I am having issues with several Fios boxes connected to our living room TV. For years we had a Fios DVR box connected here but a couple weeks ago started having issues where the picture and sound would not come up when turning the TV on. After extensive troubleshooting with several techs via chat and phone, resetting the box and the FIOS router, they concluded that the DVR box needed to be replaced. Upon connecting the new DVR box the issues persisted.
A tech then suggested switching the DVR with a One Mini box in another room. Once I did that I had a new issue in the living room. When I turned the TV on I would get a green screen with no sound. The DVR now in another room has no issues I experienced when hooked up in the living room.
Next I switched out the HDMI cable 3 times but the green screen persisted. Then I tried all 4 DHMI ports on the TV with the same results.
In every scenario I have to reboot the Fios box to get picture and sound.
As far as I see it I have ruled out Fios boxes and HDMI cables. The WiFi connection is good according to the Fios system info screen on the One Mini box.
One thought is the TV is having HDMI issues, but I have a DVD player and an AppleTV hooked up to it and have no issues with either of them.
Anyone have any suggestions on what else to check?
