I have a fairly new (december 2008) Samsung Series 6 650 (52" LCD) -connected to a sony dav-hdx275 surround sound system (Optical connection) -connected to a 5 disk sony dvd player (came with the surround system) (Hdmi) -connected to a sony ps3 (hdmi) -connected to a verizon cable box (hdmi) I have looked on various samsung forums for an answer to my possibly simple fix I need to do. Here is what happens Whenever I play my ps3 my tv screen randomly blinks off for about 3-5 seconds while it restarts. When this occurs my speakers make a turning off crackle type sound.. but then it continues to work.. doesnt happen at linear intervals, it happens sporadically. The tv does not do this when I watch tv or play music on the surround sound, only when the ps3 is connected. My first thought was that it could have been the ps3 over heating (the shelf it was being held in was kindve cramped) so i moved it out. Still, the same problem. I am guessing it is the TV, but I have absolutely no clue. If anyone needs pictures please let me know Random note: I called samsung and told them the problem and they said that I probably shouldnt be using video games on it, but the user manual says its okay and so does a few of the FAQs on their website.
