3. Update the Firmware of your TV
If you’re able to interact with the TV with the current condition of the picture, you should perform a firmware update to the latest available version.
The Sharp TV might be experiencing bad picture quality or the inability to tweak the settings because of a bug with the operating system.
- To update your Sharp TV, the device must be connected to the internet!
Here are the simple steps to update a Sharp TV’s firmware:
- From the home Sharp TV page, head into Settings.
- Press on “Setup” and scroll all the way down in the tab.
- Access the “SOFTWARE UPDATE (NET)” tab next.
- Follow the on-screen instructions to update your TV.
Note: Updating the firmware of your Sharp TV may require a little time but be sure not to press any buttons on the TV until the update is completed.
4. Revert to a Different Input
If there’s an issue with the physical input on your Sharp TV, the problem will be visible on the respective viewing source.
This only applies when using your Sharp TV to watch the broadcast of a TV box, a gaming console, or perhaps a computer via HDMI or other video transfer cable.
How to Revert to a Different Input?
Unplug the cable of the third-party device (the cable box or gaming console) and search for an alternative input, available on the back of the TV.
Plug the cable of the external device tightly into the new input and select the correct source from the “Source Menu”.
How to Adjust Sharp TV Viewing Source:
- Press the Source button on the Sharp TV remote.
- Locate the name of the input on the back of the TV.
- Example: HDMI 1, 2, or 3 – Component – RCA
- Highlight the source with the remote and press “OK”.
- Check if your Sharp TV will still have picture issues.
Tip: You should test out all of the available inputs on your Sharp TV, compatible with the external device’s video/audio cable.
5. Unplug All External Devices
If you’re using the Sharp TV to watch the broadcast of an external device, the problem might not be with the TV, but with the third-party device instead.
To test this out, you must unplug all video cables plugged into your TV such as HDMI, coax, or component cables, RCA, and more…
Unplug all of the following devices from your Sharp TV:
- Gaming consoles (PS4, Xbox, Nintendo Switch)
- Cable or set-top (satellite) TV boxes
- Digital antennas or other tuner devices
- Computers or laptops plugged in with an HDMI
Alert: Keep all of the devices disconnected from your Sharp TV until the end of the guide!
6. Check for TV Overheating!
If your Sharp TV’s internal temperatures have been rising for a while, the TV’s picture may start reacting to the heat that’s building up.
The symptoms on the picture as a result of overheating are also known as “ghost spots” and could make your viewing experience terrible.
What Causes a TV to Overheat?
- A heat conductor close to the Sharp TV
- If your TV has been working for a long time
- If there’s direct sunlight shining on the TV
- Dirt or debris on the TV’s ventilation vents
- Dusty spot or surface that your TV is on
Tip: Check if your Sharp TV’s ventilation vents are completely dust-free, since if the air path is interrupted, there could be severe consequences for the TV due to overheating!
7. Restore the Initial Settings on the TV!
Perhaps, restoring the default settings on your Sharp TV may help with whatever picture problems you’re having.
The “factory reset” is a setting that allows the TV to revert to the default values for all settings by cleanly reinstalling the operating system and updating it.
Follow these steps to factory reset your Sharp TV easily:
- Press “Menu” on the Sharp TV remote control.
- Navigate to the “Reset” section of the settings.
- Press “Yes” on the popup confirmation screen.
- Wait for the factory reset on your Sharp TV to start.
Alert: The factory reset erases all content saved on your Sharp TV, including movies, music, data, configured settings, and cache.
