Turned on my TV to find I have a menu but when I click on any channel there are several messages that appear: "Subscription Service", "Not Authorized". I already pay for these channels. I noticed last night that a few said not authorized but didn't pay attention as I thought there was a temporary glitch in your system. Also, sound has stopped working on my TV half way through playing DVDs for quite some time. Have blamed it on the DVDs but thinking this is box. I have tried unplugging and tightening all connections.
