Just picked up a 60" sharp aquos LC-60LE832U from costco. I had a samsung 58" plasma before but had to return it cause apparently im very sensitive to the "rainbow" effect while watching it. Anywhoo. My condo has basic cable included with the unit and with the samsung i was able to simply hook the cable up directly to the Tv and get a a few hundred channels both digital and analog. However with the new sharp tv, no channels are being detected, even switching between "cable" and "air" in the settings. Anyone experience the same problem before?
