Jane M. Posted January 5, 2020 Share Posted January 5, 2020 i have a C4 8x8 Video Matrix and it’s connected to 2 Verizon Fios Cable Boxes, 2 Apple TV’s and 2 Direct TV boxes. For months everything has worked fine but suddenly last night the two Verizon Fios Cable Boxes started to show only static on my TV’s. At first I thought it was a glitch and I rebooted the Matrix and eventually the entire C4 rack of equipment and the cable boxes, but the issue persisted. (The Apple TV and Direct TV sources show up correctly). Then I thought maybe the issue is the two hdmi ports the cable boxes are plugged into went bad. But when I plugging the Apple TV into the Verizon Fios hdmi port on the Video Matrix, and it shows up properly. So clearly there is an issue that is specific to the Verizon Fios Cable Boxes and the C4 Video Matrix. Again, what I see on the TV screen is total static. Any ideas how to fix this?

c4toys Posted January 5, 2020 Share Posted January 5, 2020 is this old style tv static(black and white) or a bluish color static.. bluish static is caused by HDMI handshake issues, cable box are the worst for handshake issues Quote Link to comment Share on other sites More sharing options...

Topfox Posted January 5, 2020 Share Posted January 5, 2020 For what it’s worth, I have an 8x8 Matrix as well and I have 4 Fios quantum boxes (smaller ones) hooked up to mine and am not having any issues. Quote Link to comment Share on other sites More sharing options...
Jane M. Posted January 6, 2020 Author Share Posted January 6, 2020 It’s a blue red white static. But yes, a blue hue. I also plugged cable box straight into tv (bypassing matrix) and it worked fine. So it’s definitely a matrix sync issue of some sort. Question is what did Verizon push out and how do I fix it? i have newer Verizon Fios One cable boxes.

lippavisual Posted January 6, 2020 Share Posted January 6, 2020 Recalibrate the matrix? Quote Link to comment Share on other sites More sharing options...
Jane M. Posted January 6, 2020 Author Share Posted January 6, 2020 I assume to recalibrate the Matrix, I need the C4 dealer? I wish they made certain functions available to the End Users! Quote Link to comment Share on other sites More sharing options...
lippavisual Posted January 7, 2020 Share Posted January 7, 2020 Could do it if you had HE I believe Quote Link to comment Share on other sites More sharing options...
Jane M. Posted March 6, 2020 Author Share Posted March 6, 2020 Dealer re-calibrated my Matrix and now the Verizon cable box works property. But there is conflict between the C4 Video Matrix and the Verizon cable box. C4 needs to fix! Quote Link to comment Share on other sites More sharing options...
Topfox Posted March 7, 2020 Share Posted March 7, 2020 Ive ran into this issue recently, however all I needed to do to fix it was boot the FIOS box up directly wired to a TV over the HDMI. Then I reconnect it to a the matrix switch while it is still plugged in, and then I power the Matrix switch back up. Ive found I need to do this 1 at a time. There is definitely some timing, handshake issue going on here. Its popped up to be a few times over the last two months, usually after a hard power outage.
