Hey there guys i just purchased a 52 sharp AQOUS LCd and i hooked it all up yesterday. I have direct TV hooked up to it and and when i search the channels the HD channels dont come up. I even tried to hook up a regular antenna to it to see if it can pick up any channels. I have that antenna hooked up to another lcd (LG 22") and it picks up all the channels. So if there is something specific that i need or im not doing, please let me know im going nuts......
