    Hi,

    I'm having audio problems whit my TiVo HD. I previously had problems with the picture freezing and I replaced all of the capacitors on the PS with the help of the tutorial here at TC.

    Now I have no audio sometimes at half of my channels and I know that it's not my source because I have OTA and I put the input on my TV and I did have audio.

    Any Thoughts ?

    Thanks,

    Try switching audio "Dolby to PCM."

    Are you using HDMI?

    Thanks, I will do that. It was on Dolby, only.


    Yes HDMI to the TV.

    Try composite/component as the HDMI ports can go bad in TiVo HDs.

    It did it again but also the video froze a bit during America's got talent.

    I opened the AVR receiver and I had no audio from the optical output and the RCA outputs also.

    Bummer!

    Did you ever remove the drive, connect it to a PC, and run the drive's manufacturer's diagnostic software's most in-depth test?

    This. As soon as the problem went beyond audio-only, this would be my advice as well. TiVos are not capable of dealing with bad sectors, other than trying to work around them. Mfg diags can find and mark the sectors on the read test, sometimes recovering the sector. The "destructive" write tests will either reclaim the sector (in the case of a false pending result), or reallocate a "spare" sector in it's place.

    There is some disagreement on bad sectors, around here. Some consider any reallocated sectors a sign of imminent drive failure. Others see it as "to be expected", since no platter is 100% defect-free.

    The TiVo has the "Kickstart 54" diagnostics built-in, to perform limited tests on the drive. They are better than nothing, if you don't have access to a PC. They can do more than the TiVo can, when it's in the usual state of 24/7 processing of AV streams, and has to keep the data moving at all times.

    Sometimes it's worth running the TiVo tests, since they can detect problems, and might give an instant "FAIL 7" result (which means it's time to run PC-based tests, or just replace the drive (which should be PC tested before installation).

    Any chance the TiVo is using the secondary audio program (SAP)? Some channels may not provide audio on the SAP.

    I don't think so because I lost the sound during a 2 hour show.

    I will run the Kickstart 54 program tonight and I will report.


    Thanks Guys !

    I ran the test and it's ok. If you check my picture, the timer went to 45 minutes, I don't know if that is bad ???

    I will pass the overnight automated test.

    That it took less time than estimated, completed, and passed, is a good sign.

    Find your way into the SMART test for the individual first drive, where you can select individual tests, and post a screenshot of the smart attribute values screen.

    You ran the essentially "run all tests on every drive detected option", which was step one. Now you want to single out the drive and view SMART details. There will be a bunch of values around 100 & 200 on that screen, and it doesn't require any more tests to view them.

    Keep in mind that a PC and the mfg tools for the drive could still tell you more about the state of the drive. I'd be more comfortable with leaving the drive in, once I see those values (if they are good values). The values have to be pretty bad to make a fail result using TiVo diags.

    The universal advice on a unit that age, with no warranty to void, is to test with a PC (if you want to be 100% sure of what's what). If that's the stock drive, it should be wearing-down by now, and it has served you well.

    Lets see that other screen...

    After that, there's KS 57 & 58, which repair corruption of data not related to drive issues. But, be aware, sometimes running either of those two can spontaneously cause corruption. KS 52 does a software reinstall to the alternate partition, which does a disk scan that is least likely to put you into a boot-looping GSOD condition. Don't forget to fill in the blanks on the drive that's in there, and how long it's been operating for.

    I ran the overnight full test and after 12 hours, it passed.

    But I noticed that I recorded TMZ for a test yesterday and I had full pixelation, it was impossible to watch the show.

    I think I will take out the drive and use my PC for the mfg tests.

    I will report on the tests Monday.

    Thanks,

    I ran Kickstart 57 this morning and I got this screen:

    I hope you're not stuck on that screen forever. That's what happened to me when I ran Kickstart 57 & 58 and why I'll probably never do it again.

    If you've still got that screen say 6 hours after if first started with no reboots during that time, go ahead and unplug the power, let it sit for 10 minutes and plug it back in.

    If it goes back to that screen you might be able to use WinMFS to rewrite the bootpage and swap boot partitions, and maybe revive it that way.


    I really don't recommend using the TiVo to test the drive.

    If it needs testing it needs to be pulled and hooked to a PC and the manufacturer's own long test run.

    This green screen of death went away after 30 minutes.

    I will take-out the drive and test it with my PC and an external drive kit.

    This post is more for all those so quick to pounce on "worst case scenarios", simply because you posted a pic of the GSOD after running KS 57 (which is what is supposed to appear on the screen when KS 57 is running).

    It was already first advised that you should test the drive with a PC. I gave you some alternatives, since you seemed reluctant to use a PC. There is also the matter of the PC testing only testing the integrity of the disk, not the integrity of the file system, data, and databases, which is what KS 57/58/52 all will do.

    I did warn you of the fact that KS 57/58 could brick the TiVo, requiring re-imaging the drive (why this happens is not known).

    I asked for the SMART values from the KS54 > Test /dev/hda/ > SMART tests > Show Status screen, before moving forward, and considering the other tests (which had somebody's panties twisted into a bundle, before you posted the process completed without issue).

    I advised that KS 52 was the safer choice (overall, for in-TiVo testing/correcting), would do the same file system integrity checks, and re-install the current software to the alternate partition. For some reason, KS 52 only bricks a TiVo if there is something wrong with the hard drive (which would mean the drive was degrading, anyway), and it was on the way to failing.

    Since TiVos of the age yours is don't get updates anymore, you stay on one partition/installation, while the alternate gets no read/write activity. By using KS52 at least once a year, you distribute the active areas of the disk, and have a form of wear-leveling, as a result/added bonus.

    Since you seem to be running on the original drive, I will warn that it may pass every test, no matter how you test it, but the read/write times of the most-used sectors will have grown to slow enough to not work in a TiVo anymore. Slow sectors read & write, maintain integrity of the data, but are too slow for the TiVo to write/read them fast enough to not cause glitches.

    To find out the sector access times, there are some tests built into KS 54 that create a graphical view of them. There are also PC tools for this. I have, and have had, many drives with too many slow sectors for TiVo use without AV problems, that will pass every test out there, SMART and beyond. Those that were under warranty got RMAs for replacement. The others are what I use for non-critical backups of my computers, or as non-critical storage for data that is not important to me.

    If you are running a stock drive, which has had ~3-5 years of 24x7 use, or more, I'd advise just getting a new drive, getting an image from the image begging thread, and skip all this time and effort on a drive that may just be too slow, but will pass all the tests you throw at it. Money aside, you'd come out ahead that way. There are ways to keep your existing drive contents, and copy them to a new drive. There's no shortage of free tools for this, or threads that explain how to do it. You can even keep your data, move to a larger drive (2TB is easy), and reap all the benefits of a new drive.

    Plug and play, pre-imaged drives, up to 2TB, can be bought from DVR_DUDE on ebay. But, you'd lose your existing content/settings. Other members here will do the same thing for less (or even for free, plus the cost of the drive and shipping).

    And then what happened?

    Perspiring minds want to know!


    Just remember that the drive can be physically fine and still have some scrambled software on it.

    The TiVo is functional with no problems since the green screen.

    I have an usb to sata interface to test the hd without opening the computer case. My case is huge and installed in a place that is not really accessible.

    I'm sure the test will be slower.

    I think I'm going to get a new HD anyways, mine is always full.

    So I can get 2TB for this TiVo hd?

    What about this one: http://www.newegg.ca/Product/Product.aspx?Item=N82E16822236603

    Which places do you recommend for HD's?

    Thanks nooneuknow and unitron for your help.
