Hi,

I have a carver DTL50 that isn't working properly. Went to the CD Player
repair site and read a whole lot of information. Still, I am a newbie so
please respond accordingly.

Problem
All electronic display functions are fine. Draw opens and closes fine. The
CD loads correctly. The disk spins, there is some noise, and then it grinds
to a halt. I press play, the disk spins okay, but eventually comes to a halt
and the spindle spins beneath the disk, sometimes catching and sometimes
not. I have the cover off at this point and watch this from above. Loading
and unloading are smooth as silk. My question is, should I look to dirty
optics, or mechanical problem. Seems if the laser and mirror were dirty it
might not be sending the right information about spinning the disk. Of
course the other side of that coin is, that the spindle may be faulty
(although there is no play side to side in the spindle. I haven't yet
checked the pickup to see if its falling back into place properly.) I'm a
newbie, and enjoy a challenge, but if this beyond me, then so be it.
I'd like to hear some opinions on this. The deck matches my Carver
components that were willed to me by my father, so there is some desire to
repair here.

Thanks
Steve

I have a bit of a problem when you get to the bit about the spindle spinning
under the disc, and sometimes catching, and sometimes not. The disc should
be firmly clamped to the turntable at all times, whether the spindle motor
is spinning or not. With the disc loaded, the turntable should never be free
to rotate independantly of the disc.

With the machine halted, confirm that the disc is flat on the turntable, and
fixed there by the disc clamp. If it's not, then there's your problem, and
it should be an easy mechanical problem to spot and fix. It's not uncommon
on virtually any CD player, for the turntable to move slightly down the
spindle motor shaft. This will then often prevent the disc clamp from firmly
clamping the disc to the turntable. The turntable height is fairly critical
( to within 0.5 mm MAX ), so don't be tempted to move the turntable unless
you're sure that it has moved. If you get to that point, come back again,
and I'll see if I can guide you as to how to get it right

my old Hitachi had a magnet that clamped the disc in place, the magnet
came loose and got stuck right on the spindle instead of in the clamp
where it belonged.

Hi
Okay, I inserted the disc and it loads properly. Meaning the carriage takes
the disc inside the machine and clamps it to the turntable. At this point, I
am able to rotate the disc with my finger, in either direction. Meaning I
can spin the disc freely, but does not have play up and down. I press play
and the disc spins, there is a noise like loose stones rolling around inside
the deck, the disc slows, slips a great a deal, then it comes to a halt. I
advance the track to 2, and the disc spins much faster, then the same
rolling stones noise, the disc stops playing and then slowly comes to a
halt, like what you would expect if you had pressed the stop button.

I hope this is clear, I am a newbie, you know.

Thanks
Steve

At the very least a proper lens cleaning is in order. Other maintenance as
well, including cleaning any debris from around the spindle motor shaft and
applying a bit of light oil there (clean away any excess). Other moving
parts, slider surfaces etc should be cleaned and re-lubed as necessary.
Routine maintenance such as this has fixed many a cd player, and is worth at
least trying before looking for any more exotic problems.

Hi Again,

Thanks for the good advice.

What is anyone's reccomendation for the type of lubricants I should use on
the mechanical parts. For cleaning the lens I am going to use just alcohol.

Thanks
Steve

A very light oil for the spindle motor, perhaps sewing machine oil, or I
like a commercial product called Tri-Flow. I also use it on the metal rails
on which the laser rides. It works much like WD-40 is supposed to work,
except it seems to last, whereas we all know WD doesn't. It's silicon-based.
A fine litium grease is good for plastic gears.
