How to Troubleshoot and Solve the Black Screen Problem on Your Sharp TV


Check Power Connection

To ensure that your Sharp 4K TV is receiving power, follow these easy steps:

  • Check the power cable: Make sure that the power cable is firmly plugged into both the TV and the power outlet. If it feels loose, unplug it and plug it back in, making sure it is securely connected.
    For example, if the power cable is not fully inserted into the TV, it may not receive the power it needs. Double-check that the cable is pushed in all the way and the connection is snug.
  • Verify the power outlet: Confirm that the power outlet is functioning properly. You can do this by plugging in another electronic device, such as a lamp or phone charger, to see if it works. If the outlet is not working, try plugging the TV into a different outlet.
    For instance, if the power outlet is faulty, it may not provide electricity to your TV. Connect another electrical device to the same outlet to see if it functions properly.

It is important to ensure that your Sharp 4K TV is properly connected to a power source, as any issues with power supply can prevent the TV from turning on or functioning correctly. By following these simple steps, you can troubleshoot any power connection issues and get back to enjoying your TV.


Verify Input Source

To confirm that the input source on your Sharp 4K TV is correctly set, follow these steps:

  1. Grab your TV remote and locate the ‘Input’ or ‘Source’ button.
  2. Press the button to access the input source options.
  3. Using the arrow keys or navigation buttons on your remote, select the appropriate input for the device you want to connect. For example, if you want to connect a set-top box, select the HDMI input.
  4. Once you’ve highlighted the correct input, press the ‘OK’ or ‘Enter’ button on your remote to confirm the selection.
  5. Check if the input source has changed on your TV screen. If it has, you have successfully set the input source for your desired device.

By following these simple instructions, you can ensure that your Sharp 4K TV is set to the correct input source and enjoy your preferred content without any issues.


Reset TV Settings

If you are experiencing issues with your Sharp 4K TV, we recommend resetting the TV settings to their factory defaults. This can often solve common problems such as display issues, audio glitches, or network connectivity problems. To start the reset process, grab your TV remote and follow these simple steps:

  1. Navigate to the ‘Settings’ menu: Look for a button on your remote labeled ‘Settings’ or something similar. Press it to access the TV’s settings menu.
  2. Find the ‘Reset’ or ‘Restore’ option: Once you are in the settings menu, use the navigation buttons on your remote to scroll through the available options. Look for a section labeled ‘Reset’ or ‘Restore’ and select it.
  3. Follow the on-screen instructions: After selecting the ‘Reset’ or ‘Restore’ option, the TV will display a confirmation message or a set of on-screen instructions. Read the message carefully and follow the prompts to complete the reset process.


  • On some Sharp TV models, the ‘Reset’ option may be located under the ‘Initial Setup’ or ‘Setup’ section within the settings menu. Use the directional buttons on your remote to highlight the ‘Reset’ option and press the ‘OK’ button to initiate the reset.
  • If you have a newer Sharp TV, you might see a ‘Factory Reset’ option instead of ‘Reset’ or ‘Restore.’ Select this option to begin the reset process.

Remember, performing a reset will erase any customized settings or preferences you have made on your TV, so it’s a good idea to take note of your preferred settings or make a quick list before proceeding. Resetting the TV should help resolve many common issues, but if the problem persists, we recommend reaching out to Sharp’s customer support for further assistance.


Update TV Firmware

To make sure your Sharp 4K TV is up to date with the latest features and improvements, follow these steps to update its firmware. First, visit the manufacturer’s website and search for firmware updates specifically designed for your TV model. Look for a support section or downloads page where you can find the necessary files. Download the firmware file onto a USB drive, ensuring that the file is compatible with your TV model.

Next, take the USB drive and connect it to the USB port on your Sharp 4K TV. Depending on your TV model, you may find the USB port on the side, back, or bottom of the TV. Once the USB drive is connected, navigate to the TV’s settings menu using the remote control. Look for an option called “Firmware Update” or something similar.

Select the firmware update option, and a list of available firmware files should appear on your TV screen. Choose the file you downloaded onto the USB drive. Confirm your selection and wait for the update process to begin. It’s vital not to disconnect the power or remove the USB drive during the upgrade as it may cause permanent damage to your TV.

Once the update is complete, your Sharp 4K TV will reboot and display a confirmation message on the screen. You can then remove the USB drive from the TV’s USB port. Congratulations! Your TV’s firmware is now successfully updated, ensuring you have access to the latest features, bug fixes, and overall optimization.

Remember, keeping your TV’s firmware up to date is crucial for the best possible viewing experience and optimal performance. By following these easy steps, you’ll ensure that your Sharp 4K TV stays current with the latest enhancements provided by the manufacturer.
