My daughter recently got a new Tivo and shipped me her old series 3 HD (252160), which had lifetime service. I got a cable card from Comcast and set up a Tivo account for myself, transferring the service. It was great! I set up the box for my channels, scheduled season passes, and all worked well....for 1.5 days. Then suddenly all the lights started blinking and the Tivo shut off. Then the green light would come on, the powering up screen would come on, then after a minute or so it would shut off and start over. Occasionally it would get to the "just a few more minutes" screen. Once it even worked for about 15 minutes. I opened the Tivo and found that the fan blade was laying on top of the power supply....presume it had come loose during shipping. I replaced it, and the fan worked, but that didn't solve my problem. I wondered if it had gotten too hot and burned something out. Sometimes the green light would blink while it was cycling as described above, so I tried the hair dryer trick with no success. I don't know where to go from here. I use a chromebook for daily surfing and shopping. My laptop computer is old and slow. Also, I don't feel comfortable doing electronic tests myself. I have called two "electronic repair" shops in nearby South Bend, IN and both tell me they do not work on Tivos. I am a older widow, and can't afford a repair at WK, especially since I don't know what costs I would be getting into...their prices seem outrageous. Are there not any other places that work on Tivo's? (I sure can't find any!) I would be okay with taking it a hundred miles or so if I could find a repair person. Or should I buy a used Tivo and try swapping out the hard drive and/or the power supply. One capacitor looks very, very slightly raised at the top...I think. Should I get it replaced before doing anything else? And by whom? These "electronic" shops? Any advice would be appreciated.
