If Picture reset mode is On and you disconnect and reconnect the power cord (mains lead) and then turn on the TV, the power goes into standby for approximately 10 minutes to perform panel calibration.
After panel calibration is complete, the power turns on again and the TV screen is displayed.
This symptom can be avoided by setting Picture reset mode to Off.
- Press the HOME button on the remote control.
- Select Settings.
- Select Retail mode settings in the System preferences category.
- Select Picture reset mode.
- Select Off.
