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 fifty-fifty called Sharp tech back up and they walked me through some other diagnostic process, and then had me utilize the firmware update over again, no luck !!! I call back their software within the Telly is cleaved and never did work.
