    From what I've read in this thread and the "All Video Vanishes" thread (see above for link), the HDMI issue may just be a part of the larger, more generalized situation. Certain things like HDMI, heavy file transfer, moving back and forth between screens seem to be correlated with this problem, but no one thing appears to be causal. It also doesn't appear to happen to every Tivo HD. And yet sometimes people have been told to exchange their Tivo for another and they still get the same problem.

    And there are variations: you can have black screen on some channels but not all, you can have black screen on all channels but not the menu backgrounds, or you can have black screen on all channels and all menu backgrounds. I have experienced all 3 variations in just 2 weeks.

    As for me, I'm just going to keep my Case # open and keep reporting occurrences. Sooner or later, I hope that Tivo will respond with a fix.

    Tivo HD with a multistream cablecard. Once a week I loose only digital channels (full grey screen). Two independent things fix this:

    1- Having the cable company re-hit the card for authorization
    2- Rebooting the TiVo

    So, of course, Cox Cable says its the TiVo and TiVo says it's the cablecard.

    Cox says to make sure the Tivo is v9.2 as that is more stable with cablecards. It is.

    Because of the reboot, I'm thinking that the TiVo is not talking (or listening) to the cablecard until either the card is initialized through a reboot or hit and sends a new authorization to the TiVo.

    Any thoughts?

    Any updates on a resolution to this? I think I have a form of this problem, however, my S3 outputs snow instead of blackness when it gets into this mode. It then either reboots or needs to be rebooted manually.

    I do not use HDMI, but component cables. This happens to me too, once or twice a month. So it may not just be the HDMI handshake doing this. Sometimes it comes back on reboot, sometimes magically on its own.

    It's good to know I have company in my misery! I have also encountered the full-screen snow and it's happened on two different brand new S3's over the past ten days. Actually, each one of the new machines went back and forth between a black screen and one filled with snow --about every 15 or 20 seconds or so. I have read other posts here describing this same symptom.

    I got the first one as a brand new sealed in the original box replacement unit a week ago -- it replaced a six-month old machine that had audio and video freeze issues -- and the "replacement for the replacement" yesterday -- also brand new in a sealed original box. I hadn't had time to get Cox out to my house to install cards, which tells me the culprit is neither cable cards nor the TiVo, unless I got two lemons in a row!! But I had changed the video output from the defaulted 1080i fixed on both machines and wonder if that has something to do with it. Seems like an obvious version 9.2 software problem but God only knows when/if it will be fixed.

    I'm having a similar problem.
    I occasionally have to reboot my S3 after turning-on my Sony SXRD. The Tivo just locks up, all I get on screen is black, today it was dark green. This started after I got the update that includes the external storage option. Before that, for about a month since I first bought it, it worked fine. I neglected to call Tivo about the problem, because I thought it cleared up for about 2 weeks, after I turned on the Sony's I-link power "standby option". But today it did it again. I don't know what this might have to do with HDMI, but it seemed to fix the lock-up problem. Or at least I thought it did!

    Has anyone noticed that this seems to only happen after a service connection has been made, without the TV turned ON? Or am I just seeing things?

    Turned on the TV last night and had the black screen - menus would work fine, remote worked fine. Rebooted and for about a minute after the reboot, had the "Acquiring Channel Information" screen and then live TV was fine.

    I'm connected to the TV via component through my AV receiver. No mods to the HDTivo. Wirelessly connected to internet via Tivo-supplied adapter and router, but I've only ever uploaded a program to the PC once just to test it out.

    Due to the appearance of the "Acquiring..." screen, I'm inclined to believe it's a cablecard issue, perhaps some sort of timeout is happening? It's been running just fine since it was set up more than 5 weeks ago.

    That's a totally separate issue, not the same one as this thread, which affects HDMI connections only.

    My software is updated to whatever the latest version is, and I'm having the blank screen problem (albeit with no reboots whatsoever). It happens whenever I initiate an MRV transfer and try to go back to watching live television... the blank screen shows on the channels, and I evidently can't switch channels. Going back to the TiVo menu shows no background.

