Make sense- a while back my Wii was showing some weird static lines on the screen in 480p mode (480i is ok) - turned out it was the made in china 220V ciplak power brick giving problem, switch back to my original 110V brick (have to use stepdown which was the reason I got the ciplak 220v one) and everything ok.

Now where can I loan a Jasper compatible power brick? the ones I have are the old pre-Jaspers .......
