    Here's another test scenario to try.

    Put the Tivo into stand by when you are done watching.
    Live TV will (should) bring it out of stand by when you are ready to watch again.

    If doing that keeps it from rebooting, that's all little less hassle for you.

    Fingers crossed, but I believe the kickstart 52 has fixed it. Hasn't reboot yet in 4 hours since I performed it. So it looks like it was some sort of corruption. Which makes sense I guess. It explains why it would only do it while not viewing. Trying to do whatever it does while the tv is off and kept screwing itself up.

    Well, kickstart 52 turned out not to work, either. Putting it in standby doesn't prevent it from rebooting either. So I guess I'll just power cycle it every time I want to watch tv. No big deal, it only gets watched for a couple hours a few times a week anyway. What sucks though is I cannot schedule it to record anything.

    But I will not be giving TiVo any more money to fix their 3 1/2 month old product.

    So maybe you might reread what the design engineer noted long ago?

    I don't have a problem with opening it up. Are they any specific checks i can do to determine if its a power supply problem? I have an electronics background and am comfortable checking voltages.

    Also, as far as the hard drive.....it was mentioned to run mfr diagnostics on it. Any instructions on what to do? Thanks

    If the problem started before the 90 days was up, you need to find someone who knows just as much about your situation as you do but is capable of remaining calm and diplomatic, but firm, to discuss this directly with TiVo.

    There is much less chance of an S4 having power supply problems than an S2 or S3, especially so early in it's life, and the failed update scenario sounds the most plausible, because they tend to do the rebooting in the middle of the night when there's nothing scheduled to record and there hasn't been any remote control activity for some time.

    Manufacturer diagnostics are typically designed to operate on a PC. The hard drive could be temporarily connected as a slave drive (or maybe a master) on a PC. Then boot the system from manufacturer diagnostics typically on a CD-Rom or memory stick. Diagnostics either obtained from the manufacturer web site. Or from Bootdisk.com.

    Tivo power supplies are typically simple. A separate board often with a cable to the electronics board. Simple to identify each DC voltage. Then measure each with the meter. Of course, 5 and 12 volts will also appear on a cable that powers the drive. Post numbers for each voltage to three digits.

    5.1v reading is 5.09

    12v reading is 12.29

    OK, so how do you solve the failed update? I've performed all the kick starts pertaining to any software. Clear and reset the whole system and start over?

    I would only do that as a last resort, especially if you want to try and save the recordings.

    I would first test the drive with the manufacture's diagnostic tool, on a PC.

    Download the Ultimate Boot CD iso and burn it to a CD.
    http://www.ultimatebootcd.com/download.html

    On your PC, disconnect any hard drives you don't want to test, just to be safe. It's not really necessary because you can select which drive you want to test, but it's easy insurance if something goes wrong.

    Hook the Tivo drive into the computer. A direct SATA connection will be faster, but a USB adapter will also work.

    Boot the computer with the Ultimate Boot CD you previously burned (you may have to go into the computer's BIOS to enable this) and navigate through the menus to find the WD data lifeguard utility and run the long test.

    This should give you a definitive answer if the hard drive is going bad.

    That's within allowable variance, but just for grins, disconnect the hard drive and measure again to see if the regulator circuitry still keeps them about in the same place.

    OK, the drive is a Seagate. I'm assuming I need to use seagates seatools instead? And just to be sure, there is no danger of any data corruption using these tools?

    Well the drive passed seagates seatools long test.

    Voltages without hard drive are 5.09 and 12.33

    So what now? Sounds like some kind of software corruption or something else besides hdd and power supply. I've done the kickstart 52 several times. What's left? Reset and do the setup again?

    Did you take those voltage reading with the TV in a good connection and a failed connection state? IOW do not disconnect any wires or change any conditions (including the state of the TV) to make measurement during the failing setup.

    One final test of that drive. Use a hairdryer on high to heat the disk drive's computer (PC) board. If a drive is OK, then it will pass all Seagate read tests even at that higher (and normal) temperature.

    Heat is fabulous tool for locating intermittent defects. If the drive fails at that higher temperature, then the drive is defective. If not, only remaining suspects are the mainboard and connections to it.

    Don't recall details on each connection. Is it coax cable? What specifically connects to what?

    You might also perform the heat test on the mainboard. If heat cause failure to occur more frequently, then you know exactly where the intermittent defect is. Not a most likely suspect. But an easy test.

    So the stock hard drive that came with that Premiere is a Seagate?

    500GB?

    I'm suspecting its the HDMI cable. I swapped it out before I left for work. Will see how things are when I get home.

    A major difference between a coax cable connection and an HDMI connection. HDMI means galvanic isolation routinely found on coax connections does not exist between Tivo and TV. Does that change a list of suspects?

    It's the hdmi cable. I changed it to a different one and its not rebooted all day. I thought I had ruled it out earlier when I was testing with one connection at a time but I must have missed it. I put the bad one back on and sure enough within minutes it had rebooted. I'm assuming a bad pin or a short or something in the cable was causing the tivo to reboot while the tv is off.
