Toshiba TV29C90 problem; Image fades to black...

Plus, the dangers are much exaggerated. From a few feet away from the oven
you'd probably just get a slight warming sensation. More people are burned
by heating pads - or boiling water from the oven.

Yes, but that "slight warming sensation" from a broken oven
is actually more dangerous than the surface burn from normal
heat sources. Your body is set up to detect and avoid burning
on the OUTSIDE. If a microwave emmiter is having enough of
an effect that you can FEEL it, then it's sunburning your guts.
You can take a LITTLE of that, but over time it can cause
a fair amount of internal damage, and you won't even know it,
until and unless it kills you.

... would being in a room with more than one
microwave oven running at a time, in general, be unsafe ...?

One of them is an 800 watt stand-alone unit and I believe the built-in unit to be
approximately 1000 watts.

Are they are on the same circuit? If so, then calculate the total
power consumption on that circuit, especially if other high power
appliances (eg toaster, electric jug) are being used concurrently. You
*may* find that your circuit breaker will be subject to nuisance
tripping.

Microwaves are used to warm piglets on demand. The piglets enjoy it. It's
people not piglets who do stupid things, like sticking their heads in the
oven.

Those piglets are all dead less than a year later, aren't they?

But not from microwaves, although it does make the bacon crispy after
they're dead! Mmmm! Bacon!!

Ok, this was way back in May, but I didn't work here in May. Wish I'd
found it earlier, because no doubt you've found a source.

JKL has a 3mm x 360mm. Not close enough? 2.5mm short on either end is
practically nothing. Mouser doesn't have it, but Digi-Key does.

Hi,

Mine is doing the same thing, except it is doing 15 short flashes of
the green light and one long inbetween.

What does this indicate?

Thanks,
Rich

Don't put your head inside either and you'll be fine.

 

Hi!

Using two or more microwave ovens in a single room will not be
hazardous, so long as both units are in good repair and don't have
anything broken around the door.

The biggest problem I could see occuring is an overload of the wiring.
If you want to run both microwaves in the same room at the same time,
make sure the wiring is up to it and use separate circuits for each if
available.

Can anyone help with this problem,

Checked out this 56" set it had blown a 5 amp fuse so I replaced the
fuse. Now the set works fine, but the convergence is all screwed up, where
should I look to find the problem......is it in the convergence board ??
or the main board ??
What voltages should I check for ???

I have serviced tv's for over 10 years, not overly familiar with rear
projection and the convergence circuitry. I have a good idea how it
functions, though.

Thanks

Do not know about USA but in UK these leads have fuse in them, mostly

What can happen in a Computer that will cause fuse in cable to blow up?

shorts

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

that probably varies by country to satisfy local laws

What could be HP's assumption?

it's probably following the law

If you hooked 5 AC generators in parallel and started them up at random

All,

For those interested in the denouement of my plight... Thanks
to the advice on this forum, I was able to track down the FM
antenna wire. Putting it to ground (as suggested) caused the
radio to put out a bad rasping noise. Instead I clipped the wire
off as close to the PCB as I could -- thus limiting the amount of
signal getting to the tuner/amplifier. This did not completely solve
my problem because the radio would still pick spurious music,
warbles, etc when between stations or at the extreme ends of the
dial. So what I did was to tweak some adjustable POTs and
inductors near the tuner and I was able to shift the band off scale
so that when I tuned it as far right as it could go, no stations could
be picked up at all, just a pleasant hiss to nudge me awake in the
morning ;-)

I pity the poor guy who might pick it from your trash when you finally
dump it. "What in the heck happened to this radaio?"

5 microwaves,
aligned them all to "air at the same target in a makeshift microwave. As
they measured the microwave radiation from different points, what they
recorded was in fact startling to them. The microwaves cancelled each other

I'm sure many lower quality/price restaurants often run several at the

AND it has a defective door you have nothing to worry about as far as
stray radiation. And it's not like it's stray x-rays, it's just radio
waves.

I agree that it's probably safe, but your argument here sucks.
1: The microwave frequency is specifically designed to cook meat.
If you happen to be living in the meat in question, cooking
it is clearly bad. You can do fairly significant long-term
dammage to yourself without becoming uncomfortable, by exposing
yourself to microwaves.

The good news is, the levels of such radiation that escape the
confines of a properly working microwave are so low that, with
the added defense of the inverse-square law, its's almost impossible
to get enough of them close enough together to do any damage.

I'd like to know just what about my "argument" you think sucks. I
very clearly said "unless you are standing VERY close to the microwave
AND it has a defective door you have nothing to worry about. Which
is pretty much exactly what the web page you cite says.

And if you think there is some danger realistically worth worrying
about in regard to two microwaves how about posting a link to a
verifiable story of someone being injured from even ONE PROPERLY
operating microwave. Like almost all "dangers", the dangers from
microwave ovens are grossly overstated by lay people and others.

Not even "if available"? I would think that two normal power units on
the same 15 amp breaker would pop it rather frequently.
