I have a Sharp Roku TV model LC-65LBU591C. It got a software update through the settings menu and after it was completed successfully, the TV restarted and after showing the logo, the Live TV pannel appeared asking to connect an antenna and search for channels. If I choose to cancel, nothing happens. I cannot skip to the home screen or go to the settings or anything else. It always shows the Live TV panel. I never used the TV Live option and I don't have an antenna. I use the TV mainly for presentation through HDMI cable. I wonder if this is a bug with the software update and how I can resolve this issue.
PS: Reseting the TV by pressing the reset button at the back of the TV did not work. Plugging out the TV for a few minutes and pressing the power button for 15 seconds also did not work.
