Unknown model of panasonic tv problem with picture

Question

Hi i have been having a problem with the tv .... it has been flickering quite fast but only slightly, then all of a sudden after turning the tv off (trying to sort out the flickering) then back on again there was no picture until about ten seconds later. The picture was a dark red and sort of smudged with faint horizontal lines about an inch apart. Any solutions? My partner said it should be thrown away ....is she right?
