Question about Dell INSPIRON 6000 CENTRINO 1.7GHZ,512mb,40GB,DVDRW,XP (086216118098) PC Notebook
There is no sound coming from the speakers although when headphones are connected, there is sound but only on the left channel. Could it be a problem with the change-over connections in the head set connection unit?
There is no sound even when the computor is starting up.
Any advice please.
Since you can hear something using the headphone on the left side, then we can rule out that the driver and/or the sound device of the laptop is defective.
1. The headset right side is defective or the wiring or the solder joint to the TRS connector;
2. As you posted the change-over internal to the laptop is defective or has some corrosion, dirt or foreign material that obstruct positive contact/connection;
3. In some instances, it has been determined that the soldered joints of the change-over develops cold solder or simply looses contact to the PCB;
4. It is also possible a combination of the above.
Corrective measure(s) would entail:
a. Use a continuity tester at the TRS connector to determine if both the left and right of the headset works. Alternately, an ordinary AA battery can be used. There should be a clicking sound when low power is applied to the contacts. If none, the wire form the TRS connector to the left and right mini speakers should be checked. The speakers themselves can be checked and should show anywhere from 4 ~ 16 ohms.
b. A possible temporary workaround on the dirty change-over is to spray it with electronic contact cleaner and thereafter with a can of compressed air.
c. If it is a cold solder problem, wiggling the TRS connector while plugged to the jack would at times make the sound appear on the headset. True repair of course would involve opening the laptop and resoldering or replacing the change-over component. This could also very well be the reason there is no sound in the internal speaker.
Option c would require that you be familiar with electronic components and circuitry, use of a DVM and a soldering iron and would be able to open the bottom cover of the laptop. If you are uncomfortable doing this, perhaps your best bet would be to seek the services of a qualified professional.
Hope that this be of some help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
