There is either a shorted part in the power supply section or a shorted part (say a transistor if it uses them) in the main amp section. This will be located on the big heat sink. Power supply culprits are transformer, any semiconductor device, such as power regulator, rectifier etc.

Most of the time a shutdown is a protection circuit caused by a shorted speaker. Unplug speakers and see if it will turn back on, then hook up one at a time and power up to find if one has a short.

What is the source of your sound? By default, receiver will use only those channels that are used in the input signal - if you play CD in stereto, it will use only 2 front speakers. If you play DVD with 5.1 audio, it will use all 5 speakers (+ subwoofer if you have one).

However you can use one of the bulitin "sound field program" modes to mix the 2 channel stereo music to all speakers. On front panel, press "PROGRAM < >" buttons to select the one you like. Or on remote control, repeately press MOVIE, MUSIC or STEREO buttons. You can check your manual for description of each sound field program.
