HDMI cable carries a protocol between the two ends asserting that they are allowed to
talk to each other. It is conceivable that your tv or the cable box is unwilling
to show it! This may explain the advice from the support person.

As others have said,
Component cables have no such fol-de-ra and will transmit anything.

HDMI carries audio. Using Component cables you have to add audio, I think.

Three thoughts here:

(1) It's not all that uncommon for some HDCP source devices (e.g.
cable boxes) to have difficulty negotiating properly with some
HDCP sink devices (e.g. TV sets) - a particular combination of
source and sink can fail to work, even though the same source box
works with different sink devices just fine (and vice versa).

Try exchanging the cable boxes (or TVs) between den and living
room, at least temporarily. See whether the problem goes away
entirely, or moves with one device or the other. If a U-Verse
box fails to work with more than one TV model, then you should
ask/insist that AT&T replace it.

(2) Switching to component video may result in a loss of some HD
programming. There are an increasing number of programs being
sent over cable and satellite which have DRM restrictions flagged
in them, which mean "No unprotected high-definition output of this
program is permitted". A program which can be shown in high-def
on a properly-secured HDCP device may be barred from display over
component video... or, the set-top box may display it after
down-sampling it to standard definition.

It is conceivable :-) that HDMI could deliver audio but you would still have to use
Component for the video. If the HDMI negotiation is rejected, do you get audio or nada?

Hi John,

I'm not claiming that this is what you *actually* experienced.
But, it is the sort of thing that is commonplace -- increasingly
so, nowadays.

E.g., I have a pair of Nakamichi Dragons (high end cassette decks,
now very "dated"). They are "autoreverse" decks -- when the
tape reaches the end of side A, side B is played (i.e., AS IF
the tape had been "flipped" -- though this is done without
any mechanical motion).

The tape counter, on reaching the end of side A, should start
counting *backwards* as it begins playing side B (i.e., the
counter should end up wherever it originally started once
side B is complete -- assuming you started at the beginning of
side A).

This is, in fact, how it works. There are two "play" buttons
on the deck -- "play forward" (side A) and "play backwards"
(side B). While play forward is active, you will see the
counter increasing. If you press "play backwards", the
counter will *decrease*.

*BUT*... if you stop the tape just as it reaches the end of side
A, open the tape door, remove the tape, flip it over (so, now
side B is "in front"), close the door and press "play forward",
the tape will COUNT BACKWARDS (i.e., as if the tape was still
installed in the deck playing "side B" BACKWARDS). So, the
tape MOVES "forwards" (the machine has no way of knowing that
this is "side 2" of the tape... it may be a completely DIFFERENT
tape!) while the counter counts BACKWARDS!

If you had stopped the tape a second BEFORE it reached the end
of side A, ejected it, flipped it, reinstalled it and pressed
"play forward", the counter would NOT count backwards.

I.e., this is a bug. (technically, a "race") Would you
expect that sort of thing in a $2K device? On something
so *trivial*?? :<

Doesn't instill consumer confidence in buying new expensive electronics!

D Yuniskis did a nice job but only touched on a few things that can go
wrong. In any case, my thanks to him for taking the time to explain the
issues.

Consumers are becoming more clueless as software takes over their lives.
This is a problem that is becoming more serious. If the doctors and nurses
and technicians in a modern operating room get confused or misled by
software glitches, it could be really, really serious. Has already
happened.

Yes, exactly. Coders are very bright (theoretically speaking) folks, but
they cannot see the future. Unanticipated, although normal, events and
other random glitches/failures can conspire to send controllers/chips into
endless loops or into a routine that is entirely inappropriate. We have
engineered ourselves into an untenable position. Anyway, for now, just shut
everything down and turn the devices back on using a recommended sequence
(good luck with that).

Google "Therac".

Unfortunately, there are no real safeguards in place to *prevent*
this sort of thing happening. There are "practices" that *should*
minimize the chance of it happening. But, there were "practices"
in place that should have prevented "Three Mile Island", etc.

Unfortunately, the folks designing these things have less and less
time, less and less *motivation* and less and less *capability*
for making "robust" products.

My DTV tuner shows *two* "9-1" channels.

Years ago, we would design devices that were (comparatively speaking)
*smart*. They could diagnose their own faults. They could assist
the technician in troubleshooting (set up scope loops, etc.).
Now, everything is reduced to the equivalent of an idiot light
"Service Required" -- and, often, that light isn't even present!
The device just "acts funny". And, since users often don't know
how it truly *should* work, they can't AUTHORITATIVELY complain/deduce
that it *is* malfunctioning.

