The tv was connected to the laptop(HP envy x360 m6 with Intel he 620) when the tv screen went black. It kept saying no signal but the sound still works. The tv also used to be named Panasonic th-46pz80u under device manager but now it just shows 2 generic pnp monitor(one of them is the laptop screen itself in guessing). I've tried uninstalling the Intel hd drivers. I also tried rebooting and resetting(did the delete everything option) under Windows recovery.
Also the HDMI output was working fine for months.
