LC-37D64U is the TV model number. I downloaded the correct update file and transferred the SAL2A217.UVP file to a USB stick. I followed the on screen instructions to apply the update. The TV was able to identify the file on the USB stick. I proceeded to follow the instructions but I never saw any indication that the TV was actually applying the update. I repeated my process twice without success. I even called Sharp tech support and they walked me through another diagnostic process, then had me apply the firmware update again, no luck !!! I think their software inside the TV is broken and never did work.
