Omg!! Thank you so much sir! You saved me from having to pay someone to come out and check! My tv had not been coming on for over 2 months! Blessings to you! Ty sooooo very much!!
Thanks studio 6060. Going into app settings allowed me to fully uninstall and reinstall discovery plus, or any other app. I deleted alot of preloaded apps that Samsung applied to the TV when it was bought.
