Have enjoyed the Samsung plasma TV connected via HDMI to a Panasonic DMP-BD35 blu ray player for more than eight months. Suddenly the connection no longer works; the TV no longer recognizes the HDMI-connected blu ray player. Changing HDMI cables results in successful recognition via HDMI 4 ONLY, and only video but no sound is observed. Composite cable connection works fine. Blu ray connection to another tv via HDMI works with only one of three cables. Seems like a combination of HDMI cable failures as well as the HDMI input board in the TV. Thoughts? Thanx!
