I've just tried to connect my Sky HD and Sony DVD player (HDMI) via my Onkyo 604 to my LG 42PY10X plasma (HDMI to DVI cable) when I do the picture turns a purple colour. I've tried this setup to a different LG and the picture is fine. HD box/DVD player into LG are also fine just seems to be an issue between amp and plasma. I've e-mailed LG in the mean time has anybody got any ideas? I know the plasma is old but didn't really want to upgrade till the end of the year.
