My Sagem Freeview box keeps losing its signal?
 
                This box has served me well for a few years now, but just recently, it's started to lose its signal and request a channel rescan, showing no picture until the rescan is started.  Switching off the automatic update prevents this, but means that periodically, it loses its signal for a few seconds , then before finding it again, flashes up the "Sagem" boot-up page.
Any ideas?
