My series 3 is lit up in front and nothing is happening, so I suspect it's a power supply. I have to go out into the black widow den (aka the shed) and poke around until I find a T10 or get bitten on the hand, whichever comes first. But in the meanwhile I thought I would set the TV to get the cable signal directly so my wife could watch live TV. Then I realized I don't have a cable box--I have 2 cable cards in a dead machine. So I'm right in thinking that I can't watch TV until I get TiVo fixed, right?
