Panasonic AG-455 won't give me a picture?

I have an issue with my Panasonic AG-455b, The only way I can use it is through a main power socket since I cannot find a charger for the two batteries I own. My main issue recently is using the camera itself: when I turn the camera on the viewfinder only displays 0000 in the top of the image and x100 in the top right flashing white on and off rapidly, there is no image in the viewfinder only a black screen and the flashing of the icons, this is the first time this has happened.
