    After setting up my new Roamio in the bedroom and using it for a couple of weeks I decided to switch it to my main Samsung 65" TV in our Great Room. I am now experiencing problems that I never had with the HD unit that it replaced nor while the Roamio was connected to my Westinghuse TV in my bedroom.

    The problem is that when I switch between various menu options, the TV loses the signal from the Roamio and waits for about 20 seconds before it picks up teh signal from the Roamio and reconnects.

    Is there some setting on the Roamio that I need to change? Again, this never happened with the HD unit on the same TV nor did it happen with the Roamio connected to another Tv in another room.

    Any advice?

    Is it changing display resolutions?

    Just set it to output 1080p/60 and 1080p/24 and you won't have this problem.

    What resolutions do you have enabled? What I meant in my previous post was to only have those enabled. I suspect that when you are an HD menu screen and then open up an SD menu screen, your resolution is changing. Not all the menus in the Roamio are HD.

    I tried just 1080i and that gave me the same results as when I ran through the compatibility tests and allowed all but the lowest setting which was not compatible with my TV.

    I think you guys are missing my point.

    My OLD Tivo HD was locked on 1080i and worked fine. My new Tivo Roamio loses the picture when I switch from most any menu option to another menu option OR to a live picture. It seems as if the TV loses the picture then needs about 15 sec to sync back.

    I've tried locking it on everything from 720 through 1080p all with the same results. I also set it to "auto." Again all with the same results.

    The TV can handle everything from 720p through 1080p and everything in between.

    The TV viewing is fine it's just that hesitation in the beginning when it loses the signal then needs time to synch back up before the picture comes back.

    I think I'm having the same issue(s) with three base Roamios and two Sony TVs.

    Even though I set the Roamios to fixed 1080i (or 1080p) ONLY, as the fixed output (plus checking the 1080p/24 passthru for Netflix), my TVs "freak out" while navigating, or during commercial transitions, or if any little issue arises in the cable signal, and so on...

    The same TVs handled TiVo HDs and Premieres without this problem. All possible troubleshooting has been done. I'm not going to spend another hour going into great details about everything I've tried.

    I've lost hope... All I can do is keep bringing it up when I see a similar post by another member...

    No matter what thread I bring it up in, all I get are people who tell me they don't have this problem. Well, that's just great... I'm so happy for all the people that don't have the problem. I then politely say that I'm looking for others having the problem, or people who had it and somehow fixed it. Then, things go silent (for this specific issue)...

    Funny thing is, these same Roamios didn't used to have this problem. It presented itself in a previous software update, and has persisted ever since...

    I'm not going to buy new TVs, when the literal dozen other HDMI devices I have around, work just fine with what I have. The Roamios are the ONLY "problem childs" in the mix. If I could get ONE other HDMI device to act the same, I'd think differently.

    I guess I have to buy some inline device to "correct" whatever the Roamios are doing with the HDMI signal, or live with it, or just wait and see what future software brings. I've tried switches in-line, and they'd fail to re-sync at all, requiring me to switch away from the input, then back to it again, just to get more than a black screen, and no audio.

    My TVs have a way to show the current resolution and audio mode, with a single remote press, and that data goes blank when this happens.

    Good luck in your quest... I'm subbed to ~10 threads where any similar problem is mentioned, and this is the only one with any recent activity...

    FWIW, it seems most people speaking of similar issues, have an A/V receiver in-line, while I don't (and you don't, if I understand correctly).

    another "i don't have that problem" post, but...

    I have the roamio pro, hooked up using hdmi though an onkyo receiver via hdmi (although a/v is usually off and just in pass thru mode), then hdmi to my samsung ln46a650.
    I only have 1080p/60 and 1080p/24 enabled, everything scales nicely.

    It kinda sounds to me like there is an HDMI handshaking issue going on possibly? my sony bravia was doing some crazy things like you guys have mentioned and I'm not sure about samsung tv's but what I was able to do with my Sony Bravia was do a firmware update and then after the firmware update to the tv I unplugged the tv and then unplugged each device I had connected to the tv and let them reboot; I haven't had any issues since....also I'm wondering if you guys tried using component cables? sometimes that can fix a lot of problems with HDMI handshaking...

    If you are using component cables, then that should fix ALL of your HDMI handshake issues. Switching to component cables is a very good test to help rule out HDMI handshake issues.

    tarheelblue32 I agree 100%....it does sound like their issues are an HDMI handshaking problem and like you said trying some component cables would be a good place to start for some good troubleshooting.....also some TV manufacturers have firmware updates.....I know my Sony Bravia did... I bought my Sony TV in 2010 and there had been a firmware update in 2011; I updated the firmware and unplugged everything as Sony suggested doing and letting everything reboot which basically reset the HDMI and since then I've had no issues.....

    Base (4-tuner) Roamios don't have component-outputs. It's either HDMI, or buy a composite analog A/V breakout cable.

    The Sony Bravia TVs have the most current firmware. They used to work just fine with my Roamios, and all the eight TiVos I owned before them.

    One of TiVo's software updates caused the problems, for me.

    Even if I had a Plus/Pro, and the component worked, I'd want to use HDMI. Component-out can't match HDMI quality. It's digital->analog->digital conversion, and component doesn't carry audio, creating a whole new problem, with using analog for audio, or having to buy optical cables, which I have only one input for.

    Really short summary: Something TiVo did for the majority of people, has created adverse effects for a minority of people. TiVo seems to always do this, as soon as I dare to think "I'm so glad I upgraded to my new model TiVo!". Sometimes they won't fix something, if the minority is small enough.

