Default GE 8mm camcorder has snow in picutre, help w/diagnosing problem

Have a GE CG818 8mm camcorder. It's worked like a champ until today, suddeny
developed severe horizontal lines or snow.

Some observations regarding this malady:

-It's visible both through the viewfinder and from the composite out to the
computer
-It's visble in Rec mode.
-It's visible in play mode when not playing
-Banding *not* visible when playing a tape that was recorded before this
problem developed. Picture is fine in the viewfinder and through the
composite out when playing.
-It's visible on tapes recorded since problem began

Any guesses what kind of component might be causing this problem? I'd really
like to salvage this camera since it's worked great, is simple, yet has both
auto & manual focus.

Thanks for any assistance

Virtually any compact camcorder of that age will be suffering from failing
surface mount electrolytic capacitors. Often virtually every one is bad,
replacement is possible but usually runs a couple hundred bucks.

have you tried the simple things maybe you could re seat some of the
connectors and check solder connections. im not familiar with that model
so i dont know how old it is, if there are any pots make sure you clean
them, you can use wd40 but its slightly risky as few pots are made of
chemicals that break down in the presence of oil. depending on age , you
may have some bad caps, i usually look for any of the electrolytic type
that are bulging, or have already busted. above all - clean it well inside
an out, sometimes even dust can be conductive and will cause a lot of
problems

The heads are probably clogged up, run a cleaning cassette for about
3 minutes. Or take it to someone that knows how to do it and have the
heads cleaned by hand.

WHAT!!!
Look folks. Those dry cleaning cassettes are NOT, nor have they EVER been,
intended to be used for any more than TEN SECONDS at a time. And as far as
I'm concerned they are nothing more than a short cut to hell for video tape
heads. Three minutes of running a dry head cleaner will take off hours, if
not ALL of the life you have left on the heads.
Figure out how to open the recorder and give your cameras a good wet
cleaning with a good video head cleaner and a lint free cloth or quality
chamois stick. It is time well spent.

I think some manufacturers say to only run them for FIVE SECONDS at a time.

What?? (again!!)

He did say it was visible in REC mode. Correct me if I'm wrong, but
most videocams run a direct feed to the monitor - ie they do NOT read
the recording display off the tape - in REC mode.
So head cleaning, wet or dry, is unlikely to be the issue.

What I was told by a video repair guy was that to clean the heads, moisten
the cloth in clear acetone, and lightly rub across the heads perpendicular
to the axis of the drum but never rub up and down, i.e. never rub parallel
to the axis of the drum.

Since the camcorder is still useful in play mode, how I've "cured" the
problem is to find 2 more 8mm camcorders in a pawn shop that work great. An
RCA and a Sony Handy Cam. Got 'em both for $65. Geez, I thought I
practically stole the other one 5 years ago for $75. Hey, there's something
to be said for using technology that's on the downhill side of being
outdated.

That and the surface mount capacitors in those things are time bombs, even
sitting unused they'll fail after a shelf life of 5-10 years in most cases,
making older ones simply not worth much.

Actually, the "chamois-like" cleaning wands were created
specifically because "cotton bud"s (or cotton swabs, or
"Q-tips", a US brand-name) are SPECIFICALLY *NOT*
RECOMMENDED for cleaning rotary heads. The reason
being that the sharp little pieces that you are trying to clean
are quite likely to snag and retain cotton fibres which will
do more harm than whatever crud you were trying to remove.

They weren't using recorders with rotary heads "in Abbey Road
for years". For analog, linear machines (i.e. audio), they are just
fine. For that matter, if you are careful to inspect for stray snagged
fibres, cotton swabs are just fine for the non-moving parts of the
tape path of rotary-head machines.

But using them on rotary heads is just inviting disaster. And
many pro video users advocate avoiding them altogether just
because of the risk from stray fibres that you may not notice.

You could always try doing it the way we used to clean 2" machines...

Just squirt the freon in there while it's on the air!

Provided of course you HAVE a 2" machine...and the feds will let you have
freon...etc, etc, etc.

Then there is the "light application of a thumbnail to the upper drum"
trick.

Seriously though...dense cotton cloth or chamois stick, DEnatured alchohol
(the 70% stuff has too much water content...heads can rust, believe it or
not), and just hold the alchohol soaked cloth/chamois against the heads
while you carefully turn the drum with your finger.

