A JVC LCD flat-panel TV can be updated to include new features. You can update the firmware on the JVC LCD yourself. The firmware update can be downloaded from JVC without cost and transferred to a flash drive. The flash drive can then be connected to the JVC LCD, and the firmware uploaded to it. The procedure does not violate any warranty that might be in place and does not require any special skills to execute.
Download the appropriate firmware for your JVC LCD flat-panel TV from the JVC website (See Resources). Double-click the file once downloaded to decompress it onto the desktop.
Insert the connector of a USB flash drive into a USB port on the computer. Drag the decompressed firmware file onto the icon of the USB flash drive when it appears on the desktop. A copy progress bar will appear, fill in from right to left and then disappear.
Right-click the icon of the USB flash drive. Select "Eject" from the pop-up menu. Remove the USB flash drive from the computer's USB port.
Plug the USB flash drive into a USB port on the JVC LCD flat-panel TV --- the USB port might be on the front, beneath a hidden panel, or on the side or back.
Turn on the JVC LCD with its remote. Press "Menu." Select the "System Setup" menu. Select "Firmware Update" or "Update Firmware" from the list of choices presented. Press the "OK" button on the remote when the new screen appears. Select "Yes" on the confirmation window that appears to begin the firmware update.
Press the "OK" button on the remote when the confirmation window appears that states that the firmware update is done. Turn off the JVC LCD TV with the remote.
A power failure that interrupts the firmware update can cause the JVC LCD to exhibit problems afterward.
