Hisense Roku TV is unlike the other Android smart TVs. This runs in the Roku OS and it consists of some of the incomplete issues with the firmware on the Hisense Roku TV. There are some reports from the users that not working of the apps properly on the smart TV. And also there will be frozen screens and remote glitching when using the Hisense Roku TV.

If you come up with these issues on your Hisense Smart TV, the best fix is the clearing of the cache data. The Roku does not store cache but Hisense Roku TV uses a lot of memory for its design.

Factory reset is another solution to clear the cache on the Hisense Smart TV.

You can follow the below steps.

1. Press the home button on your remote control. This will open the main menu.
2. Press the arrow buttons and navigate to the Settings.
3. There, Click the System
4. Then select Advanced System Settings.
5. Click the Factory Reset option.
6. After clicking on it select the option Factory Reset Everything.
7. Then you will see a code on the screen and input this code.
8. You will get a confirmation on the screen. Confirm it and wait for the smart TV to get reset.
9. After the end of rebooting your smart TV, you have to configure the Hisense smart TV.

This model set had defective LED lamps from the factory and only lasted 1000 plus hrs...You can get lamps that will last from shopjimmy that will fix the issue for about $60 with shipping. Its not a hard job changing them, just takes some patience and care when handling the screen as it's extremely fragile on most lower price sets.

First make sure that you have the antenna connected to the RF jack. Go to the Home screen of the TV and select the Antenna TV tile on the right hand side of the screen. (If you acquired the TV from a previous owner, they could have hidden this tile. See the steps preceded by Otherwise.) If this is the first time you scanned for channels, just follow the onscreen prompts (including setting your time zone). Otherwise, go to Settings (below Home in the left column on the home screen) > TV Inputs > Antenna TV > Scan again for Channels > Start finding channels. Use the arrow keys to navigate the menus/tiles and press OK to enter. To save, make sure to select Done and press OK.
