Off is a maintenance state in this manual
The OLED55B3PSA manual describes automatic pixel cleaning after the TV is turned off, based on accumulated use. It says the feature operates with mains power connected. Cutting wall power immediately is therefore a different condition from normal switch-off.
Keep the scope exact: this is the B3 model manual’s procedure. Do not invent the same schedule or timing for every OLED television.
Let the TV follow its documented process
Use the normal power control at the end of viewing and follow any manufacturer prompt. The manual also describes possible visible lines during cleaning, which should be read in context before diagnosing a playback fault.
Do not create a repeated manual-cleaning routine merely because the menu contains a Pixel Cleaning action. The manufacturer’s automatic behavior and condition-specific advice should guide its use.
Keep persistent problems separate
If an image remains visible across sources after the documented care, record the model, symptom and care state for LG support. A maintenance article cannot certify that a panel has recovered or predict its remaining life.
This distinction explains why a dark screen can still require power. It makes no measured energy, burn-in prevention or restoration claim.
Questions answered
Can normal off and wall-power removal be treated as identical?
No. The model manual requires mains power for the described automatic process.
Does this guide promise image-retention removal?
No. Persistent panel symptoms need model-specific support assessment.