    Like others here, when I try to back out of the programming, I get the keep/delete/advertisement menu.

    It did not used to do this, so I have no idea what is going on.

    Not this thread. People with this thread's problem don't see anything and cannot operate the TiVo at all.

    My S3 is 11 months old, unmodified, no external HD. For nearly 10 months, I used it w/o CableCards. Since the Scientific Atlanta Cable Cards were installed in October, almost once a week I have a situation where the Tivo won't provide any video after coming out of standby. The time appears on the OLED display, the LED that acknowledges activity blinks, but no video or sound is apparent. In most cases, it seems like recording continues in the background. Also, I can see the shows from Tivo Desktop and remotely from the "Now Playing" list of my S2DT Tivo. To me, it seems like an HDMI issue, but I haven't tried to connect via component cables. (I also have optical audio out to my Pioneer stereo, but I wasn't able to hear any sound effects either.) The Tivo doesn't seem to reboot itself. It seems very stable otherwise. I only get video back after pulling the power cord and then plugging it back in.

    In one case where this happened, during the reboot I saw the usual "Almost There" and related screens, but it went back to black as soon as the boot process completed. A second reboot fixed it.

    Finally, I had one case where I could not access the "Now Playing" list from Tivo desktop nor from my S2DT.

    I have 9.2a software.

    Okay I wasn't here when the Cox Cable guy came to install the CableCard in my TiVoHD so he said something to my mom about it taking 24 hours until the "program downloaded". I'm not sure if she quite got the message right but now I'm only getting local channels. The good news is I'm getting them in HD too, however I'm not getting even the "basic" channels like Discovery and Lifetime not to mention the Premium Basic channels CNN or MSNBC or the Digital Channels like Logo and Boomerang.

    Anyone else out there in Phoenix have to wait 24 hours or had this problem? Also I'm wondering once all this IS working will I get the Music Choice channels and everthing like the old Cox Digital Cable Box had?

    Well, I had it happen again yesterday. I guess twice in 6 weeks isn't really a problem, but I just worry that it's a sign of worse problems down the road.

    Once again, the lock-up seemed to correspond to the exact time that I turned on my tv, since that matches up with the time that the TiVo seemed to stop recording (although the display fooled me into thinking that it was still chugging along for a while). Again, to me this seems to suggest an HDMI issue.

    Yet another episode yesterday. I could see the time on the OLED, and I could see the programs remotely from my S2DT, but no video or sound at all. A reboot fixed it. Still a bit troublesome as it seems like, as the code base grows in size, the Tivo software has gone from "bullet proof" to "bullet resistant"! :D

    I would reboot the TivoHD and see if all the channels come back - you seem to be experiencing an issue many of us are seeing:


    Also - Music Choice channels will still be there (in the 900's I think).

    I just had the exact same issue, with a brand new, just out of the box, unmodified TiVo HD. I have no cable cards installed yet (RCN comes tomorrow), and it is hooked up with component cables, not HDMI. :(

    And I just had the reboot again a couple nights ago. Again, not during anything I was desperate to watch, and about 2 months after the previous occurrence, so not a terrible problem. But a nuisance if it happens during something I really don't want to miss.

    After about 3 months of usage with a cable cards in my series 3, CC #1 would lose basic & digital channels but I would still get HD basic channels every 24 hrs. The original installer used a multi (in slot 1) and a single to set up my unit. I swapped cards to see if the issue followed the card or if it was the slot. When I did this, the activation on one of the cards was lost which forced a truck roll.
    Yesterday the tech came out and fought this for 2 hours. As it turns out, in my area Cox San Diego is upgrading the network, which is naturally increasing the power. With this additional power plus a COX amp that was previously installed, the tech was getting power levels of 10-11 at my Tivo, which he said was too high for the CC. They were having problems getting EMM's to activate. He split this line off from the amp (which lowered it to ~2) and installed 2 new multi cards with the latest firmware and I haven't lost a channel in 24 hrs.
