All,

I have a DENON DCM-420 5 disk changer that is no longer reading any
disks on the caraselll. In the past, the sensor that reads the
carousel went out, we replaced that and all was well for 10 years.
Now no matter what disk position a CD is in, the device does not
reconise it as being loaded, it will run throught all of the positions
1-5 and then show 0 for loaded disks.

Is this something that can be fixed, am I looking at a sensor or the
laser its self.

Pleaes advise, I have had this unit for sometime now, and realy do
like they way it works, just don't want to give it up yet.

Symptoms and age would make for a pretty typical worn-out laser, but worth a
clean first, just in case.

I see you can get low-res TV's, Hi-Def TV's, and VCR/DVD combos at the
local Big Box Marts with digital receivers built in. In fact, they no
longer sell analog only TV's.

1. Do the digital receivers all function the same way or are there
different features/functions to be aware of? Any receiver brands that
are clearly better than others?

< snip >

I can't answer the question but I'll be looking to acknowledged experts like
Doug Lung
(samples at <http://www.tvtechnology.com/pages/s.0001/t.p0001.html&gt for
some hints.

Locally to this NG, Kirk Bayne is hot stuff in the info-gathering field. Is
a free plug OK?

My interest is in the so-called fifth-generation chipset from LG, tested a
few years ago and adjudged to be a significant improvement. I heard LG was
only going to put it in their own products, then I heard they would license
it. Heck, I don't know!

Thank you for all the advice!
You've given us the courage to tackle this ourselves!

Do get it right. A family recently died of carbon monoxide poisoning
in Providence due to a poor do-it-theirself installation / repairs of a
furnace.

the copper flex.

Hi Nate,
That dialectric stuff confuses me to no end.

The nipples already screwed into the top of the hot water heater seem to
have blue plastic inside them but they look like steel. I was actually
expecting two black steel female fittings in the top of the tank based on
what I saw at the store but this tank, when we finally got it out of the
box, has two whitish chromeyish nipples already screwed in.

Are you saying we can put the copper or stainless steel flex tubing
directly onto those two nipples sticking out of the top of the new hot
water heater?

If your pipes are galvanized you don't need di-electric fittings.

Hi Vic Smith,
THIS IS MY BIGGEST CONFUSION!
I see only *some* of the hot water heater replacement guides saying to use
the di-electric fittings while others ignore it totally. Our existing
plumbing has galvanized connected to flex tubing connected to nipple on the
hot water heater.

My guess is special tape/dope for NG is just bullshit to sell
expensive sealers, but do what you prefer with that.

I was wondering why some hot water heater repair guides said to use Teflon
tape (TPFE?) on the water lines but pipe dope (TPE?) on the gas lines yet
the tube that I bought says it works for both gas and water. That's
confusing. I was careful to only state in my hot water heater step by step
guide just what I had read in other guides, taking the best except where
they conflicted.

I use the same teflon tape for gas and water. As you've noted keep it
off the first couple threads so it can't get in the pipe flow.
I always look end-on to ensure that. Once inserted for tightening it
can't move forward.

Excellent hint! I'll add it to the tutorial as an additional step!
Thanks for improving the a.h.r hot-water heater tutorial for others to
benefit!

Unless it's the exact same tank, you will have to use different length
nipples. Until the new tank is in place, you are guessing.

Sigh. This was my biggest hurdle. Trying to get accuracy where there was
none. That's why we bought so many plumbing extras!

If you do it alone, do it when parts are available.

Yup. That's why we waited until after our morning showers on a Sunday. The
stores will be happy to sell us parts all day!

You may find some of the old pipes/fittings scaled up and need
replacing. Same with stop valves. This is the time to replace old
questionable stuff.

We agree. Strangely, the cold-water pipes are all full of crusty white
baking-soda like crud while the hot-water side seems relatively free of
scale. We're still replacing everything, including the old round green
twist gate valve, with newer better plumbing like the red lever ball valve.

Good luck. And let us know how it worked out.

Thanks Vic. I'd have to die trying in order not to report back to the
group. I'm the official photographer as Bill does the work (he hates my
flashing all around him) so I'll have complete step-by-step photos of the
job, starting from the fiasco when we tried to "save the box" the heater
came in.

Oh my! It was a disaster just getting the new hot water heater out of the
box, upside down, without damaging the box!

Yes.

Now I have it working , yes , its rate sensitive. Forte is loud.
Play a note too pianisimo and it fails to register at all, taking say 3
seconds or so from first finger touch to bottoming. I assume that is normal.

..41045 x cost per therm of gas x 365 / EF = yearly cost to operate

etc.

I would guess any engineer should be able to tell us what this 41,045 magic
number really is.

Here's a trick that might interest anyone who enjoys repairing things.

Every year the local cheapo store stocks "bug lanterns" which they don't
roll out until half way through summer because they know the blue
fluorescent tube won't last the distance! The ballast is badly designed -
consisting of a pair of parallel capacitors (1u & 0.56u) in series with a
parallel pair of 100 Ohm 2W resistors (for 240V).

When the lamp fails, the zapper voltage multiplier is still in GWO but a
replacement tube is Ł5 against Ł8 for a new lantern. Normally not a good
investment, but in view of the very short tube life something else can be
done.

To avoid the cost of a replacement tube it should be tackled before
failure, the units I have it was found that removing the ballast
components left enough space on the PCB to glue on a board salvaged from a
7W CFL, if one of the ex ballast capacitors is added to the electrolytic
on the CFL board it will have a very long life and the tube should be good
for a couple of years continuous use. An incidental benefit is energy
saving, when I opened the 7W CFL I found it had tiny TO92 transistors, so
the board is obviously not going to draw as much power as the original
ballast resistors which had burnt the PCB black!

There have only been two uses for A bug zapper that I know are worthwhile.
One is removing bugs from inside a screened porch. The other is to hang one
with the bottom removed over a pond to feed the fish. They are pleasant to
watch on a Summer afternoon though. I especially enjoy seeing knats fly
through them and come out the other side with a smoke trail following them.

Well, not quite. It doesn't say what model you're looking for, what
condition you require, how much you're willing to pay, where you are in
the world, or whether you'd consider another brand of similar features
and quality.

 

Do you have long red hair, ruby red lips, a shape like a NuGrape bottle?
