  • PS? 2 bad disks? Motherboard?

    I have a Tivo HD w/ lifetime subscription.

    I bought it used a couple of years ago... but I know the person that had it and they really never even set the darn thing up. It was for all practical purposes new.

    I immediately updated it to a 1GB drive and stored the original away in a safe place.

    Yesterday the drive seemed to start acting up. I got 2-3 reboots... then this morning it was a cyclic reboot. I forced a green screen on it... and it went cyclic before the green screen should have finished.

    I RMA'ed the drive (still under warranty) and fetched the original. I put the original in and it worked fine. I forced a few connections to tivo and forced a reboot (it said it had updates pending a reboot) to get it going and all seemed right with the world.

    6 hours later, it's cyclic. Sometimes it gives "welcome, powering up" and sometimes it falls back to a fast blinking green LED -- no video out. Reseting the power seems to get it back to Welcome.

    Ideas?

    Check the power supply for burst capacitors:

      All capacitors look (to my untrained eye) flat-topped and non-bulging.

      I unplugged the box last night about 8pm.... plugged it in right before bed. It booted fine and right now it's still up, though I am not so confident it will stay up.

        I'd still guess it's a bad power supply, actually. We do see most bad ones showing some bad caps, but a definitely minority are bad with no visible evidence.

          holding my breath after 12 hours uptime... but will probably try ordering one when it dies.

            Try recording two channels at once - sometimes that'll draw enough extra current to put it over the edge of it's output capacity.

              I've had multiple dual recordings with no issues yet. I won't trust it until it's been up a month or so.

                OK - tell us what you find.