(how many VCR's blink 12:00? Do you have to be a rocket scientist
to set the clock on a VCR???)

I have a Zune media player (movies, music, etc.). I am convinced the
hard drive inside it is dying. Instead of a diagnostic message to
that effect appearing on the LARGE, COLOR, FULL GRAPHIC DISPLAY, the
device sits there trying to read from the disk endlessly (locking
up in the process). "Um, if it can't get the data on the first,
second or even three hundredth attempt, what makes you think it will
get it on the 9 millionth attempt two days from now???"

Instead of helping the consumer determine that he has a p[roblem
(or, better yet, RECOVERING from that problem), it sits there
frustrating the user and leaving him with no alternative other
than to:
- call tech support (in some third-world country, no doubt)
- google for similar symptoms
- discard it in frustration

Well, if you meant that they are not willing to expend any effort to learn

I shudder at the amount of functional items that are returned, or re-sold,

Nor are they concerned about tomorrow, unless it's about their stock
options.

My DTV tuner shows *two* "9-1" channels.

The -1 channels here are not always available (high-def) and there is no
discernible rule of thumb to guide one as to why.

Toss it out. That's what too many folks are doing. Horrible!

But, you needn't "see the future" to code against these things!
All you have to do is step back (figuratively) and look at
your design and ask yourself: "What have I taken for granted,
here?" Then, go back and "UN"-take it for granted.

Of course, there are some things that you *have* to "assume".
But, far less than you actually usually *do* assume (at least
if you want a robust design!).

E.g., if you loan someone money, do you *assume* you will be
paid back AND HAVE NO CONTINGENCY PLANS FOR THE POSSIBILITY
OF *not* BEING PAID BACK? (if so, I'd like to speak to you
about a loan... :> )

Yes. And, most of those things aren't designed to *encourage*
comprehension. How many things have *no* power switch -- leaving
you pushing buttons wondering which will "turn it on"?

<shrug> I do volunteer work at a place that recycles "stuff".
I think we processed 1000 tons last year. Depressing to see
the things people just "abandon" (effectively) that still work.

Somewhere (and I'll be damned if I can recall where!), I saw an
article discussing natural resources. The point of the article was
"whatever is here is *all* there will ever *be* of these things"
(unless the alchemists succeed!). I.e., all of the Copper on
(in) the planet was formed when the planet was formed; we don't
"grow" copper to replace what we use.

For each of these resources (copper sticks in my mind), the article
described where it "was", currently.

IIRC, for copper, 1/4 of it is "in use"; 1/4 of it is "in landfills";
1/4 of it is "waiting to be mined/harvested"; 1/4 is unharvestable.
I.e., one way of looking at this is: we have used 2/3 of the copper
available to us, already (in the past ~100? years) and that half
of that is "in the trash".

There are other interpretations that are more pessimistic or less;
but, the bottom line is "there is only so much"...

Correct. OTOH, there is no motivation *to* be concerned about
those things. "It's someone else's problem"...

But why *two* of them (in addition to 9-2, etc.)...

<shrug> Again playing devil's advocate: what is the alternative?
Anything I fix "for myself" is "affordable" (for me). But, if I
have to fix something for someone *else*, it quickly becomes
prohibitively expensive to do so (I don't work for free). The
"system" assigns no cost to discarding items. So:

discarding + replacing <= keeping + repairing

Dell was not using "crappy" capacitors. What they were doing is the
same thing that almost every other manufactory is currently also
doing. They are rating their electrolytics as close to the bitter
edge of failure as possible. That saves a few pennies in cost by
using a lower voltage electrolytic but shortens the capacitor life. My
guess(tm) is that Dell's OEM supplier in China selected the capacitors
based upon faulty calculations, where it was designed to blow up in
about 5 years, instead of the 1-2 years specified in the class action
suit.

"Determining end-of-life, ESR, and lifetime calculations for
electrolytic capacitors at higher temperatures"
<http://www.dfrsolutions.com/uploads/white-papers/Uprating_of_Electrolytic_Capacitors.pdf>
At the bottom of the paper, note the various ways in which the ESR can
climb as a result varying conditions. At 105C (rated max temp), a
typical capacitor will have its ESR increase 5 times (and therefore 5
times the dissipation) after 3500 hrs of normal operation. For
24hr/day operation, that's only about 5 months of continuous
operation.

This has nothing to do with the original question, but I thought it
might be interesting.

