    He says he's already tried several HDMI cables. Unless they are all came from the same source, it's very unlikely they are all bad or are all out of spec.

    Which is not to say that you should not always eliminate the cables first, even when it's unlikely to be the problem. But I think he's done that.

    Update: I ordered brand new high-quality HDMI cables. No difference.

    I chose "Set Top Box" and went thru the choices to select TiVo and FiOS. It still says "No signal" in all the setup screens, then after all setup is done asks me to ensure the TiVo is on, because it sees no signal.

    TL;DR: No change.

    I didn't read super close, did you ever have your Roamio HDMI port connected to other displays to confirm it is working, maybe a small monitor with HDMI input?

    I'm not familiar with the Roamio's so the cables that you ordered, were they certified high speed cables, the ones I linked to above?

    I have the TiVo Bolt+ and had issues with cables with my LG OLED B6. Also with Apple TV, Nvidia Shield and Amazon Fire tv until I got those cables.

    If so, perhaps you have a bad hdmi board in either the TiVo or LG?
    Also the way you power on the devices can cause issues.
    You're not running through an AVR are you? That can cause issues too especially if it's a Denon.

    Update: Took the TiVo to the neighbor's house. It would not display any output via HDMI to his TV either. Looks a lot like the HDMI chip/board/circuit in the TiVo went bad.

    Again. This is *exactly* the same problem I had with my TiVo HD, which is what led to my buying a Roamio Plus.

    What would you guys do? I can watch through component video but it's notably lower quality than HDMI. Which is especially noticeable on the brand new 4K TV. I'll get a repair/replace quote from TiVo so I know my options, but I am feeling a bit like "fool me once, shame on you; fool me twice, shame on me." That is, I'm hesitant, after having two TiVo's with the exact same HDMI failure, to put more money into TiVo. At least the HD lasted 6 years, but this Roamio is only 18 months old.

    Are TiVo's known for HDMI issues or am I just very unlucky?

    I would be surprised to see component be noticeably lower quality than HDMI at 1080i given that's the max resolution of any cable channels. You are using the component output and not the composite output next to it?
