C701 is definitely a 2200uf 25V as that's what I just pulled from my original power supply. Cap replaced now I have to wait till I get home to power it up and see what happens. Crossing my fingers... UPDATE: Sadly, no change. Still have the original error. Looks like I have to go to plan B and replace the box. The unfortunate issue is that this is my box w/ the lifetime. 'Fortunately', Tivo is offering to discount a refurb unit and transfer my lifetime to that box. It's much more than I 'think' I should be paying for a customer that's been w/ them since the late 90's but at least that box will have a warranty for a period of time and I'll have some newer, Premiere-level features. Thanks to Unitron and pmiranda for the guidance and suggestions. It was worth giving a shot and would've been nice if it had worked.
