If certain buttons on your Hisense TV remote are unresponsive or intermittent, it can make navigating the smart TV system feel sluggish or delayed. Try the following tips to check the remote:

  • Check the batteries are fresh – Replace batteries if they are low.
  • Ensure the remote sensor on the TV is unobstructed – Remove any obstacles blocking the sensor.
  • Check for interference from other devices – Turn off nearby Bluetooth or wireless devices.
  • Try re-pairing or syncing the remote – There may be a button combination to resync with the TV.
  • Attempt resetting the remote to factory defaults – Consult the manual for the reset procedure.
  • Update remote firmware if available – Some models can receive remote software updates.
  • Test buttons with remote diagnostic app – This can pinpoint unresponsive buttons.
  • If certain buttons still don’t work, the remote may need repair/replacement.

Close Background Apps

Having too many apps running in the background can sometimes bog down the system, leading to choppy playback or lagging navigation. Closing unused background apps can help free up memory and processing power for a quicker experience.

To close background apps on Hisense TVs:

  • Go to the app switcher menu, usually by double pressing the Home button
  • Swipe up on any apps you want to close
  • Or select Close All to force stop everything not currently in use

This simple process forces inactive apps to close, preventing them from taking up resources. Just be careful not to close apps you still need! You may have to do this periodically if performance drops over time from too many apps accumulating.

Adjust Picture Settings
