DESKTOP PC AUDIO OUT NOT WORKING REPAIR GUIDE
Today I got a new challenge from a customer. His desktop PC will not play any sound anymore. After I try to connect my headphone jack to the audio out port on the PC it wont go enough deep into the hole, just half a way. Hmmm this is strange. I inspected the inlet of the hole with a lamp and I saw something was stuck but too deep. I tried to reach the jammed part with different tools but no chance to come close to it and get it out. Therefore, I decide to change the audio connector.
I took out the motherboard from the PC case and lift out the RAM and the CPU. The reason why I took out the CPU and RAM is that the possibility of electrostatic discharge until I work around the motherboard is high.
Whenever you do some job like soldering on the motherboard, take care of other parts on the board and avoid getting electrostatic discharge. On the motherboard are very sensitive parts, if electrostatic discharge comes across the board they could be damaged.
I done the desoldering with my ZD-915 desoldering station. My best advices to you, if you have no desoldering station then do not try to take the audio connector from the board because, probably you will destroy the board. It must not be but, from my experience, this connector as other too, can’t be removed with a classic soldering iron and a mechanical vacuum pump.
Now, when I removed the soldering lead from the legs of the connector I took a screwdriver, carefully – gently pushed under the connector, and pushed the connector up.
Be carefully how deep you go under the connector with your tool, because around the connector are small components and there are wiring too. If you go too deep with your tool then you can destroy the wirings or around the small resistors, capacitors…
Take care with the soldering temperature too. I used 480 Celcius for desoldering and for soldering is 330C but very short time. Otherwise, you can burn the board, solder bad connection or overheat the board and in most case, the circuit layers will separate. I got another audio connector from an old used motherboard and replaced the defective connector with the used one.
After repairing I turn on the PC and made some nice noise. I mean, got a cup of coffee and listened some good music from YouTube. I hope this article will save lot motherboards from junkyards.
