I have a TiVo branded S2 SA that powers up and finishes with the message to press Live TV or the TiVo button. It goes into standby but I can't bring it out. The remote appears to be working, but it looks like the DVR doesn't response to it. I even reset the DVR 1 and 2 switches on the remote and did a global reset on the remote but nothing seems to work. Any suggestions?
