I turned on the TV/DVR this morning at 04:00 and there was no video, only audio from the Moto 7232. There was no video from the TV channels, menu, DVR, etc. I verified my TV HDMI ports were OK by connecting other devices. I decided to unplug the DVR for 15 minutes. That appeared to correct the problem - all is well now. Anyone else experience this? Did VZ update the firmware on the DVR? My non-DVR STB had no issues.
Have had this happen several times. I usually just turn off the TV, give it about a minute, then turn it back on and the pictures returns. (This has happened to me using component and HDMI connections btw, so I don't really know what's to blame.) Try that next time before unplugging the DVR.
