Blade 7000 loop through Problem

Can anyone help have connect a friends New blade 7000 for them . The Blade works fine but As the Panasonic TV uses Satellite they want the Blade and the TV to connect to satellite. ( but not at the Same Time) Got a problem when using the Blade Sat Aerial loopthrough the TV will not work when the Blade is on standby. The TV will only work when Blade turned on. Then the Panasonic TV can only get H or V channels opposite to the one the Blade is using. Is there a way to correct this. On the Spiderbox there was a power saving which caused this problem. Is it the same on the Blade and if so how do I turn it Off.
