I had my PS3 setup on my sons television upstairs with just the normal scart lead, we got a new panasonic plasma and set the PS3 up via a HMDI cable which is really good, i went to set up the PS3 again upstairs via scart and cannot get any picture or sound, i've even tried on my daughters small lcd via HDMI and still nothing, the PS3 only works on the new Panasonic in the living room, can any one help please, as my son is giving me grief big time!
