How do you repair a speaker if it doesn’t work?
FIRST and foremost BE SURE it is plugged into the right port of your sound card on your computer. This is by far the biggest error I have seen. This located in in back of your computer and some now have them in the front also. It is normally a light green color. If your unsure try each one. You will need to reboot your computer each time if you want to hear the ever famous tone of windows. BUT! here is what I do. I find a CD with music on or load a song that is in the computer or internet. I use youtube.com quite a bit. While it is playing try each plug.
What else could it be?
Most speakers come with a power adapter. (Cheaper ones use batteries) Be sure it is plugged into a live outlet. If you use a surge protector be sure it is turned on. Another big one! Be sure the on button is pushed in or turned on and that the volume is turned up. It is really embarrassing if you pay a technician to turn a simple dial just to hear sound. Oh! did I mention that you need to pay technicians?
What if this doesn’t work?
Find the picture of a speaker in the lower right corner of you desktop. You may have to click the small left pointed arrow to see the entire area. Double click it. This should bring up “Volume Control” screen. Check to see that “Volume Control” is not muted and that the bar is up as far as it will go. Also check to be sure nothing else is muted.
OK! what if that doesn’t work?
There could be something wrong with your sound card or you don’t have the right driver loaded for the sound card. Many computers now come with the sound card integrated in the motherboard. This doesn’t matter. It either works or it doesn’t. They both will need driver software to work. Also be sure the software is for the proper operating system. Many time the problem occurs when you upgrade from one operating system to another. Windows 98 drivers very often do not work on VISTA as an example. Usually the driver can be downloaded from the manufacturers web site. If the sound card is integrated into the motherboard you need to go to either contact the manufacturer of the mother board or go to their web site. Some of them have online forms to fill out.
