Short hdmi pigtail on back of controller has bad connection

I’ve been having trouble with the monitor of my Onefinity losing the signal while in use. It started doing it more frequently until it didn’t receive a signal at all , A “no signal” message would appear. I found out if I wiggle the hdmi that connects to the back of the controller box it would get my signal back but it is getting worse. The monitor works, the controller works. I believe the short hdmi pigtail has a bad connection.

Hey Robert,

this could be the monitor intermittent issue that is solved by placing ferrite cores on the HDMI cable, see here
