    My house was struck by lightning about a week ago. We lost cable TV and a cable modem along with a cordless phone. My entire home theater system checked out fine the next day, however...

    I now hear a very low (probably from the sub) single "thump" whenever I execute a command on the DVD player. It could be selecting something on the disc menu or even shuttling back and forth through the movie. It's not very loud but it is a minor annoyance.

    Other than that everything works tip top.

    Anybody have any idea what the issue might be?

    well for starters you need to isolate the problem..what happens when you disconnect the sub?

    Just tried it. When the sub is disconnected there is no occurance of said "thump".

    Well I had a similar problem except the noise came from
    the center and it was constant while subtitle or menu
    pages from DVD where shown.
    I suggest disconnecting the sub from the receiver pre out
    and leave the wire connected to the sub.
    Do the test again , pay attention carefully to the other speakers.
    If they acting normal pay attention to the disconnected sub.
    If the hum still there when the sub is disconnected the problem is not inside your receiver.
    If you can't hear the hum then the problem is probably inside your receiver.
    I had to change grounding connections inside my receiver
    (Onkyo 939 ) and it solved the problem.
