Advertisements All of a sudden, no signal. Rebooted. Changed HDMI cable input. Switched HDMI cable. Unplugged everything except Tivo and HDMI to TV. Still nothing. If I try to use Tivo remote, I see lights blinking on front of Roamio, but still no video signal. UPDATE: couldn't use component connection as my OLED TV in living room has only HDMI. So, brought the Roamio Plus to the basement and connected there. The component connection is working on the Tivo so I could at least use my Roamio. Did call Tivo and they couldn't help but offered a Bolt replacement (for a fee of course).
