Re: Sony KDL-46Z4100 another TCON problem?

My tv has the stripes but when I first turn it on the picture is fine. Then the picture freezes for about 20 seconds and the color inverts then changes to stripes. The picture returns if I shut it off and back on again or sometimes it will come back after a few minutes without me having to shut it down. Any ideas of what might be going on with it? Thanks for any assistance
