Are you just asking for the wire (cable?) Then it is indeed called
just ribbon cable, or flat ribbon cable. You need to specify the # of
conductors (looks like 28 or 30 in your photo) and the pitch.

Go to Digikey and search for ribbon cable....

If you just need a few inches, then you could probably make what you
need from some hard drive or floppy cables. If you need it with
particular connectors on the ends, then there are several varieties of
these available there, too. Most of them are insulation displacement
types which you can install yourself with the help of a vice.

To minimize contact with them I even quit using Paypal, as they wanted too

No, if you were him, he be kicked off Ebay for selling pictures of

Good luck; you'll need it.;

You see the letter from Ebay does not appear valid. ( The original

It does not seem like one of the in fights ongoing inside Ebay.

Easier than that, just moved the aerial to the other side of the bench as

Secreted some heated silica gel under the foam and sealed around the base,

Will the glue melt or soften? I've worked on a couple vibrator radios way

Hi everybody.
I've got a strange problem regarding my CompactDisc-Player DX6810 by
Onkyo. When I insert a disc, it spins up for about 3-4 seconds and
then simply runs out. It isn't stopped, the spindle motor just stops
turning. The track display then reads "0" and nothing else is
displayed, i.e. the calendar is empty and there's nothing like "no
disc" or else.

Here's what I've tried up to now:
- Changed the Pickup
- Changed the spindle motor
- Checked lubrication
- Checked FE and TE
- Checked the DC servos for spindle- and pickup-motor

Everything seems to be OK. I also watched the eye pattern on an
oscilloscope. It isn't a complete grid, but I think that is ok while
reading the TOC. Gain is ok and it's not overly noisy.
I also read the Troubleshooting-Guide by Mr Goldwasser from top to end
but now I'm stuck. Hope anybody here has some more ideas. I'll try to
support you as best as I can with more information or measurement
results.

Best regards and many thanks in advance,

Lasse

This model is not listed on the US Onkyo servicer's web site. Having
replaced the pickup may have introduced another problem, mainly that most
new pickups have a "solder short" which consists of two adjacent foil pads
soldered together so as to short out the laser diode and prevent
electrostatic damage during transport or handling. This solder bridge, if it
exists in your model, must be unsoldered for the new pickup to work.

On some cookers, that isn't strictly true.

To quote Galileo: "Nevertheless, it does move." Once upon a time,
microwave
ovens had a "stirrer", a fan that "moved" the standing-wave pattern around
the oven cavity.

Eggzackerly ! One of those references that I gave, also refers to rotating

Remember those old Philips machines? where the magnetron was at the
bottom and fired the magic rays into an aluminium 'fan' which was
mounted beneath the glass floor of the oven. the reflector was propelled
by the draught from the magnetron cooling fan whereupon the microwaves
were reflected upwards through the glass floor of the cavity and onwards
and upwards into the food.

Never saw one quite like that, but I guess that rotating 'reflector' is the
same principle as the motor driven 'stirrer'

Perhaps we should dub you "Clod Hopper". (Perhaps your posts are jokes, and
you're waiting to see who's the first to "get it".)

Microwaves do, indeed, "bounce around" within the oven cavity. There is
usually a standing-wave pattern with hot and cold spots, which is the main
reason for the turntable.


There`s a demonstration which I`ve seen, where a shallow plate of
something which looks like porridge is placed in a m/w and when the oven
is operated, you can see the wave pattern on the surface. I`ve also seen
it done with hundreds of neon lamps laid on the plater

The demonstration indicates nicely the hot spots and nulls in the
microwave coverage.

Ron
Put a cd in the mag, and the burn marks on the surface show the

wavelenght and hot/cool spots.
(as soon as you see sparking/smoke, switch off!!!! )
Add a cup of cold water to protect the mag from self destruct.

Mark,

I didn't use a new pickup. The "original" is still up and running, it
just needed a new lens. To make sure that it has no other faults, I
swapped it with another one from a Sony-player I found laying around
in our workshop. The Sony played fine w/the Onkyo-pickup and the Onkyo
still showed the same behaviour. The DX uses a KSS210A while the Sony
is equipped w/a KSS150A. Should've mentioned that; shame on me.
Hopefully you've got another idea.

Best regards,
Lasse

There's a spot there for questions like yours,

If that spot exists, it's not obvious.

A more specific link would have been nice.

FWIW, Office 2007 Student and Teacher Edition

That's $150 too much for commodity software apps.

In addition, I don't understand why people buy M$ products;
that money will be used AGAINST you
as Micros~1 purposely makes their products incompatible
--not only with competing products,
but **with it's own previous versions as well**
The MSFT attitude is
*Screw you if you don't buy into our perpetual-upgrade treadmill*.

It sounds like you make quite a bit of use of those types of programs,
so it's probably worth purchasing.

Disagree strongly.

The OP has already discovered that most non-vertical apps

If the OP hasn't discovered it yet, he will eventually find that
some documents generated with previous versions of M$ software
can't be opened with the current version of M$'s software.
OTOH,
OpenOffice.org has a reputation for being able to open those files,
making it **more** M$-compatible than M$'s own apps
(depending on your definition of "compatible").[1]

OOo 3.0 (just released) also includes support for .docx, .xlsx, .pptx,

This may sound like an asinine statement how ever, with the weak

You had said:

OK, then. They weren't new parts. Muddies the water still. If the spindle
motor's platter height is off, focus will fail. The height at which the disc
sits is critical. Could have a clamping problem, and I've seen some Onkyo
models have a cracked wormscrew gear which caused erratic playing and
startup problems.

If the spindle motor's platter height is off, focus will fail.

The new spindle motor came mounted on the supporting chassis with a
new
pulley already assembled. I think that the height is correct. Since
the player
behaves like before, the old motor should be still ok an not the cause
for the
problem.
How can I check the focus? AFAIK that's what the FE-Pin is for, but
there is
nothing to worry about. I've seen that signal clipping in other
players but that
is not the case here.

Could have a clamping problem

What is that?

There is no wormscrew in this one...
