2. Unplug the TV from Power!
The Hisense Roku TV black screen issue might be a temporal fault and hopefully can be fixed by unplugging the TV from the electrical outlet.

Follow these instructions to conduct a power cycle on the Hisense Roku TV:
- Press the “power” button on the Roku TV remote control.

So, press any of the platform buttons and determine if the Hisense Roku TV will alter the sound output in any way and whether it will open up the platform.
If the TV recognizes the button press, the audio of the TV should stop as soon as you hit any of these stream buttons, switching from one app to another!
Tip: Test all four of the platform buttons!
4. Unplug Third-Party Video Feed
The problem might be originating from a software conflict caused by a connected third-party device.
TV speakers, gaming consoles, satellite boxes, and even streaming sticks could result in a potential display malfunction while their source is selected on the Hisense Roku TV.
