I have a sony KP51WS520 rear projection TV, and up until a few days ago it was working fine, but now it is doing some funky stuff. I have a Direct TV HD box, that appears to be working correctly. I have it hooked up to the TV with an HDMI cable. All channels look crisp and clear and there is a distinct difference between the HD channels and the others. I also have a Sony upconverting DVD player, and have a HDMI splitter box so I can switch back and forth betweeen TV and DVD. When I switch to the DVD player, the screen know just flashes once every 8 seconds or so. I thought it might be the splitter box so I seperated that, tried different cables and replaced the dvd player (through the warranty). Like I said everything was working fine till a few days ago. Any help or suggestions would be appreciated. Please forgive if I posted in the wrong place. Thanks, Country7922
