On many occasions it is not necessary to have to go to the technical service to solve the failures of YouTube, Netflix or any other streaming application pre-installed on our HiSense TV with VIDAA operating system.
Given the scarce storage space they have, compared to other computer equipment, it is possible that the navigation data used by these applications has filled their cache memory, making it necessary to renew it. The procedure is very simple. You just have to follow these steps.
How to fix YouTube problem on HiSense VIDAA TV
Using the remote control, access the HiSense TV home screen. Go to Settings > System. Then select App Settings.
On the screen that appears, select Clear Cache and confirm the operation using the OK button on the remote control. The TV will restart automatically.
