RCA Home Theatre died

  1. I have an RCA Home Theatre System RT2380BK that will not turn on anymore.
    When I plug it in, the red standby light comes on. When I press the power
    button, I hear the relay click on and the standby light goes out, but it
    never says "Wecome" which is what it is supposed to do next. If I
    disconnect the power supply from the rest of the circuit, it does the same
    thing, but if I disconnect one of the display/control panel cables from a
    main board, the relay doesn't click and the standby light doesn't go out.
    (There are only 2 cables going from the display/control panel; the other one
    goes to the on/off switch). I even removed the fuse from the power supply
    and it did the same thing, but the fuse is good. Any ideas?

    First thing i would do is locate the memory backup battery ( if it has
    one ) usually found on the front board ( sometimes elsewhere ) It
    usually looks much like a big watch battery . With the unit unplugged
    from the power Take something and short across the battery for a few
    seconds ... other than that ??? audio amp shorted ???

    I have found several newer Pioneer receivers needing this treatment .
