[admin_exported]

As i have been putting in some serious hours on xbox360 due to a dose of flu i have been trying to wash the screen every night with a snow channel. However with no signal the tv switches off after a few mins. Does anyone no how to stop this as i cant find anything that does it in the menus. Rewerb are you out there?!

Dont know. But any channel will do. Put it on BBC1 for an hour or two.
