Connect headphones to see if you're getting sound from the unit your connected to. If you get sound then the amp fuse might have blown out or IC is gone bad on the unit. If this is a laptop or desktop reboot the system and see if sound returns. Try updating your sound drivers for your PC.

My speakers ios properly connected to my wipro computer(HCM782M)but we don' hear any voice by speakers ...

Is the audio card or on board audio enabled? What about the sound properties? is the volume muted? Power supply for speakers working? Are the speakers working? Unplug the cable and touch the tip of the jack- you should hear noise when you make contact. The fast way to test them.

Panasonic sc-hc3db

I researched this problem for far too long and have learned the following: The UK version of the product has a fuse in the power cord plug end. The item has three typical problems: failure of IC chip, and/or one or two diodes. Unless you are good with a soldering pencil and have some skill, it's best to make a set of speakers from those on the unit and junk the rest of it. Otherwise, it's not worth repairing or salvaging. Remember the negative terminal on speakers made be shared and is the furtherest ring out when joining a stereo mini plug to two speakers. This brand of docks usually fails due to heat dissipation problems as there is no room inside them to keep things cool and Mashushita didn't put a fan in there.

Static but no music from the satelite trebble speaker

Try to reconnect all the wires, the problem seems to be with connection. Instead of spending lot of money on speakers, you can buy just the wires, they are pretty cheap. Hope this helps.

I played some high music and the left speaker stopped working but if i take of the grill and touch it, it work but when i take my volum up it stops again, z-230,

The speaker is usually a simple network consisting of a connection point and a crossover network and the speaker it self. all of thes components have connecting points. One of the three areas is having a problem. Check all these connections and see if the have developed a bad or cold solder joint. They also may have a broken connection. Usually a wire connector. You may be able to repair or replace it. If one the areas is damaged you may need to replace it.The components usually have part numbers on them. Use this part number in the search engines of the web to find a replacement part.If the expense is more than the speaker is worth, you may just want to replace the speaker. I hope this information helps you with your problem.

First things First!
1) check on other speakers to see if your iPod work fine

3) check with your headphones to see if your iPod play music well.
4) Check, power on the computer spk. you got. or the input that is working right.
