20 Most Recent Altec Lansing ACS 251 Computer Speakers Questions & Answers

Remove 8 screws, soak seam plastic with WD40 or lubricant. It takes some tapping work with a long flat metal along edges of seam all the way around. Have a schematic? Mice got into one I have and rusted away several small resistors on the ACS31 circuit board. I need an image of the values/schematic!

You can view the user manual online at: https://www.slideshare.net/JosephAbell5/boston-acoustics-ba735-user-manual-86903808 Hope this helps ..if someone still needs it. ;-) Let us know.

18 gauge wire will work in most speaker applications. To extend 6 feet, the gauge hardly matters at all. Do observe the wire colors and match them up on both ends of the cord you use as the extender. A cord w/o colors (like lamp cord) may have a ribbed side so you can tell which conductor is which. This isn't mission-critical, but the phasing of your speakers does matter a bit in the overall sound.

first remove the net from the sides.then just above the controls of the speaker.there is a super glued joint where the two colors are combines..gently open it by screwdriver.i have opened it.put the screwdriver between the colored joints and push it down gently.it will definitely work.

this is the question and answers:does your sound driver install properly?does your sound card config properly? if not you can config that in control panel and choose wether 5.1 soround or headset or desktop speaker

if youve checked the fuse and thats ok, its probably going to be cheaper to buy new than repair

Hi. You might want to try a different set of speakers or try the Altec Lansing on a different computer to isolate the issue. This can tell you if the problem is with the computer's sound card or your speakers. If the speakers won't work with any PC, try checking if the wires are all good and/ or soldered properly. Be cautious while doing this. make sure the speakers are not plugged in to any power source. I hope this helps. :-)

Hi

Good day. In regards to your issue your speaker connector might be grounded and there's no way to fix that i''m sorry. But try to do this step first to be sure

1.Make sure your speakers are plugged in, turned on, and properly connected to the
computer. You've probably checked this, but it's amazing how little problems like this (or the
computer's sound being muted) manage to confound people.

2. Plug the speakers in to another computer, if possible. If the speakers work with the other
computer, proceed to the next step. If they don't, you've probably got a problem within the
speakers themselves.

3. Check sound card driver
> Open your start menu (right-click on the "Start" button and choose "Explore"), and find the "My
Computer" icon. Right-click on it and choose "Properties" from the submenu. Click on the
"Hardware" tab and then the "Device Manager" button.
> Expand the "Sounds, video, and game controllers" heading to find your sound card. The name
will depend on what sound card is installed on your PC. It will most likely have a name
containing "audio." It should look something similar to the example above. You'll know
immediately if there is a major driver error because an exclamation point (!) will show over the
card's icon.
> Double-click on the name of the sound card to open a new window. In the new properties window
click on the "Drivers" tab. If there is no "Drivers" tab then you chose the wrong sound device. Go
back and try again. On the "Drivers" tab, click the "Driver Update" button. Follow the Wizard's
onscreen instructions to update your driver. You can also contact the manufacturer of your PC
for the most recent audio drivers. They can usually be found online.
> If you already have the most recent driver, click the "Uninstall Driver" button. Then restart your
computer. When you restart your computer, the driver should reinstall automatically. If it does
not, install it manually with software (or a download) from the manufacturer.

4. Check the "Windows Troubleshooter". On the "Drivers" tab mentioned in the step above,
there is a button for troubleshooting the device. Click on that button, and follow the instructions
on screen.

5. Check the sound card itself. Properly shut down your PC and then disconnect all cables on
the back of your PC, including the power cable. Open up the CPU, making sure to touch a
grounded metal object (a doorknob or metal desk will work, for example) before opening up the
case. This will discharge any static electricity you have built up, which could damage your
computer.
> Locate the audio plug on the back of your PC. The sound card should be in the corresponding
location on the inside of the PC. Remove the sound card and put it back in. The Microsoft site
has detailed directions for installing a sound card; to remove one, simply do the reverse. Once
you have the sound card back in, reattach the cables you unplugged earlier and boot your PC

It this steps didn't work you might consider getting a new one. Hope this help you in someway and thanks for visiting Fixya. Have a wonderful day.

Sounds like you lost your driver if you cleaned out your hard drive & didn't save a copy. Try going online & search for the driver & download it, I would save a copy, maybe on a disc or floppy.

the best is to go make sure not youre setting if not that then i would contact supliers

You won't fry anything. Just color match. You should be fine.
