The other day i accidentally crossed a couple of speaker wires on the back of my MHC-MG510 AV. The sound faded in the system and blew the 3.15A 120V fuse by the plug. I took it apart and replaced the fuse with no luck, blew 3 fuses that way. The speakers are disconnected from the system and the only thing that seems to work after the fuse blows is the red light on the power button. What could be the problem? Please help, thank you.
Fuses blow when there is an overload. In your case when you crossed the speaker wires you shorted the main amp. This now has a part that is acting just like a strand of wire.
Trace back the channel you crossed the wires and find the main output device(s). Then replace them. They will be located on a heat sink if that helps.

Hi Guys
Johnac is right the same amplifier that produces sound on the head phones drives the speaker outputs. If you plug in the headphones you will have no sound form the speakers.
If there was a problem with either a fuse or a sound output device you would have the set not switching on as Sony has buildt a very comprehensive protection system into the GX880.
My suggestion is to also check your spekaer wiring. Or the speakers them selves might be faulty.
Also make sure you have set the soundfield setting to Dolby Pro-logic too enable all the speakers to have sound on playback. Thereby chacking too see if it is not only your front speakers that is faulty.
Best of luck

hello my frien let me tell you that the system wont accept more speakers or diferent loads per ohm if the total load says 16 ohms by channel thats the total can handle so if you ad more speakers the system turns off before it burns or or have a severe damage........saludos

If you have an output function at the back of your mini HIFI then surely you can.What you need is a Dual RCA [from the mini HIFI] to 3.5 mm Stereo Jack [to the PC]. The cable is easily available in the market...go to this site n you'll get the idea http://www.vpi.us/cable-audio.html
