    Well, since putting a fan under my Bolt it had been working fine until yesterday, when once again there was no signal out of the Bolt to my TV. Restarting the Bolt fixed things and I immediately checked the temperature which was 53 Degrees C, so it certainly didn't overheat. I'm starting to think the issue is something different now.

    My Bolt just lost the signal to my TV again! Rebooted the box and the signal was back, the temp was 51 and definitely not a heat issue now.

    Does anyone have any suggestions for a fix? Could it be my brand new LG OLED TV causing the issue? Or maybe the cable from the box to the TV? Or is the Bolts HDMI or TV tuner going bad?

    Happened yet again when I turned my TV for the first time today. This is becoming a daily thing now. WTF!

    I've never had such issues but I guess you could try attaching another TV when it's in this bad state. Can you try another HDMI cable, maybe a shorter one? Is there another HDMI input on the TV you can try?

    Do use standby or any of the power savings modes (Tivo Customer Support Community)? I don't. It's power saving off or me.

    I go thru an old Yamaha receiver and there is a Yamaha receiver related handshake bug (the workaround about changing a setting on the receiving is ineffective). Basically, if I power on my TV and receiver too close together in time, IIRC, the TV will fallback to 720p. If want want 1080 res, I have to change TiVo's video out setting back to 1080i or 1080p. To prevent this, always have to power one on, wait several seconds then power on the other. My TV's very old though, a Samsung HL61A750 circa 2008.

    It kept happening to me as well until I figured out a way to avoid it. I always turn on another device (input) first, then I go to the one with the TiVo. It seems to work this way so that I avoid the "no signal" issue.

    Found a thread here with others having the same issue with their Bolt and LG OLED TV, it was suggested to turn off any power saving mode on the TV. So far that seems to be working.

    Most of the time (I'd say about 75%), my TV reports no signal from my Bolt. I switch the TV to another input, then switch back, and that gets it working.

    My TV is about 12 years old, and I suspect that its HDMI support is not fully compliant; or that the Bolt is relying on some perhaps optional aspect of HDMI compliance; I found that a Chromecast would not work on this TV, either. But my Tivo Premiere always worked fine, right up until it died a few months ago.

    I've become so used to doing that so that every time I want to watch the Bolt, I automatically turn on another input (or Activity with the Harmony remote) first and then go to the TiVo activity 2nd.
