I was given a beautiful 37 Inch LC Sharp flat screen TV but it only works with this AVC unit that comes with the TV. This AVC Unit was apparantly destroyed in a move so it's not available. I called Sharp and as it was a TV that was made in 03, the AVC unit is no longer available as they don't make it anymore. My question... is there a way to get the LC tv to work without the AVC unit? My model number is Sharp LC-37HV4U. Thanks!
