MD: AIWA Troubles =(

2000-05-01 Thread Richard


Hello,

This is my first post to the list I hope someone can help because this may
be too expensive to fix.  Here's the situation: said player was dropped onto a
lino floor. 
but stupidity of said action aside, :) the unit still plays well and seems to
work like a charm.. that is until you shake it. The model number is (AIWA
AM-F70 Portable Minidisc recorder and it is a japanese model). I have tried the
obvious, pulling the battery contacts out lightly, swabbing the contacts with
alcohol using a cleaner on the mechanism and it has not put me any further
ahead.  The problem SEEMS to be with the battery but doesnt have he same
problem consistantly enough. Like I say, the player plays fine but when it is
shaken (usually laterally) it turns off completely and / or intermittantly
powers on. There are no loose parts (audible anyway) in the main casing.
backlighting, display, playback and record funtions work normally until jarred.
it seems hopeless but Im assuming this is a large list and perhaps somone has
had a similar .. errr... stupid mistake :) Id love to hear about it.. this
thing isn't under warranty and I have a pretty good understanding of
electronics.  Any comments will be VERY much appreciated. Comments such as "I
dont know" arent worth posting :))) 

Thanks in advance,

-Richard

 Once the battery contacts are no longer in their original state, they may or
 may not maintain shape properly, no matter how you bend them.

Oh.. shoot.. I've noticed that minidisc recorders tend to be fiddly in this
respect.. a few Sony MZ R55's at work had these problems right out of the box
(fortunately we can return them to the vendors :) ). Okay,  well I'll try
getting come card behind the contact.. its better than paying $100 to get it
fixed. They really should make more surface area touch the batteries on these
things.. they just seem so flimsy. 

Regards, 

-Richard

Here is the proper way to fix it when  something breaks loose.

http://albums.photopoint.com/j/AlbumIndex?u=89237a=5557683  it does
take a bit f guts to do it though, and if you don't know what you are
doing, you can end up with a nice paper weight.

 My experience (with a couple cassette walkmans that use gumpacks) is that
 you can always try to do a temporary fix, but to be completely trouble free,
 you may have to seek the original company's service.
 
 I've tried stuffing paper beneath the contacts (not the lid, the one inside
 the unit), but how much paper to use seemd to be a delicate balancing act.
 Too much paper gets it too tight; too little paper doesn't do the job.
 
 My Kenwood K5 was only dropped a very long time ago, but starting last month
 it sometimes turned off by itself, just from being shaken in my pocket while
 I walked. I still have no good solution for that. Temporary solution has
 been holding it in my hands.
