I have an old SD Rogers Scientific Atlanta cable box that I got from Rogers back in 2007. Ideally I'd like to leave the cable box turned on at all times because I use a TiVo with it and the box needs to be turned on in order for my scheduled programs to record. I've found though that it seems every 3 days or so of leaving the box turned on, it automatically turns itself off. Is this some automatic energy saving feature? Is there a way that I can just permanently leave the box powered on?
