Care for an LG OLED without overusing Pixel Cleaning
Separate temporary image retention from a persistent panel problem, preserve automatic compensation cycles, and use manual Pixel Cleaning only when the documented symptoms justify it.
Direct answer
The shortest reliable path.
Let the TV complete its automatic panel-care cycles by leaving it connected to power after normal viewing. Reduce repeated static elements and first watch varied full-screen content when faint retention appears. Use manual Pixel Cleaning for persistent lines, spots, or retained images—not as routine maintenance—and contact LG if the symptom remains after the documented cycle.

Procedure
Do this in order.
- 01
Rule out the source and overlay
Change to a built-in app, open the TV settings overlay, and test a neutral moving image. Restart the source device if the mark appears in only one input or app.
- 02
Return protective controls to normal
Enable the model’s documented screen-protection controls and avoid maximum brightness for long static sessions. Do not repeatedly disable logo or screen-move protections.
- 03
Allow automatic panel care to finish
Turn the TV off normally with the remote and leave AC power connected. Do not cut power at a smart plug or switched outlet immediately after viewing.
- 04
Use varied content before a manual cycle
Watch normal, varied, full-screen video and recheck the same neutral test image later. Compare with the original photograph rather than memory.
- 05
Run Pixel Cleaning once when justified
If lines, spots, or a retained pattern remain, follow the exact Pixel Cleaning path for the model and let the process finish without disconnecting power.
Diagnostic matrix
Read the result, not the guess.
| What you see | Check next | What it means |
|---|---|---|
| Mark appears on one HDMI source only | Open a built-in app and the TV settings menu over the same area. | The source or its video path is more likely than the OLED panel. |
| Faint shape fades with varied content | Compare the panel with the original neutral-image photograph. | The symptom behaved like temporary image retention. |
| Automatic care never seems to run | Confirm the TV remains connected to power after standby. | A switched outlet or smart plug may be interrupting post-viewing care. |
| Line or spot remains after one completed manual cycle | Document the result and contact LG with the exact model and images. | Repeated owner-run cycles are less useful than model-specific service assessment. |
Stop conditions
Know when not to keep changing things.
- Do not repeatedly run manual Pixel Cleaning as preventive maintenance.
- Do not disconnect power while a documented panel-care cycle is running.
- Stop and contact LG when the panel shows physical damage, abnormal heat, smell, or a persistent defect after the documented procedure.
