Right speaker doesn t work - Lenovo Computers & Internet

It might have been disconnected from the board or the driver has not been installed.

Swap wires between speakers and to make sure it is not the amp, the head unit or wiring. If the right speaker still doesn't work touch a 9v battery to the speaker terminals for a second to verify if the speaker is good or bad (a pop the speaker is working nothing the speaker is bad)replace. Otherwise check the wiring between the amp and the head unit. If all the wiring is good you may have a bad channel in your amp(bad internal connection or bad component(s)) or last there could be a bad channel output on your head unit. If that is your only right speaker and you don't have one in the door and you use an ipod as a source check the cord!

try swapping the speakers around if the problem still persists either the speaker is faulty
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

Sir the problem of your unit is the power IC the other channel of this IC is already faulty. unplug the unit to the main AC outlet then remove the cover of your unit you will see a large aluminum plate the power IC is attach to that heat sink in order to fix this you should replace the IC. Or can you give me the part number of the IC so I can determine the pin configuration. Good day and best regards.

First, you can try unplugging and replugging the speakers. If that doesn't work, right-click on the speaker icon in the taskbar (lower right-hand corner) and select "Playback Devices". When the window opens, you should see your internal and external speakers listed. (Maybe Internal Speakers and "Headphones") Just right-click the option that says corresponds to your speakers and select "Set as Default Device". Close your web browser and re-open it. This should fix the problem.

take one of the front speakers out and pull out the head unit and unplug a set of audio wires(front right, front left ect.) and hook it up directly from the radio to the speaker there for bypassing all the cars wires. If it works then there's a problem with the car's wiring(maybe an inline amp). If it doesn't work, then try a known good speaker from somewhere else(home stereo speaker for example) and connect it to the radio, if the speaker works, your radio is fine and there may be a problem with the speakers. If it doesn't work then you have a problem with the head unit.

If one speaker doesn't work, then I would check the audio with another set of speakers. It could also be the sound balance that is turned all the way to the right. You can change the volume and balance in the control panel and sounds icon.

Make sure all the cables are connected properly.

Treble must be at mid-setting.

Make sure that the correct playback device is set as default in sound properties.
If all is well there then you could try a pair of headphones to see if the sound is working.
If headphones work ok then it is down to your built in speakers, not much you can do unfortunatly unless you are still under warentee
