What does it mean when "PROTECTION" is flashing on my Toshiba HTIB?

9 times out of 10 when you see this message on a Sony or Toshiba home theater system it has to do with the wiring of the speakers. Somewhere in the system there are wires that are either:Wires are touching somewhere.Wires may be out of phase (meaning one end of the wire is correct, and the opposite end is opposite).Speaker's and Receiver's OHMs ratings don't match. Make sure you're speakers and receivers share the same ohm rating (look for an upside down horsehoe on the back of the speakers and receiver).You could have had your system wired backwards for a long time and may not have ever known it, the system has been receiving feedback from the speakers for a long time and finally has just given itself up.

Normally when this happens its a very costly repair (typically its the main amp that needs to be replaced).Try calling Toshiba directly and ask them about resetting the system, that's about all you can really do if it is still acting up after you check all the connections.
