Standby changing from red to white but screen stays black
My sharp smart tv model 40BJ3KF2B is not turning on. The standby light changes from red to white but the screen is staying black. The TV itself doesn't have any buttons on it. It was working fine last night, I only bought it about 2 years ago, brand new. I live alone so I know no-one has been near it. I turned it off at the wall for 30 minutes & it's still doing the same thing. Can anyone please help me?
