It's not just spoiling a joke. There are allot of people who will take this
seriously. Jay Leno's Jaywalking proves how many people will buy into this
crap. The same people who think "Denzel Washington was our first President"
or "America was founded in 1976".

I'm having a hard time with that. Granted the laser inside the DVD
player is harmful but unless you looked directly at the laster, you
won't be harmed by a cracked case. I've had the case off of my DVD
player for a few days when I was trying to get the spindle working and
I'm doing fine.

There is no way the radiation from the player can killthe whole family.


Being a physics teacher, let me explain something.

A laser can go through the smallest hole, and if the disk is rotating
inside, the laser beams can be reflected at millions of different
angles, and many thousand times per second. Thus the laser beams
could spew out of that crack like bullets coming out of a machine gun.
Anyone in the path of these beams are instantly history. So, yes it
can kill a whole family and even a whole stadium full of people in
seconds. Lasers are dangerous and if one gets out of control, like
apparently this one did, there is no telling who or what will be
killed or destroyed.

God help your physics students.

From the Livewire Newsfeed

August 4, 2003

A New Mexico family was killed by a DVD player last Friday.
Authorities reported that it appeared that the DVD player had just
been purchased. Apparently an accident caused the player to fall off
the television set in their living room. It is suspected that the
family cat possibly knocked it down. The plastic case of the DVD
player became cracked during the fall to the floor, emitting the fatal
radiation which killed the entire family of seven.

Authorities were notified on Saturday when a relative came to visit
and found the family car in the driveway and no one would answer the
door. When the police arrived they used forced entry and were shocked
at what they found. There were dead bodies laying all over the living
room floor, including the husband, wife and five children. None of
them showed any signs of physical abuse, and all other possibile
causes of death have been ruled out. Authorities are positive the
deaths were caused by the DVD player.

Additionally, the first officer to enter the premises was struck down
and affected by the harmful radiation, and is hospitalized in critical
condition. The electric company was summoned and disconnected the
power to the premises before further action could be taken.

A cat was found laying right next to the fatal DVD player, which leads
to the suspicion that the cat was the cause of the player falling off
of the television.

Names of the family members are being withheld until further
investigation and notification of relatives of the deceased.
Funeral arrangements will be announced shortly.

Well, he's done it again. A spoof post so obviously intended as a joke has
sucked in supposedly intelligent technically minded folks into thinking it's
a genuine case, and yet again we get a flood of ill-tempered technical
rebuttals. Jeez, my 10 year old daughter read it and realised straight away
it was a laugh, nothing more. What the heck is wrong with you people?

There's obviously a need for some of you to get out more, relax and smile
once in a while, if you don't find this guys posts amusing, fine. However
responding in a serious manner just makes you look like nerdy idiots.

DVD players do not emit radiation.

Like CD players, they do have a low power laser, but the power is so
miniscule you could look right into it with no risk of harm.

I think the source of this troll is pretty simple...

[Jerry G.]

To replace the tuner, the main circuit board of the set must come out.
The power supply is part of this, and can be dangerous if you are not
familiar with proper procedures. There may be cable harnesses and etc
that must be disconnected to gain access to the remove the main board to
work on it.

The old tuner must be properly unsoldered from the board without
damaging the traces on either side. The new one is then inserted and
re-soldered back.

After replacing the tuner, the tech is supposed to verify that the
supply voltages to it are correct. He may have to re-initialize the
channel setup to get it going.

In the end, I would advise the non experienced to not do this. You can
not only end up damaging the circuit board, and or causing other damage
to your set, but also be injured! If you damage the set, naturally you
will loose the cost of the tuner, and the scrap the TV set, or have a
much more expensive repair to do. But, if you have an injury, this is
another matter.

In the re-assembly of the set, if you do not do something right, or not
proper check things out, there is the electrical safety aspect for
grounds, connections, or of a wire is running across something that runs
hot, and may cause a fire hazard.

I tell people that they should leave the proper jobs for the
professionals who do this all the time, and can be responsible for what
they do.

I have a Toshiba CF35F40 that the tuner has gone bad on. I've had a
Best
Buy repairman out to look at it and he determined that was the cause.
However, after about a year he has repeatedly told me that the part is
on
back order through Best Buy and suggested I go through another method to
obtain the part. I was able to order the part through Sears and will
have
it in a few days. Sears will charge me a minimum of $96 to come out and
put
the new tuner in (it may be more, they haven't come out yet.)

My question is: how hard is it to replace the tuner on this unit if
anyone
is familiar with this particular model or how hard is it in general to
replace the tuner? I've done a little research and there can be some
scary
electricity in the back of a TV in certain places and I don't want to
fry
myself to save a $100. However, if it is a simple solder or two around
nothing dangerous, I'm willing to give it a shot (hey, it's broken
already
right?) I'm used to repairing computers at the component level but the
power supplies on those things will only give you a nasty shock, not
kill
you (at least they haven't killed me yet.)

Any advice would be greatly appreciated.

Thanks,

False. Lasers that are powerful enough to "instantly" kill
even one person are much larger than anything that could fit
into a DVD player. Not to mention the fact that they cost
many times what a DVD player costs, so no manufacturer would
install a laser that powerful in any DVD player. Not to
mention the fact that they require far more power than a
typical house circuit would allow before blowing the fuse or
breaker.

If it were actually possible to build a fatal laser small
enough to fit into a DVD player, cheaper than the cost of a
DVD player, using less than 15A of power, then by now, people
would be shooting other people with them. Or, even better,
using them for various useful purposes such as welding.

