Hi, I am using an Arris gateway portal connected directly to a non-HD Sanyo TV (via RCA cables) and an HD Sony Playstation monitor (via HDMI cable). For months this setup worked fine without problems. I could display video with audio on one TV or the other or both simultaneously.
Then last Saturday, my HD Sony Monitor would no longer receive a signal (video or audio) from the Arris Portal, however the non-HD TV still connects and functions normally. When I turn on my HD Sony TV or switch to the correct input while the non-HD Sanyo TV is on, the video on the non-HD TV flickers off a couple times and the audio may cut out temporarily which tells me that the Arris portal is detecting the HD tv, but not completing the connection.
I think switching to component cables may fix the problem, but I have none to test with.
I have tried the following solutions with no success:
-Powering off and on of the Portal
-Holding the Reset button for 6 seconds to reset the portal
-Adjusting the resolution settings in the Settings menu
-Swapping HDMI cables
-Changing the HDMI input
-Turning on and off power standby settings on HD tv
-Turning off and on HDMI control settings on HD tv
Any assistance will be greatly appreciated!
