To reduce the "image retention" Panel adjustment function is newly introduced for OLED models TX-65CZ950 series.
When "image retention" is not reduced by this function it seems that the "image retention" is permanent due to deterioration of OLED cell.
During the Panel adjustment period please avoid touching or exerting any pressure on the screen e.g. wiping the screen, etc.
If the Panel adjustment has been completed LED lights Red or Orange (standby mode).
The Panel adjustment function starts running automatically after switching off to standby if the TV has been in operation for at least 3 hours since the last panel adjustment.
If the Panel adjustment has been interrupted before completion it will start again after the next switching off to the standby mode.
