I have a Series 3 with the SPWR-00008-000 RevA3 power supply which I have removed and don't see any obviously blown or leaking caps. Was thinking of buying a working Series 3 on ebay and swapping the power supply rather than paying weaknees $99. I'm not comfortable enough with the solder skills to fix it myself but if I could diagnose the caps as the issue, I could probably order the ESR ones others have linked to and find someone to solder it in. The unit has lifetime service and I had actually sold it on ebay for $375 but it was returned to me with the power supply problem between when I shipped it and it was returned. I don't *think* the buyer pulled a quick swap on me and I don't need the TiVo anymore since I use DirecTV but would like to get my value out of it so am looking for suggestions on how to fix/diagnose.
