Dear DJ,

I received a whole shipment of new stylus that were broken.  They were a free
gift
sent by a nice gentlemen in Pennsylvania.

It took several tries, but I took four broken cartridges and from these I
reconstructed one working cartridge.  If the ribbon is connected to the stylus,
you can solder the ribbon back to the cartridge using surgical tweezers to hold
things in place.  A minimum of solder is best.  There are several problems
attempting this.  First, it is difficult to get everything in place and set up
with the proper bend to the ribbon while it sits in place for solder.  Second,
the
copper hold on the cartridge or copper button where the ribbon attaches to the
cartridge can become heated to the point where it pushes through the cartridge.
Once that button goes through because of heat you have to begin again on a new
cartridge main body.

So, for best results do it quickly with a minimum of solder to hold the ribbon
to
the copper button on the cartridge

Tom,

My condolences on your cat.

The other person who wrote about the disc problem, sounds like they were
putting
in side two of disc two where no program material exists.

Hello!  Firstly, what a great site...an excellent resource.  I inherited a RCA
SelctaVision disc player and > 20 discs from a relative who told me it was a
Laserdisc player.  The darn player wouldn't work.  I started to list some of
the discs on Ebay.  Come to find out, a kind Ebay-er told me that I was
incorrectly listing these as LDs when in fact they are CEDs.  Ignorance is
bliss! 
 
Anyhow, now that I know what I have, I want to fix this thing.  The discs load
just fine, however, the LCD panel just indicates 2 horizontal red lines once
the disc is loaded.  I took it apart and the motor seems to work however I
suspect a belt is out.  Radio Shack told me to get lost.  I looked into your
site a little and can't quite determine whether I need the Servo Drive Belt,
Turntable Drive Belt, or the Function Motor Drive Belt.  Your pictures are
highly detailed, yet I still don't know which one to order. 
 
Any advice?  Again, thanks so much for your great site and interest in old
electronics.
Mark

Hi, everybody!

My fault!  I was not clear on the matter.  Before posting about a
problem, I tried every reasonable and logical approach to a solution
that came to mind.

I played both sides of the second disk with the same null results.

I removed the platter from the sleeve and inspected both surfaces; there
appear to be no scratches or other visible defects.

It worked fine once upon a time and disk two of this movie has data on
both sides.  The final 18 minutes is on side two of disk two.  That
means no matter which side I play, I should get something.  Odd that
both sides should prove faulty now when once upon a time they both
worked.  It has all the earmarks of a physical rather than a logical
problem, but I have no idea what it might be.  The damage could be
microscopic, I suppose, but other than a scratch or imbedded particle, I
have no idea what to look for.  Is the data binary - as in '0's and
'1's? - so that the destruction of a single bit would impair the entire
'start-up' sequence?  That's what happens with a hard drive when you
blow out the FAT data in Sector '0' ...

Subject: SGT100 woes...
To: "'digest@cedmagic.com'" <digest@cedmagic.com>

Greetings.  I'm new to the CED scene, having been given a non-functioning
SGT100 and several disks. To eliminate the possibility, I bit the bullet and
replaced the stylus with a NOS 154100.  $58.00 later, and still not working,
I'm a little dismayed, but nonetheless committed to fixing it.  I'll
describe exactly what it's doing (actually, not doing), along with what I've
checked, so that maybe you experts have a suggestion.

1) I get a flashing "L" in the load/unload position - seems normal.
2) After loading and moving the lever to play, the platter spins up, but I
get only "- -" on the display.  I never get a video or audio signal on the
screen.

3) Upon examination, the stylus does lower into position onto the disk, but
the servo drive never attempts to advance.  
4) If I move the arm off of the resting position, to somewhere nearer the
center of the player, and then turn it on, the servo WILL move the arm
backward toward to rear of the player a couple centimeters before lowering
the stylus, but still no signal of any type.

5) I have checked the regulator voltages at the test points indicated in the
"FAQ" section of the website - all are right on target.

Ideas?

CED titles do vary in a measurement called "the diameter of the first modulated
groove." If this disc happens to have a small value for this measurement
relative to other discs in your collection, it could result in no playback on
that disc, while other discs play OK. A quick check would be to turn the SGT075
player off and advance the pickup arm by hand to the approximate middle of the
groove band. If playback then occurs when the power is switched back on, an
adjustment of the stylus set down position may be in order:

P.S. Thanks to all the cat and dog lovers for the condolence messages on the
passing of Astarte.
