You've got problems in the logic portion. If it were a laser problem the
disc would rotate and the sled would slide the laser block in and out
looking for a disc ID. A logic failure might mean a total failure of
this initialization procedure. There may be a small switch or optical
sensor telling the logic control that there are discs loaded. I think I
would start there given the symptoms.

If you read the previous posts, you'll see it is NOT a computer and
the
discs are NOT CD-Rs.

Often not the case, Meat. Many players will not start to spin the disc up or
move the laser down its slides, unless focus lock is obtained, The movement
of about an inch is often an attempt to move the disc to a different spot to
retry the initial focusing operation, in case the original spot on the disc
was dirty or damaged. This small movement of the disc may be carried out
just the once, or several times before it gives up and declares there to be
no disc ...

Just as a matter of interest, why has the OP started a new thread, instead
of continuing with his original, also called "Compact disc doesn't spin"
started two days ago ?

Beg ya pardon. Actually called "Disc tray won't open"

The original problem was the disc tray wouldn't open.

After that posting, I removed the top of the unit and discovered that
4 discs had been inserted (instead of only 3). By removing the extra
disc, the disc tray then would open..

Since the original problem had been solved, I started a new thread
describing the new problem: the compact disc wouldn't spin.

Getting back to this project.....while it works, I'm not happy with
the video quality with the simple RGB amp I threw together. Seems like
theres excessive contrast....backgrounds are too dark and small
details are getting buried. So I have an LM1203 I think will do a
better job.

I think the circuit in the app notes of the datasheet (p16) will
suffice. I'm foggy on what to do with the clamp gate input. They show
a sync stripper chip providing its signal, but I'm not working with
composite sync.....its seperate H/V passively mixed to "fake"
composite. The tv doesn't have a problem with it, but that chip might.

Any insight?

I wouldn't worry yourself about "slipping drive trains". It is *very*
unlikely that there is anything wrong with the disc positioning and
clamping. You can check for certain by spinning the disc with a finger after
it has stopped trying to spin it up. You will soon feel if the disc is not
firmly clamped to the turntable. The symptoms you are describing are
absolutely classic for a dirty or defective laser. Since you say that you
have cleaned the laser - I'm assuming of course that you know how to do this
properly - and it hasn't improved the situation, then that leaves a faulty
or worn out laser as the most likely bet.

There are other things that it can be, such as a defective connection
between the optical block and the servo board, or a fault in the servo
circuit itself. It could also be down to a defective spindle motor. They do
give trouble in most makes and models. You can often prove that by giving
the disc a 'flick' in the normal direction of rotation with a fingertip,
during that short period when it is trying to spin the disc up. Often, a bad
motor will 'take off' if helped like this, and will at least spin the disc
up to the point where the TOC can be read. It probably won't then go on to
actually play the disc, though.

site at http://profiles.yahoo.com/lady_veteran . It was taken down after a
dentist was shocked by the color of her teeth (Message-ID:
<43ms20p62nc280ro3q88en4h3vugdafg3l@4ax.com> ). LV subsequently replaced
the picture to avoid further embarrassment.

Like a wrestler, according to LV herself.

Message-ID: <ubfbqs4r0koopeg7fa86or27b9mpcmf2db@4ax.com>

10. Is Lady Veteran a lesbian?

Apart from her unfeminine looks and Usenet behavior, LV admits to wearing
men's pants ( Message-ID:
<0spvlskkdg305qpeibhltspl04qv12ipsu@4ax.com>#1/1).

11. Does Lady Veteran have her own newsgroups?

Yes.

alt.blobbi.veteran-cunt
alt.fan.boar-semen.blobbi-sanchez
alt.fan.boar-semen.blobbi-sanchez.aka
alt.fan.boar-semen.blobbi-sanchez.aka.aka.lady-veteran

12. Does Lady Veteran really live in a cheap, extended stay motel?

Yes. Note her personal profile posted at
http://www.bestjobsus.com/bt-empd-armyvet.htm . This address is for the
Budget Suites of America.

13. Does Lady Veteran take things to real life with people who disagree
with her?

Yes. As financially distressed as she is, LV paid a private investigator
$500 to track down a 20 year old Canadian named Marty who was besting her
with their every encounter. LV later took things to real life with Jim
Dutton and contacted his employer. LV's mission is to take things to real
life with anyone who disagrees with her, assuming she can track the person
down.

