Intermittent volume from speakers

[AZA]

I had some repair work done on my Toshiba WX-1 a while back.
One of the problems i had was that the left speakers would cut in
and out. At first i thought the light switch was somehow creating a
short because when i pushed it on or off i would sometimes get
some noise. Anyway i took it to a tech guy to fix, along with a few other
issues, and he said the problem was in the headphone socket.
Now, i have had this problem before and dont know why i didnt even think of it ?
Only problem is he said he couldnt fix it ?? He apparently tried and made it
slightly better but the problem is still there and the speakers cut out all
the time :'-(
Unfortunately im not a tech, not even close but i can cut a few wires !
So my question is this, if i disconnect the headphone socket completely
will this fix my problem ?? No headphones of course but i can live with that.
Any info or ideas would help greatly thankyou.

I've only encountered this same problem once. I followed somebody's advice of spraying DeOxit into the headphone jack (without the straw), and then working the jack with a headphone plug. Dang if it didn't fix it right up! Sometimes things can be that simple.

Give it a try and see how it works out for you.

If it's really the headphone socket and it's due to the contacts losing their tension or something, then you can probably just bypass it. The headphone socket acts like a switch.

man , id guess the RV's i mean the variable resistor

that controls the volume is glitchy...

somethimes deox as bdog said, or if it remains,

a new one.

but prolly cleaning will do it.

if its from the headphone jack, maybe its dirty and it connects from time to time

something so you loose audio, in that case, also cleaning will do the trick.

alas, if it doesnt , just disconect the wires going to the jack. and taping them for no shorts.

WAZAAAAAAAAAAAAAAAAAAAAAAAAAAA

headphone jack is probably just worn out, previous owner (unless it was always yours) may have used the head phones a lot, when the headphone plug is inserted into the jack it pushes on a metal tab which will cut off the main speakers,that metal tab may have lost it's "spring" and is moving too easily when it vibrates from the main speakers,possibly. At least if that was the problem, replacing the jack or bypassing it should have cured the problem, either one any tech would have been able to do so if your tech couldn't fix the problem, most likely it is something else.

i have a trc931 the had a headphone jack problem, intermittent sound. i just took it off (though it did require unsoldering it) disassembled it and cleaned all the corrosion of of it, reassembled and re-solder it back on and my problem was gone! sounds clean and loud like it should. I thought about bypassing but if it is the headphone jack, i would clean it.

Thanks for the reply guys. I did try cleaning the headphone plug but it is very persistant and continues to play-up.
If i try anymore spray i may flood the box !!
I think i will have to try removing the headphone connection altogether from inside.
Thanks again.
Now please see my next Tech Thread, Sanyo C20 :'-(

de-solder with lots of caution and label everything you remove

and make schematics so you dont forget...

tape and isolate what leads you leave unwired.

might solve it lets hope.

YO

gotta be very careful. i take pics so i know what goes where and how.

Definitely try the deoxit, 9 times out of 10 it will work. Headphone jacks do become tarnished over time. Do not bypass the headphone jack, unless you are able to bypass the circuit or you will lose sound completely. The headphone jack has contacts that when the headphones are inserted automatically shuts off the speakers. When you pull it out , the contacts again touch allowing sound to flow through. If you cut these, it is equivalent to having the headphones plugged in, or no sound from the speakers. :sin:

Post back and let us know how you did!

stynger is right --DONT cut the jack wires !!!
