Looked up how to pair my BT headphones to my H7150 and I turned them on successfully but when I tried to back out of the hidden control menu I accidentally changed some settings and I don't know which they were or how to change them back

I'm very upset and am having issues with the tv now...it works but did not detect my cable signal which was feeding into HDMI 3 input. Will the factory reset fix whatever I changed??
Thanks!
