I think my Premiere (746320, upgraded to a 2TB HD, with lifetime) may have bit the bullet, but am not quite sure what is wrong with it. The TiVo is completely unresponsive; there are no lights on the front of the unit. Doing a hard reboot of the TiVo yields the same result, it doesn't even get to the first gray screen. To give a little background, this particular TiVo had been having occasional (a few times a year) problems where I would hit the TiVo button to take it out of standby, and I would get no audio or video signal. All of the lights would light up on the front like normal, and you could see the flashing amber light on the unit in response to the remote, but no audio or video. Originally I would have to reboot the TiVo to get it out of this state. More recently I bought an iPad and I discovered that I could still connect to the TiVo through the iPad and if I browsed to a show on the iPad and tried to play it, then the TiVo would get unstuck and start playing the show and everything would be normal again. I dont know if that is a precursor to the unit dying or not, but the TiVo did exhibit this behavior 1 day before it died completely. However, we also had a thunderstorm in the overnight hours on Wednesday night and there was one lightning strike which appeared to have been VERY close by. My TiVo is on an APC battery backup, but for power only, not the ethernet connection, nor the coax coming in from the antenna in the attic (I am OTA only). The rest of my AV setup in that room seems to be okay, although I will admit I have not tested every other component yet. I opened up the TiVo to check the power supply and I didnt see any apparent bulging capacitors. I have a Series2 that I have replaced the power supply on and I have seen bulging capacitors in desktop computers before, and I have seen other pictures on how subtle the differences can be, so I think I know what I am looking for there (but I will readily admit I am not infallible). Is it possible the power supply can go bad without any apparent bad capacitors? I also put the TiVo on a Kill-a-watt and noted that the TiVo is still powering the fan and the HD is still spinning up (I know a PS can be bad with both of those still being powered), and the TiVo was drawing 0.33 amps and between 19.6 and 19.8 watts. I dont know if that means anything, but I did grab that data. If I did get a surge through the coax, then would that point to the motherboard being fried & possibly beyond repair? It seems to me the best course of action would be to try a new PS first, and then if that doesnt work, to get it diagnosed by Weaknees? Any other ideas? Sorry for the long post!
