Samsung UE48H6350AK slideshow start.

[Bulvasaur]

Hi!
Can enyone help me to solve one little problem?
I have samsung UE48H6350AK and I want from it to start at certain time and run a jpg slideshow from USB-flash. Such function is described in manual and must work well. But every time the TV-set turns on it asks me to set up channels. But when I turned on the TV-set at a very first time I "told" him not to be used with antenna but only as a screen. How can I make this function work. It is not available to me to connect an antenna to set up channels. Is there a way through the service menu to set up a default source as a USB? Or may be SamyGo can help me somehow?
I will be greatful for any advice.
