So last week my series 2 DT when I turned the TV on was video frozen. What I mean by that is there was a picture of a show and not moving. None of the remote buttons did anything to affect the condition. So I unplugged and rebooted the unit. It started working again after the reboot, but did show some signs of temporary freezing w/some pixelation. I only watched TV for a short time, maybe an hour, and it froze and pixelated a few times. Annoying yes, but it otherwise worked. Shut the TV off to sleep and when I woke in the morning turned on the TV to watch the morning news it was frozen again. I rebooted it and it worked again before I left for work. After work it was frozen again. Another reboot and it was frozen within the hour. I assumed the hard drive was failing. It has the original drive and an upgrade drive. I took the cover off and it was caked with dirt especially on the upgrade drive aux fan so I took it to work and used the compressed air to blow it out clean. I grabbed my series 2 single tuner and hooked it up (it hasn't been hooked up since Nov last year and worked when disconnected) It wouldn't even fire up. I took the cover off of it too and it had some dirt build up also and I blew it out clean too. I think the power supply is bad because the green light didn't even come on. It still wouldn't fire up. After doing some research found out about "capacitor plague". Now here's the odd thing, The DT HAD "capacitor plague" but acted like a dying hard drive, but the ST didn't have it but acted like a bad power supply! I think I'm going to replace the power supply in both to start with and see if that cures the problems with them. I was going to swap power supplies but found out even though they look similar they aren't the same and therefore not swappable. I found power supplies for both on ebay considerably cheaper than weaknees has them for. If it fixes them both great! If not then it's a good thing I don't have lifetime subs on them. I then went back farther and grabbed my series 1 svr2000 and plugged it in.......IT still works! with no phone line at my house, I put a Turbonet card in it a few years back, and after receiving a 50' ethernet cable in the mail today, plugged it into my network, activated the box (after successfully making a test call) I now have up to date guide data! So in the span of a week, I went from 4 working TiVo's to 2! Good thing I only have 2 TV's setup. I do have another working TV but don't have it set up right now. I down graded since my ex-fiance' and her daughter moved out. I do have another svr2000 and I think a Turbonet card might fix it too because I burned out the modem in 03 trying to upgrade to an Airnet card. I'm just not sure if it did any other damage too. It did still work as a manual recorder though. I also tried putting the 2 large hard drives in the svr2000 from the first svr2000 that I upgraded but when it powered up I got GSOD loop, so I had to put the original drive back in. I'm going to redo the large drives with a fresh image and see if that gets them going again. I'm just happy to have 2 TV's and 2 TiVo's again.
