I have a mag254 that was working until the end of trial. When they ended the trial a message came up "no signal" When rebooted the informer splash screen came up "loading", but never actually loaded. Came up "no signal" splash screen was snowy (bad signal). Looked like a bad HDMI port, so I changed to the y,r,w cable and get the message "not supported change to HDMI". Now normally I would be able to change that setting, but I can't get to the default portal to chane it. Any ideas? Even if someone could tell me how to get to system settings to change the display.
