Hi group,

My AIWA mini Hi Fi system model NSX SZ- 20(3cd changer,FM/SW/MW radio,
2deck)is giving problem suddenly.It is 3 yrs old.

Till the other day it plyed very well all my Imation audio CD R s
burnt with Nero ver 6.0 in Samsung cd writer.

Now when I put the same CD Rs the spindle tries to rotate the cd with
"CLICK" "CLICK" sound(atleast 3 times this sound comes and spindle
halts 3 times before picking up speed),finally the cd spins but no
track information or music and the system doesn't recognise the cd and
asks for a CD.

But Occassionally it plays the CDR.

If I use other audio CDs that came from recording companies,the
spindle has no problem spinning them without click click sound and any
halts in between.And the system plays these CDs well.So it seems my
system is apparently OK.


So where the problem is?
In the CDR s which were once plyed well and now occassionally played
too?Or in the Spindle? Do I have to clean up the Lens etc?


Any help is highly appreciated

Needs cleaning. Not a cleaning disc - a "real" cleaning.

Should help for a while, these units are dust magnets.

Take the top off the stereo and clean the CD lense with a slightly damp
with windex ( do NOT use alcohal ) coton swab then buff the lense with
the dry end of the swab .

whay can't you use alcohol?

On some lens units, but not all, the alcohol may cloud the lens. You can use
just a little dampening of water. Do not get any water or any kind of liquid
on the electronics.

In my 35 years of electronic servicing i have found alcohol a poor
choice of cleaner and useless .Use windex to clean lenses .

Thank you Jerry.
Yes ,alcohol generally clouds the lens rendering it useless.

Hi Mark,

Thanks for the advice.
Yesterday evening my system played all the CDRs it refused to play in
the morning.But today morning it again refused to play them.
I think the relatively low night temperature(around 26 C)is affeting
my system strangely after so many years of music.Cant believe it.
It seems it is a humidity problem.
Anyway I want to clean up the Lens.

In this AIWA NSX SZ-20 model how to access the lens?
Can I clean the lens with Tape Head cleaner solution?\

Thanks in advance
Swanky

Not familiar with this exact model. The lens is cleaned using a cotton swab
moistened but not dripping with window cleaner or Everclear-grade alcohol.
Clean the lens GENTLY with a circular rolling motion, follow immediately
with a dry one to get any residue. There's other maintenance type issues on
CD players but your immediate problem seems to involve only the laser lens.

You should be able to find the laser lens with a visual inspection. It's
very near the little disc turntable. A few Aiwa models do rather bury the
whole CD ass'y under a bunch of stuff at the bottom of the unit. Most mount
the cd section up high - it is this type that you can probably clean
yourself. If the CD section is down low, probably best get it to a shop.


Mark Z.

Thank you again Mark.

Presently my system doesnt have severe problems though I never cleaned
any inside part of it in the past three years.

It has this occassional difficulty (since the past few days)in reading
the track info from my Imation CDR s.When it does read
occassionally,some type of "scratching sound" comes initially while
reading the track info.Then ofcorse,it plays very well.This has been
happening for the past 3/4 days.It has no problem reading audio cds
from audio companies.

The cd assembly in my unit is on the top only.Will try to clean it up.
Just afraid that I might cause more damage and render it completely
useles.

Here I found people suggesting "WINDEX" ,window cleaner (what is this
anyway?)
isopryl alchol or Evercleargrade alcohol.I really dont have any idea
as to which one to choose.Ultimately it depends on which one is
available in my locality.


Thanks and regards
Swanky.

I think I'd just stick with any "blue" window cleaner. High-grade alcohol is
often used by engineers on expensive equipment, but if there's any chance of
clouding or fogging the plastic lens, why take that chance?
