If resetting your TV doesn’t solve the problem, try updating its firmware. You can find out which version of firmware you have installed by going to Settings > System > About and then selecting Version info at the bottom. 

Once you’ve determined which version you have installed, click on “Version Update” from within this menu and follow any instructions given by Roku for updating its firmware.

Adjust the Screen Brightness of your Onn Roku TV

If none of these solutions work for you, try adjusting your TV’s brightness level manually. 

You can do this by going into Settings > Display & Sounds > Brightness and then either dragging the slider up or down until you find a comfortable level that gives you no discomfort while viewing the screen without causing flickering issues at the same time.

Examine the UPC Code Connection

A simple interruption in signal and transmission between your devices, such as entering a valid UPC code connection, can cause screen flickering with Onn Roku TVs, which rely on an internet connection for streaming purposes.

  • To edit or update these settings, select Setting>Network>Connection Settings>UPC Code Connection.
  • Then enter in valid information matching what was provided on your original device documentation before clicking “Submit,” followed by restarting both devices for best results in getting this glitch fixed.

Double-Check that All Wires are Properly Connected

Another common reason why TVs flicker is because wires may not be connecting properly from outlet sockets into the back ports of devices. 

  • Make sure all connections are secure between input and output jacks! If the problem is still not resolved after double checking that the wiring paths run smoothly without interference interrupting strong signals, then it is time to move onto more complex solutions such as replacing certain parts like bulbs, etc. 
  • Replace any faulty components in the television set. Remove the back covers from the TV set and inspect the inside components, including the monitor’s chipset, connectors, lamps, and so on. 
  • If a part is identified as needing replacement, purchase new items online from electronic store outlets near you with the exact same model letters, numbers, and specifications per manual notes. 
  • Install parts slowly and safely, making sure no other problems arise mid-installation process, either by restarting the television or returning it to regular viewing soon!
