It has nothing to do with my eyes. I might get a little "snow" on my
analog tv, but snow is far less irritating than all those huge
blotches and distortions on a HDTV when the signal is not 100%. Since
I live in a rural area, and am many miles from the tv station,
everyone around here has these poor pictures. Even on a DVD movie the
picture is artificial looking. I just dont like HDTV. But what the
heck. The government takes most of our money, they may as well take
away our tvs too.
I think you have some oddball bias that piggy backs on not having all
1) The government isn't forcing High Def. They're forcing digital.
Not all digital is high def. They also not forcing you to buy a new
TV. True, you'll need a converter for analog TVs that still are using
OTA reception (if that's still you, you're in the vast minority), but
it's not like you need to drop 2 grand on a new TV.
2) You don't need 100% signal for digital. There are also
alternatives to picking it up OTA if you live too many miles from the
station, including cable, or if you're still too far away from that,
satellite. Now, I find it interesting that you complain about
digital signals when you don't have digital service. Odd.
3) If you're basing your experience on friends, I've known MANY people
that have their TVs set up COMPLETELY wrong. I dated this one chick
that had a nice new 50" Sony HDTV, the Comcast guy hooked up the HD
box, but she had it on the wrong input, and was still only receiving
an analog-SD picture from the box. I clicked a couple of buttons on
her TV, and I though her head was going to explode with the huge
increased resolution change.
So what part of the HDTV picture don't you like? The increased
resolution? The greater dynamic range of black vs. white? Increased
So how is MS forcing you into a new operating system when you still
happily use Win 98? I mean, you're using a 10 year old OS. Home PCs
have only been around for 25 years or so.
What do you expect companies to do, stop developing the products they
make? Should GM still be making a '57 Chevy? Should we all still
have rotary telephones, using 300 baud modems? Still have tube black
and white TVs?
Until Bill Gates, Steve Jobs, or Jack Tretton hold a gun to your head,
they're not forcing you to do anything, as you've proven with your use
of Win 98 and a standard def TV.
Correction: broadcasters are being required to switch from analog
transmission (which is very wasteful of radio spectrum once you consider
the rules about adjacent channels (due to crappy UHF tuners)) to digital
transmission which uses less spectrum. The broadcasters may use that to
transmit HDTV, or multiple channels of game shows and reruns.
Your TV will continue to work fine playing content from your VCR or DVD
player. If you want content off the air, you'll need an adapter box.
But nothing forces you to buy a new TV.
But he didn't mention if they were big box style chargers or good ones.
I have a beefy charger that I have been using for years that I got
because it was declared inoperable. It had blown stud diodes and it was
a quick repair.
That is true. While I would expect someone with three of those
commercial units would not be sitting on three of them out of commission and
not repairing or having them repaired or at least having someone in the shop
that would know the answer to the question. Of course some very old ones
might require more redesign and expense to make it worth it. I would not
expect three of them to go out at the same time.
The OP appears to understand enough about them, that I am surprised he
did not know where to get the parts.
Of those 3, one was originally my own. The other 2 came from auctions
where I gave a couple bucks for them. The reason I can not just
change parts from one to the other is that they are all different
amperages. The thermal breaker needs to be a 12A (its a 2 or 10A
charger). None of the other chargers are even close, they are much
higher AMP chargers. I cant use the diodes from the 10A on a 50A or I
think the other one is a 20 to 30A. This is where the problems arise.
Getting parts these days is very difficult. Even when you do find
them online, many (or most) companies want a minimum order and or
charge very high shipping making the whole repair cost more than a new
charger. I did find one place that has the thermal breakers, except
they dont have a 12A. I have to choose either a 10 or 15, which means
a 15 or it will trip all the time at full charge. The part is around
four dollars. For some reason their shipping would not calculate on
the web which means I have to call them tomorrow, but I already have a
feeling the shipping will be $10 or more, which will make me ask
myself if it's worth the cost. (the item weighs .7 oz, so the real
shipping should be about $2). And I am not sure if they have a
What ever happened to the good old days when every city had a well
stocked electronics parts store? I recall them in the 60's and spent
a good amount of time and money at them, when I was in my teens.

