I have an LG fb163 everything seems to function but no sound in the speakers

check mute button, source knob/button, speaker selection knob/button while its playing a cd or FM radio. Also if you have connected headphones the speakers would mute. Check the speaker connections. If the speakers are powered you need to connect them to a power source. If all these fail to produce sound consult a technician.

This sounds like an internal amplifier problem. Did you smell anything burn? Try turning it off completely and plugging it to a different outlet.

If all else fails, have it checked by an electronics technician...

The speaker make a buzzing sound

that's called breaking up or overloading it means that the speaker is being asked to play louder than it was designed to play!! this will ruin the speaker at all volume levels if allowed to make that sound for very long..advice? lower the volume till that noise disappears it's not a product fault it's user error advice turn it down or buy a more powerful unit to achieve the volume you want/need

Right speaker terminal not working - tested out both speakers and they work fine when independently tested on the left speaker terminal. Sony MHC GX45 Shelf System, 2 speakers and 1 sub.

If the sound is also dead on that channel on a pair of headphones. Then you have probably lost the main power amp for that channel. To be certain. With you headphones on, slide or turn the balance control so you can only hear the faulty channel. With some music playing turn up the volume. If you can hear "faintly" music playing then the pre-amp is OK and the power amp has gone.
The power amp will be located on a heat sink. It will consist of 4 transistors (2 for each channel) or one big device (or two) (an IC). If it is transistors you only need to replace the two for the right channel.

No sound opened component two blown fuses

Fuses blow when there's an overload. This is often caused by faulty speaker wiring. But the main problem you have will be that the main power amp will have failed. You will find this on a big heat sink. It could be transistors, or a power amp IC, picture below of what that could look like.

You should be aware of the power output of the shelf system and at what ohms. Ex.--100watts @ 8 ohms. Which I think that is the rating of this unit. This means you will get 100 watts of power on the front left side and the front right side, if you hook up one 8 ohm speaker per side.

No sound whatever

when you switch the unit on make sure that you hear two clicks, this will tell you whether the protection relay is working. Should you hear the two clicks this will indicate that the audio ic`s are working. There are fuses inside the main component box, four on the transformer. Let me know the outcome

Check the speakers connections. The speaker cables may be shorted. Turn the unit off, check and correct the connections and turn the unit on. good luck :-)
