I have a Panasonic BD-35 connected to a Sony DA2400ES receiver via hdmi into the BD hdmi port. Overnight the signal has failed. If I swap the cable over to the DVD hdmi port on the Sony everything works fine. None of the settings of either box have been changed. It may be a silly question, but does this mean that the BD port is broken? If so should the picture via the DVD port be of a lesser quality? I don't have a separate DVD connected. I bought the Sony from richer Sounds in Feb-09; will they give me a new one or mess around trying to fix this one?