DO NOT scrub up and down (you can snap a head off) or side to side (you can
knock the heads out of alignment.) Just hold the cloth in line with the
heads while turning the drum and check the cloth/chamois each time. It
should show less and less crud after each pass and eventually come up clean.

yes he did , if the video is distorted in record mode this is completely
independent of the tape mechanism/electronics, but concerning cotton buds,
regardless of what anybody says its better to just keep them off the
rotary head (use em on rollers and audio/erase head) that rotary head is
very sensative and in your case has nothing to do with the problem ,
however it never hurts to clean heads and i usually use a cloth that feels
pretty smooth, put a lil good old alcohol on it and rotate the head with
your finger at the top, dont apply much pressure to the side with the
cloth at all, just enough to bath it without snagging the cloth. make sure
you dry it or the next tape played will be swallowed.

In a few hours, Mt. St. Helens just north of town here put more

Freon to clean electronic parts. But, alas, its no longer politically
correct to observe that Freon was such a great cleaner/solvent.

I suspect that it would work equally well for DV, et.al. but

True, true...

However, I don't think that Mt St Helens caused lab rats to grow second

Freon did have it's dark side.

Considering the construction "quality" of some of today's consumer gear (and
even some "pro" gear) Freon may just be a little too "industrial" in nature.

Freon isn't a greenhouse gas, it reacts with ozone and is the cause of the
large hole above the arctic. There's modern equivilants that work nearly as
well and don't cause such a problem.

The MSDS doesn't mention anything like this.

"Reproductive data on rats show no change in reproductive performance."

"In animal testing, this material has not caused permanent genetic
damage
in reproductive cells of mammals (has not produced heritable genetic
damage)."

Freon did have it's dark side.


If you compare the MSDS, it is roughly equivalent to alcohol.
Actually, I am at far greater risk from alcohol (or those who
have consumed it) than from Freon.

True, but the tree huggers are trying to get a law passed to make it illegal
for Mt. St. Helens to give off any more gas .. still trying to figure out
who
is responsible though ...

Huh? Is it "tree huggers" or just someone trying to be cute? There was a
reasonably well publicized gag a few years ago where someone was pushing for
a ban on "di-hydrogen monoxide" and actually succeeded in getting a
ridiculous number of signatures.

You might want to read several articals in Physics Today in the last
few years. I'm only familiar with those because that's one I get, but
I'm sure that there are other scientific journals that have detailed
the chemistry that is responsible for these reactions. The process has
been well known in the scientific community for more than 20 years.

It remains a political question mark simply because it is inconvenient
to some parts of the political spectrum, mostly the same people that
have trouble with evolution, the heliocentric solar system, and the
concept of a round earth.

Ozone concentrations over both poles has been tracked for many years.
Naturally there is a normal variation from year to year, but the
current trend is way outside the norm.

Ozone concentrations over the north pole have also been tracked for
the same amount of time, but until recently there was never a "hole"
there. Now we have an annual hole. This is a distinct change.

Science quiz, do you know where ozone comes from?


Ozone is created normally in the upper atmosphere from the ionization
of O2 by the solar wind.

Ozone in the lower atmosphere, from automobile exhaust, etc, makes its
way to the upper atmosphere only very slowly.

Ozone is caused by diatomic oxygen molecules being busted apart by shortwave
UV light, they then recombine into Ozone (O3).

I can't *prove* that freon "caused" the ozone hole any more than I can
personally "prove" that the earth is round or that the moon is not made of
cheese, but it's widely accepted to be a substantial contributor. Yeah
there's a lot of BS environmental hysteria out there but there's some
substance to some of it. A quick google search brings up hundreds of links
to various reading. If the internet is not considered a trustworthy source
there's plenty of respected scientific books and magazines with coverage of
the subject at most libraries.

Since the manufacture of CFC's was banned in the US the world has not fallen
apart, technology has come to the rescue and developed suitable substitutes.

It's a distinct change *over the period of time we've been measuring.*
We havn't been measuring even an eyeblink of time yet, so all we know
is that it's a change in extremely recent history.
We have absolutely no idea of how much the ozone layers have changed
over even the last century, much less long enough to make some sort of
rational claim of an abnormal change over a long period if time.
Maybe when we have been measuring the ozone layers for even as short a
time as 50 years, we might find a cycle that's simply repeating.
But to make such a claim with such an extremely short data gathering
period is simply bad science.

You might try these sites to start with:

http://www.uneptie.org/ozonaction/co...s/02Oct15.html
http://www.epa.gov/docs/ozone/title6...ers/cons2.html
http://www.ausetute.com.au/cfcozone.html

After that there are literally hundreds of Scientific papers on the
subject. This is why refrigerator companies eventually replaced the CFCs
they used in the cooling systems of fridges and why there are so many
controls on the methods used in the production of Printed Circuit
boards, for example

I suspect that you must be the only person left in the free world that
doesn't know that chlorofluorocarbons (of which Freon is a major member
of the group)have been primarily responsible for the hole in the Ozone
Layer - which incidentally didn't exist prior to 1976.

