Unplug the TV from the power outlet.
Wait for at least 10 seconds.
Plug the TV back in and turn it on.
This should perform a soft reset on the TV and may resolve the issue of it shutting down after 20 seconds. If this does not work, you may need to perform a factory reset. Please note that a factory reset will erase all settings and data on the TV, so you should back up any important data before proceeding.
To perform a factory reset on your Hisense 55H9F TV, follow these steps:
Press the Home button on your remote.
Select Settings.
Select System.
Select Reset.
Select Factory data reset.
Follow the on-screen instructions to complete the reset.
