I have just found a PDF of the Series 5 plasmas and saw an interesting comment about the 'Screen Savers': All 3 can be started up in manual mode, or they can be set to automatically start/stop at preset times in timer mode or for preset periods in interval mode. What are the 'timer' and 'interval' modes. Obviously 'manual' is when you go into the menu and select 'on' The same document goes on to talk about the 'Professional Menu' where you can set: On/Off Timer: Automatically turns the power on or off at preset times But how do you program WHICH screen saver operate at WHAT time. Even if this is the 'timer' mode they are talking about, what about 'interval' mode. I am not sure if its even worth bothering with, but if there was a way to have the 'white bar' running every night for 10-20mins, I would be tempted.
