    Thanks for the software image. Alas, I still can't get it to go past the "Welcome, Powering Up." screen. Looks like I will be investing in a new power supply.

    On that model there's a cap or two tucked under the heat sink overhang (the hardest ones to get at, of course) that are probably the problem if the power supply is the problem.

    Eyeball them before you go laying out $100.

    I visually inspected all of the caps and none of them appear to be ruptured or buldging. Is there a way to test each cap?

    Yes, but...

    First get a voltmeter and check the yellow wire for +12V DC and the red wire for +5V DC, and see how close to those values you get.

    The black wires are ground, as is the metal chassis.

    You can test by unplugging the 4 pin Molex power connector from the IDE/PATA hard drive (or IDE/SATA adapter) and sticking the meter probes into the holes, just don't let the probes' metal parts touch each other while doing that.

    And you can plug the plug back onto the drive and "backprobe" to see what readings you get with the drive drawing current as well.

    You can have a bad cap that doesn't have visual signs of having gone, or being in the process of going, bad.

    Come back with the +12 and +5 line readings you get with and without the drive attached (in addition to the motherboard always attached) and we'll go from there.

    I've already checked the voltages on the molex connector. Without the drive plugged in they read +12.2 and +5.1. With the drive plugged in, the voltages drop to +12.1 and +5.0. These voltages seem to be within tolerance.

    Congratulations, you have a good power supply and will have to look elsewhere to figure out what's causing your problem.

    The only other part that it could be would be the motherboard. I'm assuming that there is no way to test it.

    Are you absolutely sure the drive is good?

    Are you absolutely sure the 40 connector IDE ribbon cable from the motherboard to the drive is good?

    Drive passes all S.M.A.R.T test and manufacturers long tests. I've even tried a brand new factory fresh drive amd a brand new ribbon cable.

    Okay, if it's desperate measure Hail Mary play time, replace the coin cell battery with a nice fresh one straight from the store, power the drive from a PC power supply, and then plug in the TiVo, but first run mfsinfo on the drive with either the MFS Live cd or WinMFS.

    What drive are you using? Western digital may need WDidle3.

    Because of the need for a WD and not the "bigger by a few more LBA" Maxtor image, I assumed it was the original 80GB drive, i.e., not a Caviar Green with Intellipark, which has got to be the better part of a decade old and I'm not sure that age might not be a factor in spite of it passing all tests.

    I've already replaced the clock battery on the motherboard. I've tried powering the hard drive with an A/C adapter that goes with my USB-IDE/SATA hard drive adapter. Everything looks good in mfsinfo.

    I was using the original 80GB originally. When that didn't work, I purchased a WD5000AVDS and a SATA to IDE adapter from WeaKnees. I loaded the software image that Unitron provided to me on the 500GB drive and verified that it came from WD with Intellipark disabled. And if I'm not mistaken Intellipark only affects soft boots, not hard boots.

    Sometimes it also affects hard boots.

    The IDE/SATA adapter could also factor in the difficulty.

    Is that board lifetimed?

    If so, do you have another 540 board?

    The SATA adapter isn't in the loop with the original drive.

    The board is lifetimed and it's a 240 board. It's the only 240 that I have.

    Got you and the other guy confused together.

    The lifetime sub is tied to the TiVo Service Number.

    The TSN is contained in the crypto chip on the first Series 3, the TCD648250, and all of the Series 2 and Series 1 models.*

    The crypto chip in your 240 can be moved to another 240 motherboard (even if the last three characters, that indicate hard drive size, are not the same), but it requires someone with the right equipment and experience in soldering and unsoldering Surface Mount Devices, or SMDs.

    I had to do it with a dual tuner S2 and it was no fun at all, and even having practiced in advance on junk boards I nearly screwed it up.

    But it can be done if that's the only way to save the subscription.


    *Unfortunately for me, they moved the TSN into another "bigger, more complicated, impossible for me to even think about changing out" chip on the next Series 3, the HD, and all models since.

    Anyone still have a TCD540040 image stored someplace?
    I would greatly be in your debt if you PM me the info.

    Thanks
