Sharp manufactures some of its television models to allow owners to periodically upgrade the software for online diagnostics, video-streaming applications and other functions. Upgradable TVs, such as the Aquos line of LCDs, have USB ports to provide an easy way to install updates. Sharp makes the most current version of the firmware available for free on its website.

Step 1

Go to the Sharp Product Downloads page, use the drop-down menus to select the model of your TV and click the “Search” button. Click the “Firmware” link on the list of results to download the file in ZIP format.

Step 2

Insert a flash drive into the USB port of your computer. Go to your Downloads folder, and right-click the firmware file. Select “Extract Files” to open the “Extract To” window.

Step 3

Click the icon for the flash drive to select it as the extraction destination, and then click “OK.” Click the "Safely Remove Hardware" icon in the System Tray once the extraction process completes, and take the flash drive out of the computer.

Step 4

Insert the flash drive into the USB port on the TV.

Step 5

Press the “Menu” button on your remote control, and use the directional buttons to navigate to the “Information” option. Press the “Enter” button to open the submenu.

Step 6

Select “Software Update,” and enter your four-digit security code.

Step 7

Choose “Manual Update,” select “USB Memory” and press the “Enter” button.

Step 8

Press the “Enter” button once the TV locates the firmware files on the USB drive to start updating. The TV will restart itself at the end of the process.

Step 9

Press the “Enter” button when the TV turns itself back on to complete the firmware update. Remove the flash drive.
