Knackered Speaker Port!

Hi there,

I built my Shuttle SB61G2 Computer nearly two years ago and have had no
problem since.

Unfortunately the speaker input (green) port at the back of the PC
seems to have a loose connection, as only the right speaker will work
when it is fully plugged in. Although this is not always the case as
sometimes both speakers work.

Another theory was that the onboard sound was faulty, however the sound
port on the front of the computer works perfectly.

Can i ask is there a way of fixing this 'loose connection' without
replacing the entire motherboard?


Thanks for your time!

You HAVE checked the speakers on something else or tried a different
set of speakers?

Open the case and trace back from the jack. Try (carefully) to see if you
get a signal back between the jack and the first last component.

Yes, work out why you are getting intermittent contact with that connector.

It can be something as simple as the wiper in that connector having
got bent, or it can be a poor solder joint where the connector is soldered
onto the motherboard. It isnt hard to resolder it if thats the problem and
you can solder. It can also be a cracked trace but thats not hard to fix
if you know what you are doing. You can usually distinguish a cracked
trace from the other two by wriggling the jack in the connector with
sound playing and listen to the bad speaker. If it comes and goes by
wriggling, it wont usually be due to a cracked trace.

I've had this happen on several PC's - and it's not neccessarily down to
constant plugging/unplugging of the speakers, as it has happened on PC's
that I haven't touched for a while. Always the same symptom - wiggling the
speaker connector makes one of the channels come and go. I've always
believed it's caused by oxidisation of the (cheap) motherboard connectors. I
would try cleaning the speaker jack plug and lubing it with a little motor
car gear oil. You can get special lubricants for electronic connectors but
they tend to be pricey. Idea is the lube stops oxidisation and helps to
clean off what's already there.

Shouldnt be, they're always plated so oxidisation doesnt happen.

Thats the last thing you should do.

Usually called contact cleaner.

Nope.

Not with that type of connector. They are always plated
and dont carry any current so dont get oxidised.

gear oil will just attract dust and make the problem much worse.
