) Search Panel refresh automatically runs after the TV has been used for a long period of time to reduce image retention. If the TV is turned on, the AC power cord (mains lead) is unplugged, or the ambient temperature falls outside of the range between 10°C (50°F) and 40°C (104°F) during the panel refresh, the process will not complete and this message will appear. If panel refresh started automatically, it will restart when you turn off the TV with the remote control. If panel refresh was initiated manually, you must select it again. [124] Troubleshooting | Picture (quality)/screen You are concerned about an image retention. (only models equipped with an OLED panel) If the same image is displayed repeatedly or for long periods of time, image retention may occur. To reduce image retention, we recommend that you turn off the TV normally by pressing the power button on the remote control or TV. Note Manually perform panel refresh only when image retention is particularly noticeable. As a reference, perform it only once a year. Avoid performing it more than once a year because it may affect the usable life of the panel. Images that include clocks and bright colors easily cause image retention. Avoid displaying these types of images for long periods of time, otherwise image retention may occur.
