Hi I have just purchased this tv and a dmr-83 eb-k recorder and this morning I could not watch tv without turning on the recorder. When i switched on the tv alone I got a no signal box on it yet when I turned on the recorder too the tv worked.As soon as I turn of the recorder I lose the tv signal again.This strange because I have not had this problem b4 since I bought the two items? Anyone who can help? thx
