I have speaker wires coming out of the back of my house for back yard listening. I bought the house last year. There are only two hookups left inside the house and neither seem to operate the speaker I have attached to the outdoor wire. How do I check to see if the outdoor wire is working...
I have a new onkyo tx-nr747 that I am trying to connect to my 5 year old LG tv. I have used an hdmi cable and a digital optical cable. Still says no input on my tv. I have turned off and on, unplugged all of that. Is tv too old? Should I return receiver?
