Clearing the cache causes no data loss, but any temporary files must be re-downloaded. Make sure to clear the cache for apps you use frequently like Netflix, YouTube, Hulu, etc.
Periodically clearing the cache helps delete unnecessary temporary files and ensures apps aren’t taking up excess storage space. This simple maintenance can help keep your Hisense TV running smoothly.
Check Hisense TV Remote
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
Having certain picture settings enabled for gaming or fast action content can add latency and lag. Disabling these can help boost responsiveness for a snappier feel.
To optimize picture settings:
- Turn off Motion Smoothing effects like MEMC – These add processing that can slow things down
- Disable noise reduction features – These also add processing lag
- Turn off any contrast enhancers
- Switch picture mode to Game if available – Optimizes settings for lag
- Make sure PC or Game HDMI mode is enabled for the specific port
Tweaking these can help reduce the processing burden on the TV and input delay. You may need to experiment to find the best balance of settings for the content you’re viewing.
Check Wi-Fi Connection
If your Hisense TV is connected to your home network over Wi-Fi, weak or unstable connections can negatively impact streaming and app performance. Checking your wireless setup can help identify and remedy any issues.
Things to examine:
- Wi-Fi signal strength on TV – Should show Excellent or Good
- Distance to the router – Move closer if the signal is weak
- Interference from other devices – Microwaves, baby monitors, etc can interfere
- Wi-Fi band and channel – Switch to the 5Ghz band or a less crowded channel
- Hardwire with Ethernet if possible – Most reliable solution
Improving your network connection can make a world of difference in speeding up buffering, lag, and other performance issues. Hardwiring with an Ethernet cable is the best option, but optimizing your Wi-Fi can also help.
Check for Overheating Issues
Like other electronics, Hisense TVs can sometimes overheat from poor ventilation or excessive dust buildup inside. If your TV feels warm to the touch, this can start affecting performance and cause slowness or freezing.
To check for overheating problems:
- Ensure vents along the back or sides have clearance
- Use compressed air to clear any dust-blocking intakes
- Open up the TV to clean inside with an air duster
- Check the position of any internal fans