I live in the forest in the Santa Cruz Mountains. When the wind blows

If it makes you feel any better (probably not, but worth a try), after
every storm, I get a few calls from customers with hung network and
entertainment equipement. DSL modems, cable modems, routers,
switches, IP phones, wireless, computahs, security systems, DVR's,
printers, TIVO, etc. Just about anything with a microprocessor inside
can be made to hang. D Yuniskis covered races and hazzards so I won't
go there. Add to that the joy of memory (RAM) glitches. When the
power fluctuates, one of the most sensitive components is the common
serial or dynamic RAM commonly found in almost everything. A
momentary magnetic pulse from a nearby power xformer is usually
sufficient to produce a large enough field to flip a few bits. You
may not even notice that a few bits have been flipped until perhaps
days after the power glitch, when the operating system decides to use
those memory cells, and finds them in a bizarre state. This is why
many servers have ECC (error correcting) RAM.

The problem of unpredictable processor operation is well known as are
some of the band-aids. For low end hardware, usually nothing is done.
Just power cycle the box if it hangs. Some clever programmers add in
a watchdog timer, which monitors the state of some manner of commonly
updated register (i.e. the RTC) and reboots the device if it goes
comatose. While clever, it's not very reliable as the dead-mans timer
is part of the same processor that it's trying to protect. An
external watchdog timer works much better. It usually receives a 1
PPS (one pulse per sec) signal from the processor. If that
disappears, it's reboot time.

It isn't just power line glitches that cause hangs. Cosmic rays,
alpha particles from radioactive components, external fields, and bit
rot all contribute to the general lack of uptime.

Anyway, try not to worry too much. Features and functions are added
faster than bugs get fixed, so reliability and uptime rapidly some
minimum acceptable value. This value is usually set by when the
support phone starts ringing. When the customer complaints arrive,
it's probably time to fix the problem. Otherwise, few people complain
about ocassional hangs, crashes, and reboots.

I don't think that applies to anything manufactured in the last
20 years... :<

Rather, I think it is a tradeoff of value for effort. E.g., my
TV has a clock in it. I've never set it. Reasoning: it's not
normally visible (I would have "to turn it on" to see it and
then it would interfere with the picture displayed; setting it
requires navigating through four or five screens of settings
(i.e., a bit of effort); and, it doesn't offer me any value
(that I can't get just by looking over my shoulder to the clock
that displays time REGARDLESS of whether or not the TV is on!).

I suspect most VCRs were used for watching movies instead of
timeshifting. In that case, there is no value to having the
correct time set (it may not even be visible while the movie
is playing!). And, since most VCRs wouldn't *retain* their
time settings in the face of power interruptions (power
outages, unplugging the set, etc.), it doesn't take long for
a clock to fall into the "ignored" category.

Finally, too many timepieces in a home ends up relegating most
of them to "un-maintained" -- how many of us have *a* clock
that we consider The Authority in our homes (i.e., we expect
some amount of error in all the others -- intentional or
otherwise)

My first job out of grad school in 1958 was with an R&D company,
Comstock and Wescott, in Cambridge, Massachusetts. Before WWII ("The big
one") the company's name was Kalmus, Comstock and Wescott, and I came to
know them as the developers of the Technicolor color movie process
through that association.

When I joined them one of the products they had already developed and
were trying to make a market for was a combination household
refrigerator and domestic water heater. The heater tank was on top of an
upright refrigerator and served as the condenser for the refrigeration
system, recovering the heat removed from the refrigerator. They had
named it "Stator".

AFAIK that product never made it to market, possibly because it was too
tall for the reduced ceiling heights prevalent after the war.

While I was working there they were also developing household heating
systems based on using off peak electrical energy to melt some kind of
salt with a high latent heat of fusion stored in multiple narrow
containers inside a "furnace plenum." The stored heat warmed air blown
over those containers and was used to provide forced air heating.

That one didn't take off back then either, but in the past year I've
seen reference to something under development (again) which sounded similar.

Thanks for the mammaries,

Jeff

If you're claiming to have done all this, how can you get it wrong about
something so simple as a modern battery tester?

Perhaps you're just living in the past.

This is the 21st century, use SI units.

What's the 21st century got to do with anything?

We (US) don't use those units (at least not in ordinary,
non-engineering, non-technical usage), thank you very much. (And yes,
lots of folks, myself included, like it that way.)

The record was set last millenium, and that was when I was there. I
appologize that you aren't smart enough to do the conversions.

Perhaps you live on a fantasy world.

Obviously, why else would you be the ONLY one with the "real" information?
