I have a panasonic viera tv tc-p50s30 and just bought a panasonic blu ray player dmp-bdt320p and am trying to hook the two up. i cannot get hdmi 1 to work. hdmi 2 works fine which is where the cable box is hooked into. hdmi 3 works fine but we would prefer not to use this because all of our wires are buried behind the wall except for hdmi 3 (don't ask). we cannot get a cable signal working in hdmi 1 either. so in other words, hdmi 1 does not work period. looking for help.
