| 285.10 | Car stereo problem | TRUCKS::BEATON_S | I Just Look Innocent | Fri Jan 22 1993 15:29 | 36 |
| This looks like a good place....
I have a problem with my car radio.
I have a 4 speaker system and basically the front rhs speaker 'cuts
out' every now and again.
At first I thought it must either be a duff speaker; change speaker;
same symptoms persist.
Next I think 'duff connection; Checked this out by transferring the RH
speaker cable to feed into the LH speaker; the problem remained on the
RH speaker.
I've been putting up with this for some time now as quite often sound
will come out of the front RH speaker without any problem.
The other day I noticed the following when the front RH speaker was
playing up. The volume control, when pressed, also acts as the L-R
balance control. On this occasion when I pressed the volume control
(but did not turn it) the front RH speaker came to life; release the
volume control and the front RH speaker fades out ! I was able to
repeat this exercise to my heart's content.
It's as if the balance control has developed a mind of its own !
Now the question is (for all you radio experts out there) does this
sound like "buy a new stereo" time or is there a simple fix for this ?
(Appart from holding the volume button down all the time.)
Any advice/help appreciated.
Reargards,
Stephen

| re .10
It is fairly common for volume controls and the like to go wrong. The
part should be replaceable, but it is not likely to be a standard part.
You would probably have to go to the manufacturer for a spare, or take
the radio to a specialist repair shop.

| In PRC we used to use stuff called AF-Spray to clean flux etc off
boards....it turned out this was great stuff for getting gunge out
of the tracks of carbon potentiometers....I think it was Freon
based so fixing your radio won't be environmentally friendly. If
it's easy to remove and take apart, try spraying Isopropyl alcohol
(or maybe meths) into the Volume put. If it doesn't fix it, drink
the remains and forget the problem!!

| Stephen,
Yeah it sounds like you need a little squirt of contact cleaner in there.
It leaves a conductive layer on the newly cleaned surface.
I just happen to have some in the boot of my car if you are ever in the DEC
Park area.
I would be careful with this, don't apply too much or miss the surface of
the potentiometer behind the balance knob.
Regards,
Robert Screene.