14. Was Lady Veteran turned down recently to foster chihauhaus?

Yes, because her home was not a suitable environment according to the
rescue organization.

15. Is Lady Veteran so broke that she could not fix her computer for over 3
months when it crashed?

Yes. Message-ID: <010d01c265d6$9467ea00$18ea3040@MAIN>

16. Is Lady Veteran really diseased?

Yes. She suffers from lupus and boils. LV probably has some
co-morbidities associated with obesity as well.

17. Why was Lady Veteran kicked out of the Army?

Speculation surrounds her lesbianism.

18. Is Lady Veteran a racist?

Yes. Quoting from Message-ID: <svebc0h9nbj6955bsurqic2bhck2e05t4i@4ax.com>

19. What does Lady Veteran think of Air Force pilots?

Lady Veteran is on the record stating that Air Force pilots are cowards.
Quoting from Message-ID:
<FD61BA67148006B8.0AC8A33AD0FC8798.555ED8B384D327D 0@lp.airnews.net>

They are most definitely cowards if they can't call a person fat to
their face and reap the benefits their comments so richly deserve.
BTW, I don't find hotshot pilots so brave. They fly up above the war
and could care less where their bombs fall. If they cared, maybe there
would be less war.

20. Is Lady Veteran, despite being a lesbian, homophobic?

Yes.

Quoting from Message-ID: <qu0571l8r39c8m1ib7a46dv63cai7hig6n@4ax.com>

Well when you get to the sigmoidoscopy just tell him that he is going

The idiots on this group sure can't say that.

21. Lady Veteran is a net loon. Is she also insane in real life?

Yes. In Lady Veteran's own words:

The actual problem was not an intermittent switch. It was the last thing I'd
have expected -- one of the welds on the battery pack had come loose!

Without turning this into a megillah... Any suggestions on repairing it
without damaging the cell? I don't have welding equipment. I do have an
EDSYN pencil iron, and a 100W RadioShack gun.

Please don't turn a straightforward question into a tsimmes. (But you will.)

The Edsyn will work. Didn't we just have a thread on soldering to
batteries? Maybe that was on a.h.r. Clean surfaces. Scuff with
sandpaper. Use liquid flux. Crank Edsyn up to 800F. Tin wire. Tin
battery. Use more flux and reflow wire to battery.

It happens. Spot welding takes practice.

Test the broken flat wire to see if it can be soldered. Keep the
battery as cold as possible (i.e. wet sponge). Plenty of liquid flux
and heat. Work fast to keep the heat affected zone to a minimum.

>Please don't turn a straightforward question into a tsimmes. (But you will.)

Mazel Tov. You can also build your own spot welder with a big fat
cazapitor. Search Google and YouTube for "capacitor discharge spot
welder". For example:
<http://forum.allaboutcircuits.com/showthread.php?t=24385>
If you don't want to build the entire circuit, just charge up the
biggest capacitor bank you can throw together. One lead goes to the
battery terminal. The flat wire goes is placed on top of the
terminal. The electrode is some kind of heavy (#10 awg) solid copper
wire. Compress this sandwich together, and apply power at the
capacitor bank. Hopefully, it will weld the flat wire, and not the
capacitor terminals. In theory, the stainless leads with have a
higher resistance than the copper electrodes, so the stainless will
heat up, not the copper.

Last resort is to drag it down to Batteries Plus or some similar
vendor that has the proper spot welder.

Very last resort is to just slop some epoxy on the flat wire and
battery terminal, and hope that it holds.

There is a conductive epoxy that can be used to fix this sort of thing...

Wouldn't that be nice? Those schematics painted on rice grains
pasted on the insides of old Japanese radios actually were
readable when scanned and resized to a practical size. Too
bad that mfg'ers don't do that any more for the most part.

There is nothing at all on the inside of the cover or on the
chassis...

They don't print schematics for microwaves. It's because most users
don't want them repaired and if you don't know how a microwave works,
then you have no business being inside of one.

Well, I would use Google to download a schematic, there's a start.

Have you ever used an optical mouse? Ever notice how the LED gets
brighter when you move the mouse? It sounds like what you want to do is
dangerous. If you have the LED on at full brightness all the time, then
it will overheat and catch the mouse on fire.
