Sorry to heat that Art Mode not working when you navigate to the home screen it goes completely black screen.
If your TV stops displaying art while Art Mode is activated, it could be because Night Mode is enabled. Turn off Night Mode: Scroll all the way down to Art Mode Options, and then highlight Night Mode. Press Enter on the remote to switch Night Mode from On to Off.
You can also try Resetting Smart Hub. Settings > Support > Self Diagnosis > Reset Smart Hub. Please note that this will reset all apps.
After the reset, turn tv off and unplug the power for five to ten minutes and try again.
