We are using a Philips TV for monitoring services, and it needs to be on 24/7. Problem is, every four hours when there has been no activity with the remote control, a message is displayed that says: "If no any operation,TV would shut down in 1 minute". At that point, the user will have to press pretty much any key, which will sort of reset the "cycle". This is quite inconvenient, and after thorough investigation throughout its menus, I could not find any option to disable it. Please advise.
