If the fuse is not located on the back of the amplifier near the power cord, it is likely located inside on the circuit board. If you are not familiar with repairing electronic devices, DO NOT OPEN THE AMPLIFIER. There are dangerous voltages present inside the amp, even when the power cord is unplugged. Contact the store where you purchased the amplifier to recommend a repair depot.
Check the fuse in your furnace to see if it has blown.
If your speakers do not have an amplifier (excluding the subwoofer, which almost always has one), you will need a surround amplifier to power them. The DVD player connects to this receiver.
To safely perform a home fuse replacement, follow these steps: Turn off the main power switch to cut off electricity to the fuse box. Use a flashlight to locate the blown fuse. Use a fuse puller or insulated pliers to remove the blown fuse. Replace the blown fuse with a new one of the same amperage rating. Turn the main power switch back on and test the new fuse to ensure it is working properly.
You need a 5.1 Decoder and an amplifier to drive the speakers, most companies build these items into their RECEIVERS which comes with the switching you heed with most home theater systems.

The most common cause is bad wiring. Check the connections or replace the speaker wiring. If that does not work, check which speaker has the problem and see if a cone is blown. To do this, place your ear near the cone and gently press it in (don't push to hard). If the cone is blown you will hear a raspy rubbing sound when the cone moves. Replace the cone or the speaker if it is blown. If this does not work, change your speaker connections around to see if it is the amplifier.
To change a fuse in a fuse box, first, locate the fuse box in your home. Turn off the main power switch to ensure safety. Identify the blown fuse by checking for a darkened or broken filament.
