You can enter the hidden menu in your JVC Smart TV by pressing MENU button in your remote and 1147. In that menu there are some characteristics you can change according to your requirement. But there is a mode called AGING MODE and dont press it. This video shows that if accidentally press the AGING MODE (Screen colour changing in to blue green red white and black)and unable to exit press power/ standby button for 5 seconds. Your JVC Smart TV would return to switchoff mode and when switching on it would exit AGING MODE and return to normal mode. Hope this would help you. Thank you