    Perhaps with all their MSO partners, this could change. Yet, I have very little faith, as my cableco is also guilty of not being willing to fix things that only affect a minority of their customers. I'm not even sure any MSOs use base model Roamios.

    I spent all that time helping you in your MoCA question thread, and you assume I haven't tried power cycling and every other possible thing that may help? If I troubleshoot any more, I'll wear everything out from all the repeat disconnections and reconnections.

    nooneuknow; yea you're right I forgot the base Roamio only has a composite output...the problem I was having was on a mini which has both component and composite outputs.....doing the firmware update and unplugging the TV and all connected devices so that the HDMI would reset did fix a similar issue for me but apparently there is something different going on with yours and the OP Roamio's....sorry I couldn't help; the advice you gave me on my MoCA setup helped a lot! I took your advice and just left everything alone, kept my CMG in bridge mode and it has worked just fine with no problems.....

    Good to hear, on your end of things. :up:

    Sorry for snapping at you. I was just suffering a burst of HDMI sync losses, and was wishing I could at least try component to see what would happen. But, I can't... I need OTA capability, should I have to move, or save money, which is why I went with the base models.

    I participated in the thread the OP of this thread used for their drive upgrade, and recall it being a base model, as well, IIRC.

    If TiVo doesn't fix it by the summer update, I'll (possibly) be known as "tivousernomore". I've been tackling every possible scenario that I can, without buying more TVs, and am drawing a line. I was hoping the spring update might improve, or fix what they messed-up. It made it worse. I had been getting along with setting the output to 1080i, since the original update (can't recall the version) that made problems for me (with it set to 1080p).

    I'm talking three Roamios and two Sony TVs, of different years and models. I can hook up any other HDMI device, at any resolution supported, and they'll work on both TVs, on any HDMI port, and all my other HDMI devices work through HDMI switches, as well. Only the TiVos are refusing to keep the HDMI up constantly/consistently. I could pull the cable feed, turn-off the video window, and still lose the HDMI sync just navigating, and even when sitting idle. Yet, my WD TV Live Hubs, with v1.4 HDMI-outs can be attached to the ends of the same cables going to the same TVs, and flawlessly send full 1080P/60 and 1080P/24 (and every other resolution down to 480i), and never once do what the Roamios do...

    Hinky, and odd, I know... But, it's the truth...

    So I'm assuming you tried different HDMI cables? I've seen bad HDMi cables cause those issues. I've run across it a few times. When I do I just cut the cable and throw it away.(even though the cable might work perfectly fine with another device, it can have issues with a certain device)

    What about an active HDMI splitter? Leaving one output empty and the other going to the TV.

    This must be directed at the OP, since you've been present in, and commented in, some of the other threads I've discussed this in.

    As for an active HDMI splitter, I'm done buying any more items that won't guarantee results (or doing what the product claims it will). Some of the switches I bought sounded promising as a kludge-fix, since they have "stabilizing, upscaling, and signal enhancing" as an optional functions to turn-on (even upconverting to 3D is one of the options). They won't play well with the Roamios, no matter what I set them to do. At least they work with everything else I own, leaving me able to direct-plug the TiVos into any two of the three HDMI ports on each TV.

    I bought excess cables and switches I have no use for now, just trying to "try it all".

    Since I have zero use for a splitter, other than as a diagnostic "desperate measure" tool, I'm unwilling to spend any more money on things that might work, until two updates from now, if/when TiVo decides to make more changes.

    I'd feel bad giving out suggestions like switches/splitters/matrixes, without making sure to say such devices often cause issues, rather than fixing them. I'd also express concern over some future update rendering that device incompatible, or the first thing everybody will want to blame as the source of a problem (then giving advice to remove it, and TiVo support refusing to provide support with it in use).

    I'll be back later, to add a list of links to my long and detailed posts I already have peppered throughout the forums on what I have tried.

    Hey bud no problem I didn't take it that you were snapping at me...I just thought maybe that suggesting a firmware upgrade to your Bravia may help ya but I've done seen how knowledgeable you are on this Tivo stuff so I sure wasn't suggesting that you just reboot your devices lol I knew you would have already done all that stuff and lots more trying to solve your issue and I wouldn't insult your intelligence by suggesting you do generic things, lol....I thought maybe the OP could use component cables but then I hadn't realized that he too was using a base Roamio.... you really gave me some great advice on what to do for my MoCA network and trust me I took it and its been just fine so far.....its really odd how you and the OP can have that issue yet a lot of others don't? seems like it would affect all of us but I'm sure its probably due to some software glitch as you suggested and hopefully Tivo will send an update that will resolve it for ya.... I wish I could have given you guys some better input but I just haven't been a Tivo owner long enough and know enough about them yet..I can only relate to the few problems I've had with mine so far..

    I am having the same problem with Roamio Pro and my 5 year old Samsung. I have been gone for 2 weeks and TiVo did a software update while I was gone. I have done a s/w update on the Samsung TV, swapped HDMI cables, swapped HDMI ports, all to no avail. Finally I connected component cables, which has resolved the problem, but not with the resolution I bought the Roamio for. TiVo support is "not aware" of the problem and has resolved it's only solution is to send me a new unit.
    I have a TiVo HD hooked up to the same TV and no problem.
    Before the Roamio software update (20.4.1), there was no problem. Obviously a new Roamio unit (with RMA fee) is the only solution ;-p
