Why does an OLED TV run pixel care after it is turned off?

A short compensation or pixel-care cycle after standby can be normal and should not be interrupted. Repeated long cycles, warnings, image loss or a TV that never returns to normal standby should be checked against the exact model.

A short compensation or pixel-care cycle after standby can be normal and should not be interrupted.

First, leave the TV connected to power in normal standby and note the duration and displayed message.

    1. Establish the exact starting state

      Reversible

      Leave the TV connected to power in normal standby and note the duration and displayed message.

    2. Separate the fault or decision boundary

      Reversible

      Distinguish a routine short compensation cycle from a manually initiated long refresh or power fault.

    3. Apply the narrowest correction

      Reversible

      Allow automatic care to complete and avoid running manual pixel refresh repeatedly unless support directs it.

    4. Leave the TV in normal standby and note what appears

      Reversible

      Keep the TV plugged in and in standby and note how long the process lasts and any message it shows. A short compensation cycle is routine, and it should not be cut short by unplugging the TV.

    5. Tell a routine short cycle from a long manual refresh

      Reversible

      A brief automatic pixel care cycle after several hours of use is normal, while a longer manual pixel refresh is something you start yourself. Repeated long cycles or warnings are a different matter.

    6. Let the automatic care finish and avoid unneeded manual refreshes

      Reversible

      Allow the automatic cycle to complete and do not run the manual refresh repeatedly unless the maker advises it. Afterwards, confirm that the TV starts normally, the image looks even and the standby behavior is normal.

    7. Leave the TV plugged in and let it run

      Reversible

      Pixel Refresher does not start unless the TV is plugged in, so unplugging after use prevents the routine from ever finishing.

    8. Do not turn the TV on partway through

      Reversible

      LG says the function stops if the TV is turned on while it is operating, so give it about an hour after a long-use refresh.

    9. Verify before escalating

      Reversible

      Confirm normal startup, image uniformity and standby behavior afterward.

    What LG says

    When Pixel Refresher runs and how long it takes

    The refresh is an automatic panel-care routine on LG OLEDs, and LG documents its triggers.

    Short automatic run
    LG says Pixel Refresher runs automatically when you turn off the TV after watching it for more than four hours in total.
    Long automatic run
    After a total of 2,000 hours or more of viewing (five hours a day for a year), the Pixel Refresher runs automatically and takes about an hour once you turn the TV off.
    What you may see
    During the process you may see some vertical lines on the screen; LG says this is not a malfunction.
    Power and interruption
    The function does not start if the TV is not plugged in, and it stops if the TV is turned on while it is running. A manual run is at Settings, Picture, OLED Panel Setting, Pixel Refresher.

    When this stops being a self-service repair

    • !Check the exact model's guidance if the cycles are repeatedly long, warnings appear, or the TV never returns to normal standby, and contact the maker if they persist.

    Exact questions

    Common questions about “Why does an OLED TV run pixel care after it is turned off?”

    Why does my OLED TV do something after I turn it off?+

    It runs a short pixel compensation or care cycle to keep the panel even. That is a normal maintenance step.

    Should I unplug the TV during pixel refresh?+

    No, since interrupting the cycle stops it from finishing. Leave the TV plugged in and let it complete.

    How often does the TV run it?+

    Short cycles run after several hours of use, and a longer one runs after a much longer time. The maker's manual gives the details for your model.

    How can I protect an OLED from burn-in?+

    Vary the content, avoid leaving static images on for hours and use the TV's built-in care features.

    Are the lines on the screen a defect?+

    LG says you may see vertical lines during the refresh and that this is not a malfunction.

    How do I run it myself?+

    LG gives the path Settings, Picture, OLED Panel Setting, Pixel Refresher.

    What does the pixel refresh do?+

    It evens out wear on the pixels by measuring and compensating in standby. It usually runs after long use and lasts a few minutes to an hour.
