My kids switch no longer outputs video from the Dock. It will try to output and physically turns on the tv with HDMI sync when enabled. I've tried multiple TV's and they all detect a device on the port but still no video. This also only happens if the switches screen happens to be turned on when I put it on the dock. If the screen is off it will not send the signal to the tv to turn on and the tv detects no device on the HDMI port. I don't have another switch to try with the dock but it almost seems like the dock itself is fine. I found this old thread https://gbatemp.net/threads/switch-with-no-display-on-tv.552653/ and am wondering if this could be the culprit or if there is something else I should look for?
