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 |

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 |

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.

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. |

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.

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. |

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. |

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. |

[ Freon] However, I don't think that Mt St Helens caused lab rats to grow second tails or third ears... 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. http://msds.dupont.com/msds/pdfs/EN/...2f8000789b.pdf |

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. |

Ozone in the lower atmosphere, from automobile exhaust, etc, makes its way to the upper atmosphere only very slowly. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |

Science quiz, do you know where ozone comes from? 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. |

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. -- Bill Funk Change "g" to "a" |

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.

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? |

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*. -- Bill Funk Change "g" to "a" |

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? |

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. 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. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
