Last week, there was a power failure on my block. After the power came back on, my series 2 was fine but my older Tivo series 1, Philips model #HDR32104, isn't working at all. I've tried disconnecting the power for up to a minute, but still nothing. The green light on the front of the unit comes back on, but I get no response from the TiVo at all. Any suggestions? Thanks!