I suspect that UPS Ground from DigiKey to most locations in the US would
be about $4 for their smallest size box and minimal content. Plus a $5
handling charge if your order is less than $25 or something like that.
They may charge "UPS Chart Rate" but get a big discount, which they
pocket to defray cost of the package, packing material, and doing the
packaging and also a bit of profit. Their parts prices are so low that I
see their markup over full "standard package" per-unit prices barely
covering cost of repackaging into smaller quantities and only some of the
other costs of getting them from a "standard package FOB manufacturer" to
your package of parts.
They have a highly automated system for that. It would cost them more
after cost of extra labor to send your package by first class mail instead,
probably at about $2 for postage. I have an impression that their
smallest box with packing material weighs about 5 ounces, plus the weight
of the merchandise. The automated system requires a small variety of box
sizes for the bulk of their shipments to minimize cost.
1. Electronics has largely been offshored by higher USA labor costs
(including labor overhead or USA-specific extra employee expense such as
health insurance at USA bloated healthcare cost rate, and auto insurance),
higher liability and liability insurance costs, and more-expensive-to-
comply-with workplace safety and environmental regulations. Have you seen
yet fire extinguishers with a flammability rating? I first started seeing
those around 2004 or so. For that matter, I think the rule book would get
fatter rather than thinner to get fire extinguishers an exemption from
whatever chemical product regulation gave us this!
So, there is little electronic prodct or electronic component
manufacturing in the USA now. I suspect a lot of DigiKey's customers are
hobbyists, prototype developers, consultants and specialty small job
manufacturers making a small quantity of actual products, and the small
remainder of actual electronic product manufacturers in the US, and a few
manufacturers of products that use a few loose electronic components (as
opposed to entire circuit boards). I suspect DigiKey also has some
Canadian customers including product manufacturers.
2. The local parts stores can't compete against DigiKey in any way
except by getting parts to you today rather than tomorrow.
DigiKey even goes a bit of the way there by accepting online orders as
late as 8 PM Central time and getting them to you the next morning.
Mouser is also doing some of what DigiKey does. The other main
electronic components distributors as far as I know are Allied-Newark,
Future Electronics, and Jameco. There are a few hobbyist/surplus type
places, and the ones that come to my mind most are Hosfelt, BG MIcro and
All Electronics. There are some local ones, but they are dying out to
such an extent that not every city in the US has one.

Seriously, you must live in a dream world. There are very few
servicable parts inside electronics now. In the 60's, you'd be lucky
to have a few transistors in a device, and probably 90% of the
components were capacitors and resistors. Which is why anything you
bought took up half your living room.
Cut to the 2000s, where your entire life can be kept on a phone that
neatly fits into your shirt pocket. A device that has a few tiny
surface mount components which never go bad, and 2 or 3 ICs that also
last forever (unless the phone happens to fall into the toilet!)
I'm all for fixing and tinkering, but we're in the very small
minority. I fixed a home DVD player which happened to have a cap go
bad (poor design, under rated component, as it was a common problem
with this certain model). Of course, when the DVD player initially
went bad, I bought a new one. One with some new great features (like
the ability to play MPG and AVIs off a standard CD or DVD ROM), for
$40. It took me longer to research the problem with the old DVD
player, dig a cap out of my supply, and solder the new one in than it
took to go to Best Buy and pick up my new fangled DVD player.
You don't HAVE to fix stuff now, because the replacement is dirt cheap
to buy. While bad for the land fills, it's a GOOD thing for pretty
much everything else.
On top of that, you STILL have electronic supply sources.. HUGE
sources like DigiKey (my favorite) that ship out within 24 hours.
Sometimes I get the stuff the next day.
