Re: NSX-S555

tks again but i will have to check the voltages you mention when Play
button is pressed however if youhave the schematic for this part i
would thank if you send to my mail
mloo1955@xxxxxxxxx
I will let you know any advance

Just i cleaned the laser reader and now the Cd i working fine. I noted
with the deck that 2 belts,the biggest ones, are completey losse but I
think of that when I press Play the motor must try to move but I can
not see it. Please another suggestion and thanks for your help.

The motor should attempt to run when play is pressed, regardless of whether
or not the belts are in good condition, or correctly in place. If the motor
definitely doesn't run, first make sure that the front bearing hasn't seized
( they do ) or that it is not impeded in any way - such as a perished belt
having jumped off, and wrapped itself arount the motor shaft, behind the
pulley. This sometimes happens if a unit has been out of use for a long
time. The belts go sticky and spongy, and snag as soon as the motor runs. If
the motor is free to turn, but doesn't when you press play, you must check
that voltage appears across the two motor terminals marked " + " and " - ".
Ignore the two marked " A " and " B ". Expected voltage will be 12v. If no
voltage appears, then you may have a switching problem, a drive problem (
driver / switching transistor ) or a power supply issue ( open circuit
safety resistor perhaps ).

I think I've got a manual somewhere for an NSX - S555 ( Aiwa - right ?? ).
Repost if you're still in trouble with it, and I'll have a look, and see how
the motor is driven. There are several different deck assemblies fitted to
Aiwa models, but without doubt, the most common problem is bad belts. The
usual symptom is that the deck is jammed, the door latch release is blocked
( never force the door open in this condition - it breaks the latch pin )
and when you power up, the deck just goes click - click - click a few times
before going inert.
