I’d restart the TiVo and unplug the TV as well. Not sure the age of the TiVo Pace, but it may very well be HDCP 1.4 while the receiver is HDCP 2.2. Issues do come up with the 1.4 devices. They are getting left behind. Sometimes changing UHD HDR settings can help get a picture back from an older device. You would turn off “Enhanced” mode in the TV HDMI settings. You can check the Pioneer’s settings by turning it on and then pressing and holding the “dimmer” button on the front panel. While holding it, press the “auto/direct” button. It will display the current setting, either “Enhanced” or “Standard”. To change it, keep holding the “dimmer” button and press the “auto/direct” button again. Setting the TV and Pioneer to “Standard” mode may work. If not, you would need to leave the TiVo connected to the TV and activate ARC and HDMI-CEC to get audio back to the receiver. Alternatively, you could connect an optical or coaxial cable from the TiVo to the receiver to get audio.
