We had this TV in the garage. My husband brought it in the house tonight. We have to hook up to one of those digital adapters. So we hooked it up. When we try to select source everything by TV is grayed out and it says there is no device attached. The TV does have HDMI ports, but we do not have HDMI cable connecting TV and adapter. We didn't have that in the garage either and it worked, so I'm pretty puzzled right now. However, that's the only thing I can think why we get the message that there are no devices attached and we are unable to select a source. Can anyone help me out with this?
