Advertisements My lifetime Sony TiVo S1 is having telephone problems. I had no dial tone on the line I use for my fax and the S1. I traced the problem to the S1. Here are the symptoms: 1) TiVo in normal operating mode, the telephone line is off hook and no dial tone (due to being off-hook for too long a period). 2) TiVo telephone line disconnected from wall jack, the telephone line goes on hook and I am able to get a dial tone from any other telephone on that line. 3) TiVo power off and its telephone line is connected to the wall jack - telephone line normal. 4) Power up TiVo - telephone line goes off hook. I assume it is a modem problem and replacements are available from the usual advertisers on this forum. Is my assumption correct? Do you recommend a replacement modem or a network interface board? I want to minimize the cost since I will be purchasing a new HD model and use this one to assure MSD. Thanks.
