SHARP knows that there is a problem with the LC-37D6U Audio going out and the set that I have was given to me as a gift. The audio had already gone out on it. My friend gave it to me instead of placing it in a landfill somewhere. I am trying to get a replacement AV unit to install in the set and SHARP wants to send me to a repair center. Sharp technical bulletin LCDTV-194 was not sent out to everyone that had purchased the sets and therefore the sets went out. SHARP SHOULD HAVE done a recall on the blessed thing as soon as they found out about the problem or at least contacted consumers and offered a free replacement part. I am very capable of installing a part that simple, however SHARP doesn't want consumers to do such things. I am very dissatisfied with SHARP products and to keep this unit from ending up in a landfill somewhere, I will found a replacement part for it, however I WILL NOT PURCHASE ANY SHARP PRODUCTS IN THE FUTURE. SHARP cannot stand behind their products, then they should not sell them!
