Having problems with your PC Desktops ?

No sound from altec lansing speakers, but have plenty of sound from headphones Not sure what speakers I have but they're around five years old. Also have subwoofer; could that be the problem? Hope someone can help! Ted


Answers :

Without a model number of your speakers, this is going to be\015\012kind of generic.

\015\012\015\012There are 2 major causes. 1) Damaged wire or 2) Bad wall\015\012Power supply or 3) Bad internal Power supply

\015\012\015\0121) When you turn on the speakers are there any lights? If\015\012you normally have lights and there aren’t any go to 2) below. If the lights are\015\012on then the likeliest problem would be the damage to the cord that plugs into\015\012the computer. The damage could be as obvious as frayed wires (like a pet was\015\012chewing on them) or a crease in it (like if it got pinched in a door or under a\015\012piece of furniture) or if the wire was stretched. Stretched wire is the hardest\015\012to detect. You need to examine the entire length of the wire both visually and\015\012by feel for any area that is different than the rest of the wire. If there is damage\015\012the cord it can be repaired. The instructions can get complicated so if you\015\012find damage write me back and I will talk you through it.
\015\012\015\012
\015\012\015\0122) Having a Subwoofer I assume that it must have a power\015\012supply. If the power supply is the type of “Brick” the plugs directly into the\015\012wall, you need to make sure that the wire coming out of the brick is securely plugged\015\012into the speaker. If you have a volt meter you can verify that the voltage is\015\012close to what is to what is written on the power supply (within a volt or so).\015\012If the voltage is too low replace it. If it’s a couple of volts high it’s fine.
\015\012\015\012
\015\012\015\0123) If there is no brick connected to the wall outlet, then\015\012there’s a power cord likely it’s running directly into the subwoofer. That\015\012would indicate that the power supply is internal to the subwoofer. Check the\015\012area where the power cord enters the subwoofer for a fuse. If you find one you\015\012can check it with an ohm meter or some hardware stores will check them for you\015\012too, which is convenient, because you can pick up a replacement there too. If\015\012you cannot find a fuse (accessible from the outside) there still might be a\015\012fuse internally. BE SURE THE PLUG IS PULLED FROM THE WALL OUTLET! Then see if you\015\012can figure out how to open the case. There are different types of fuses, but the\015\012fuse will likely look like a small glass tube. If the fuse is not the problem,\015\012power supplies can be repaired (or replaced) but, not without some electronics\015\012training. Also the cost of having a repair shop would be cost prohibitive.

Best of luck to you!
