O.K. This is a wierd one! Even the excellent Sony helpline hadn't got an answer-

I have a Sky+ box connected to an input HDMI of the TV (tried all of them). The picture is fine but there is no sound.

I've tried different cables. All are working.

I've tried connecting to another TV. The sound is coming through fine.

Every unit in the system works with other TVs (leaving me to belive that there is a strange anomally with the KD-55s HDMI inputs)

I've been through all the menus on the KD-55 TV and sound is selected correctly. Sony tried this too and all is correct as far as they're concerned.

Now here's the wierd thing-

If I connect the scart output of the Sky box to an older model Sony HD/DVD recorder and then take the HDMI output from that to the KD-55 TV - The sound comes through! The problem with this is that the picture is then a lower grade due to the scart in the system.

Can anyone help?.. Please?.. It seems that Sony have not come across this before and cannot help (yet).
