Just bought W2306C Dell LCD TV-When first connected to Cox-analog cable,several channels come through quite dark as opposed to others which are fine.Resetting brightness etc doesn't get it.I thought it may "need" digital feed so subscribed to same.Still have same problem--"dark" channels.We don't have HD here yet although set is HD ready. I have it hooked up using probably 30feet of regular RG6 coax cable.Do I need to use "digital cable" as opposed to what I used on my other tvs? (I don't have this problem on my 27" tube Sanyo) The Dell is fine,otherwise. Please help!Otherwise,its'OUDDA HEAH! Thank you.
