So the House without the HDMI cable has composite or component cables?
BLUE/GREEN/RED or the standard red/yellow/white?
I think you will have to change settings on your PS3 for you to be able to see the screen.
It's like when you have a HD tv and a non HD tv. If you are at the HD tv and set the PS3 to 720i and then take it over to the non HD tv, you won't be able to see the picture unless you change the settings because it is currently set at an HD video quality.
