Have used a Samsung LCD TV and Hard disk/DVD recorder OK with a HMDI cable.
Have now updated to Panasonic TV and Blu Ray.
TV fine, Blue Mechanically working (according to Blu Ray display, but no apparent connectivity via my existing HDMI cable to either new or old TV.
Old Hard Drive does connect to new TV , via old cable,

fine.
Are there differing HDMI standards or is this likely to be a Bluray box issue?
