I have a 2 year old Sharp Aquos tv. The model of the unit is lc-30hv2u. For the unit to display tv it requires what they call a AVC unit. During a recent move we managed to loose a few boxes and the AVC unit is gone. I have tried to purchase a replacement unit from Sharp and have looked all over the internet have found nothing. Sharp states they do not sell the unit seperatly. Does anyone have any idea as to how I can watch tv on this unit again? Currently I have it hooked up to a computer using a dvi cable from video card to TV to watch DVD's, Works great. I tried to get a tv video card but it's aweful looking. Thanks for any assistance.
