Lost display on my tv overnight

Hey all

Been running one of my majaro installs on an older Toshiba amd-a6 laptop in the living room and for the most part has been great. This morning though, I woke up to the monitor not turning on and the tv saying ther is not signal. Restarted a few times. When I boot up, I see the splash screen loading then a few seconds into the desktop it just stops displaying.

I unplugged the tv from the laptop and the laptop screen came back on. But I cant I figure out how i can reset all the display settings to get the tv to display again. Everything works fine with a live session so im not sure exactly what happened over night to cause this.

Im running manjaro KDE on Linux59 if I recall.
