Toshiba TV29C90 problem; Image fades to black...

Actually, I just found available LD3141 chips at dalbani.co.uk for about 4 bucks each.

does the OPA 2134 replace the Sanyo LD 3141, and does anybody have a
schematic for both?

Thanks.

No one has mentioned that cable mining is much safer and easier with laced cables and can be impossible with ty
wrapped cables.

New cables are laid into cable racks on top of old cables, and
the old ones that are no longer used are just cut off where they
enter the cable rack and left in place. Eventually, of course,
the cable rack fills up with old unused cable.

So every decade or so some poor smucks get the job of removing
all old cables. And that... is cable mining.

It isn't fun and it isn't exciting (but if you get the cable it
might be profitable though).

And if any of the cable was put in with tie-wraps, you also get
your hands shredded from the sharp edges where the tie wraps
were cut off. That is bad enough if a proper tool is used, and
*far* worse if some dingbat has used snips to cut them.

Spiral Wrap is pretty nice and robust but when it comes to
fault-finding broken wires etc it can be a bitch.
Have a look at this :

http://www.geocities.com/svxdc/AI-pics/254-11a-HarnAdapWrap.jpg

I find this better for dirty/oily environments or where there's a
chance of vibration. The the harnes is easly "moulded" to fit intricate
contours.

Another interesting development....

I took a few photos with the help of the AC adapter. Then unplugged the
adapter. Turned on the camera and the zoom starting cycling out 1/2-inch,
then back in 1/2-inch, back and forth.... The power switch had no effect on
it. Had to open the battery door and break the connection to stop the
cycling.

Am I on candid camera??!

Sounds like your voltage regulator circuit has a bad component such
as a leaky capacitor or defective zener diode.

This is not for the unskilled, but a square turn of copper can be shimmed
under the yoke to reduce width. Must be flexible of course.

Actually, in this case, it turned out to be something simpler - the
adapter/battery switch in the ac adapter plug on the camera had an oxided
coated on it. A little exercise and it wore the oxide off.
 
Which is your privilege. All I'm saying is you don't need to drag his name
(and yours too, by the way) through the mud. You are confused as to whom is
playing a game and being silly. Have whatever opinion you care to have.
When you feel that you must refer to people as "scumbags" because they don't
share your opinion speaks poorly of you and weakens your already-weak
supposition even more. It's sad that you consider respectful disagreement
"silly", and must resort to such tactics. I can't imagine why anyone would
regard your information any more reliable or trustworthy that the disturbed
personae you display in this forum.

Following a comment like:

with another one like:

would lead most people to conclude you can "dish it out, but can't take

Of course the GoDaddy registrar is an unimpeachable resource and there's no
way someone could ever, possibly, have filled in false information for the
registration of the "law firm" to discredit the other website. Just like
there's no way someone would fill in a bogus telephone number.

I don't recommend the resistor trick...I was bored one day last year and
played with this idea on a 20" RCA TV...yes a 1 ohm resistor in series with
the vertical yoke will reduce vertical size, but it had to be
enormous...over 20 watts to do the job without smoking... The inductive load
of the yoke - yes even the vertical... carries enormous current levels and
will give that resistor a real enema by dissipating most of the power of the
circuit in IT.

That brings back memories of the 50's...

While the document gives explicit details of "straight line" lacing of
a conductor wiring form (loom) it doesn't cover the all important
techniques used at single and double directional branches.

The art of lacing doesn't only apply to conductor wiring forms but
also to block lacing of a whole group of multi-conductor cables. This
was the art of grouping many cables into an octagonal block and fixing
it to overhead cable runways as in the old step-by-step exchange days
prior to the advent of pvc sheathed cables, cable troughing and
eventually overhead cabling mesh. As a trainee tech I remember
spending a whole week block lacing a group of 64 cables x 20 triples
(60w) into an 8x8 block in a complicated level change from high level
to low level (self supporting block in mid air) runway with several
bends in the final structure, only to have my supervisor cut the
lacing at every lacing point because it wasn't good enough. I was mad
as hell at having to do it all again and it took some time to mend our
relationship.

Hmm how about a capacitor? I was thinking it was a resistor but perhaps I
was wrong, I saw it in an old 1970's book about computer projects.

A capacitor that's larger than the monitor? What will that cost?

shorts

HP sells its servers with power cable that cannot have fuse in the

that probably varies by country to satisfy local laws


What could be HP's assumption?

it's probably following the law

I think you will find the fuse is also there to protect the cable as well
encase its cut through or a short on the cable the fuse does not just
protect the computer