Without any repair experience and the proper tools this is NOT a job you
should be doing yourself.... you could easily screw up your new Tuner part
and the television circuitry..... and then the repair bill at a shop would
be much higher.
Most of the $96 that Sears wants to charge you is for coming to your
home..... if you can buy lunch at McDonald's to have a friend to help you,
you could save a lot of money by carrying in the television to a service
shop.
Someone has to pay for the van, insurance, gas, travel time, etc...... and
that someone would be you..... TAKE it to a shop...... or pay the money
to have them come to your home..... the choice is yours, whatever works for
you.

They don't really use any large capacitors or anything I believe. Yes they
use a "capacitance" technology, but it's something about the changes in
electrical charge between the spinning disk and the stylus. We're talking
static electricity levels, I think.

Besides, I once took a zap from about 10K volts worth of capacitors once
when building a science fair project and I lived to tell about it. Knocked
me to the floor on my butt, though! (Actually, I fell backwards onto the
cat's scratching post.)

You know what electricians say? "It's not the volts that matter, it's the
amps!"

Most auto parts stores have an alternator tester that checks the alternator and
voltage regulator. Cracked belts are best checked by eye.

thank you very much for replying!
just to clarify it's normal for the battery to drop a volt while it is being
driven?
(because when i left initially it had been at 14.2 or 14.3 and when i returned
(and turned off the radio and everything else EXCEPT for the engine) the
voltmeter read 13.9 (before turning on the radio, lights etc.)
thanks again

Difficult to diagnose based on your description of the actual problem
(vibrating/nearly dies at idle under load), but from your description of
voltages at the battery before starting, after running with load, and after
its charged, I would say your alternator appears to be operating as
designed.

Based on your description, I would suggest looking at the plugs, wires, fuel
injectors, air filter, and possibly the throttle body if so equipped.

Good luck.

okay sorry...
14 year old car; automatic transmission, 1.6 liter engine

problem: when the car is in gear (drive, reverse, etc.) and stopped it
vibrates until one pushes the gas pedal... This does NOT occur while in
neutral or when in park.
It sounds as if it might stall and the idle is less than or equal to 1 X 1000
rpm.
when the radio is on and windshield wipers and i put the lights on while the
car is in gear and stopped, the vibration increases plus the lights dim if i
put turn on the ventilation.

i did a load test with the car cold and warm (before and after driving it)
cold
before starting, the voltmeter (on the battery) read 12.5 V.
starting it read 14.3 and adding (cumulatively) the lights, radio, interior
light, ventilation fan, and the windShield wipers, it went to ~ 14.2
Then i turned all the above off (except the engine) and it stayed at 14.2

warm
then drove around for maybe 45 minutes and when the car was in park (at home)
the voltmeter across the battery read 13.9.
(I did not turn off the car after driving it)
then adding back things cumulatively (as above), the voltage continued to drop
(staying at 13.x) but when i added the ventilation i couldn't get a steady
reading on the battery -- it fluctuated from 13.1 - 13.4.

after all was off (aside from the engine) it read 13.9.
Just wonder whether if i drove it for a several hours would the voltage
continue to drop?
perhaps 13.9 is normal (when the engine is warm / hot)?
and whether an alternator should be keeping the battery at 14.x for at least
45 minutes?
and how to tell whether the voltage regulator / alternator belt may be
involved.

sorry for the unClear post and hope this makes more sense
sincerely
Tanya

Hi All,

Thank you for all the replies, both in and out of group.
I admit with red cheeks, that I did not read my post properly,
and can only say that the "k" is next to the "l" (well noticed
Nigel, must have been a friedonion slip, but don't aplol
gise, I ruv a bit of mild p taking), but I did spell tacho
correctly twice, and I also made a,mistake in the motor ratings.
The current stated should have been 4.4 A not .4, ie 1KW approx'.
Is the efficiency of the motor so low, I often see 1 HP quoted as
700 ish watts and didn't think about efficiency.

I am trying to get some schem's from the manufacturer of one
of the machines to see what the tacho' is for, and if I do, I'll
share the info.

Nunce excretia in extractum est.

Many of the early UK front loading washing machines used multi
winding squirrel cage capacitor start and run induction motors. These
had typically a high power (about 1/3HP) 2 pole winding for the spin
cycle and a low power (about 1/8 HP) 6 or 8 pole winding for low speed
wash cycle. Because these were induction motors the natural speed
regulation was quite good and electronic control was not needed.

Later machines needed a lot more power for the high speed spin
cycles and these used high speed series wound commutator motors
because these can deliver much more power (1/2 to 1Hp short term
rated) for a given size and cost. The natural speed regulation of
series wound machines is inherently poor and electronic control is
essential for washing machine service. While crude form of speed
control is possible by sensing the back EMF of the motor this is not
good enough for the wide range of speed and loads needed for the
wash/spin cycles. Because of this pretty well all motors are fitted
with a "tacho" (tachometer) which is a very small (and very crude!) AC
generator which produces an electrical output directly proportional to
speed. A closed loop electronic speed control is used to adjust the
power input to the motor until it delivers the the desired speed
sensed by the tacho output.

Tacho output voltage or tacho output frequency can be used
to sense motor speed. Early controllers used discrete transistors and
a triac output. Later boards integrated most of the control functions
into a single IC - Motorola TDA1085C is typical.