Actually, the "hole" is over the Antarctic, not the arctic and does
fluctuate naturally. The problem with CFCs is that they are quite effective
at destroying ozone and are much more stable, so they stay in the atmosphere
for a long time. While they cannot be blamed for the existence of the ozone
hole, it seems foolish to keep producing and using substances known to have
such a profound and damaging effect, when substitutes are available.

Freon isn't a greenhouse gas, it reacts with ozone and is the cause of

the
large hole above the arctic.


Kindly demonstrate proof that use of freon "caused" the hole in the

ozone,
and that it wasn't already there and doesn't fluctuate in size on it's

own
due to natural forces.


It's not a fact in dispute - go look it up for yourself.

I'm sorry. I thought you were aware of the concepts of 'Ocean', 'Beach' and
'Wave. My bad for assuming that your intelligence was above that of a Jell-O

Not unless by "in dispute" you mean there's disagreement on the subject. If
you can tear yourself away from that tree you're hugging, put on your
Birkenstocks and look around, you'll find plenty of dispute on the topic.

It's not in dispute in the scientific community.


Ah, Mike Kohary, official voice of "The Scientific Community". And pray
tell, what is your official place in "The Scientific Community"? Looking at
your website - electric guitar, computer programming, video game nerd,
drinker of Samuel Adams, film buff - but gotta be honest chief, your
scientific credentials don't quite jump out from the page. Amazing that
there's no links, not even a mention of any interest or training in
environmental or any other science, chemistry, physics etc. considering this
keen interest/knowledge you seem to claim.

Couldn't be that you're simply spouting emotional rhetoric could it?

I am aware of such things. I'm trying to understand where this 50 foot
wave would come from.
Do you expect me to believe that a hole on the ozone layer would
somehow cause a 50 foot wave?
If so, would you please explain the mechanics behind this?

Actually, it *is* in dispute.
While we can *model* such, that doesn't mean it's happening the way
the model says it *can* happen.
And it's also in *much* dispute that the holes are anything other than
a natural thing hat we've never noticed before simply because we
havn't been monitoring the ozone levels for very long.

The scientific literature says otherwise.


No, the scientific literature that *you* read and give credence to
says so.
How long have we been monitoring the ozone layers?
How long have they been there?
What was their behaviour before we started monitoring them?
Any breakdown in answering those questions (especially the last) means
we just don't know what he current behaviour means. We only know what
it *is*. We don't know *why* it is. We *think* we may know one way it
could be this way, but without a better understanding of the nature
and history of the nature of the layers, we can not, with any
certainty at all, say *why* certain behaviour in them exists.

Some literature says it's out fault. This is a politically correct
attitude, and it *might* be right. The problem is we just don't
*know*.

Ok so it's possible that freon doesn't affect the ozone layer, on the other
hand it's possible that it does. There's suitable substitutes so why chance
it? It's possible that excessive UV has nothing to do with skin cancer, or
that smoking has nothing to do with lung cancer, or that living off nothing
but fast food won't make you unhealthy, but there's quite a bit of evidence
to the contrary, why chance it?

We havn't been measuring even an eyeblink of time yet, so all we know

It's true that the observation time is negligible in terms of the
earth's age. I'll grant you that. If you feel that only observation
over a significant portion of the earth's age will convince you, then
we will have to agree that you will never be convinced.

We have absolutely no idea of how much the ozone layers have changed
over even the last century, much less long enough to make some sort of
rational claim of an abnormal change over a long period if time.
Maybe when we have been measuring the ozone layers for even as short a
time as 50 years, we might find a cycle that's simply repeating.
But to make such a claim with such an extremely short data gathering
period is simply bad science.


It's important to recognize that in addition to the ozone
concentrations, the fluorocarbon compound concentrations have also
been followed. The chemistry is known and the reaction rates are
known. We also know when Freon first entered the lower atmosphere, and
the rates of diffusion to the upper atmosphere have been calculated
and verified.

The half-life of the fluorocarbons in the upper atmosphere is
extremely long, but it can be calculated, and the calculations agree
with the observed concentrations. The body of evidence is complete and
consistent. To my knowledge, all the debate on this topic withing the
scientific community was settled many years ago.

The claim that this may just be a normally occuring anomaly would be
reasonable if we didn't have additional data to support the
conclusions, but this is not the case. The claim of "bad science" is
really just the pot calling the kettle black. The science has all been
done; the fight is all in the political arena. Unfortunately, the
current political climate is more comfortable with faith than facts.
