I have a 40PFL7705DV/F7, software out of the box is PHL_0DA_713_0

I just bought it today. All the TV stations are coming in as 4:3 with side black bars. We have tried changing the setting to Auto or Wide Screen but it does not make the screen wide enough to make it full screen.

If we change it to 4:3 it gets very small width. The Auto & Wide Screen are a little wider but not much, and are the same. So the black bars remain no matter what I watch.

I thought I would see 40" by buying a 40" TV. This one looks like a 32" now, but maybe a little taller.

Can anyone help me set this so it will fill the entire screen? (stretch it out?)

Thanks, Carol
