"Sounds good. Because this involves turning the tv around (which
involves cleaning off the kitchen table) I'm saving this one for third, even though it sounds like something I can do" Haha, sounds like some of my houses. "The only degaussing coil I have came from a tv I destroyed. I never found a power supply for it, and right now I also can't remember where it is." You cannot just hook up an internal coil to AC, it will burn up before you can pull it away. Do you have a variac ? You can use that. Just put the coil in front of the screen, turn it up until you see the raster bend enough that there are black spots. you'll see what I mean. Then bring it down gradually, like over two seconds. If you manually degauss it with it on, Don't leave it cranked long, it only takes a second. It upsets some vertical circuits. Also, with a coil out of a set you will not really want to go to 120 volts, those things pull a hell of alot of amperage. If you go to say 100 volts AC, as soon as you switch it on start bringing it down quickly. Either way should work. Then just hope the connection doesn't intemittently make and screw it up again. But I don't think there was an earthquake**, so I'm figuring the aperture grill is still in the right place." An earthquake strong enough to dislodge it would have take the building off the foundation. It gets knocked out when the set is dropped usually, and it has to drop pretty hard to create enough G force. However sometimes it just happens on its own. They try to match the thermal expansion coefficients as well as possible, but you are talking steel and glass here and in fact in a Sony I think a couple parts are cast iron for whatever reason. |

"If you have a variac, wire a plug to the coil and plug it in. Set the variac for 50 to 60 VAC, plug your coil in and wave it around the front of the TV in a circular motion getting within 6" or so, then, continuing the motion, slowly back away from the TV until you get to a few feet away.
" I didn't realize you had already covered that because of the noise in here. I differ slightly, I think it would be easier to just gradually lower the variac without having to move the coil. With your way the coil might still burn up, with my way the process might get screwed up if the contacts in the variac are not in good enough shape. One time I had a Sony that looked like the colors were interpolated. If you are old enough you may have seen sets like Zeniths in which the grids (tube) or cathodes (solid state) were connected to those stake connectors which were identical. If you ever saw what happened when thos got mixed up, for whatever reason, this is what this set looked like exactly. A lightning strike had magnetized the CRT so evenly and strongly that the internal degauseer didn't cut it. The external degauseer did nothing. I had to connect the internal coil to a variac and turn it all the way up to what 135 volts, and then brought it down. That fixed it. Everyone had been scratching their heads on that one. It was really strange because the purity was actually good, just for the wrong colors. First and last time I ever saw anything like that. |

"When adjusting the " purity magnets " on a conventional CRT, one sets the
test pattern to red and tries to get a even red colour all over the tube face. " A note about that. On a delta gun CRT it would be better to adjust the blue and on an inline gun it would be better to adjust the green but red was chosen because the eye can discern it better. Actually on inline CRTs I learned how to adjust purity on a white field and convergence on snow (no signal). It works. However now it is just more useless knowledge. Now I am getting into the waveforms on the Ysus and Zsus. Tcon, logic board, LVDS. Where's that confounded yoke ? |

Magnets aren't good as John pointed out. It's best to keep magnets away from
CRTs, including older external speakers which don't have magnetic shielding. You could use an electric soldering gun (Weller or similar design) or possibly a bulk tape eraser. -- Cheers, WB .............. "micky" wrote in message ... Sounds good. Because this involves turning the tv around (which involves cleaning off the kitchen table) I'm saving this one for third, even though it sounds like something I can do. Thank you all. I've read all the posts as of last night, and I also like the idea of degaussing and of using a magnet to see what happens. Right now, I'm trying to remember where I keep all my magnets. I have all sizes but the only ones whose whereabouts I know are on the refrigerator. The only degaussing coil I have came from a tv I destroyed. I never found a power supply for it, and right now I also can't remember where it is. There are only two rooms in the basement. It has to be in one of them. But anyhow, I went on Freecycle to try to borrow a degausser. It worked when I needed a metal detector, although it seems borrowing is against the rules, and some moderators won't approve a request to borrow. So I say it's a request to be given and then I'll reccycle it again in a week, including to the original owner. . The other possibility is the shadow mask (aperature grill in a Sony) cut loose. There may well have been a current surge while I was gone (though nothing else looks bad, so far, and all the clocks were still right (Yeah, that's not a surge, but still.) But I don't think there was an earthquake**, so I'm figuring the aperture grill is still in the right place. When I get to the point of moving the tv, I'll turn the screen a little and see if that has a big effect. **We've only had one in 30 years here (Baltimore) and it was not much. However sitting in the basement at the work bench I could feel it, so I do get to cross earthquake off my bucket list. There is no fix for that, though I can do wonders with magnets around the bell of the CRT. The problem with that is that it might not be stable. Without a vow, I'll get back with results when I have them. |

That is 100% correct, and an adept description of how such errors are barely noticeable on a black and white picture. Understand also that we are talking pure CRT physics here. Don't get confused by colour signal weightings that are part of the encoding and transmission process. Whilst there are some differences in the efficiencies of the phosphors, and the eye is non linear in its response to the visible spectrum, those differences are not huge, and for white through shades of grey, the three beam currents will not be wildly different for a CRT that's in good emmissive order. Hence the reason that mass beam landing errors are not anything like as important to the reproduction of an accurate grey, as you might imagine. The fact that such errors are much easier to see on a colour picture may well be a perceptual one, as the human eye / brain combination, is extremely good at handling colour perception. Single beam landing errors - convergence errors - are of course, much easier to see on a black and white picture. I agree with all of the above. The only other possible extra point I could add is that purity adjustments are nominally made with a solid raster, and typical gamma for consumer color TV may cause compression / squashing / clipping of the video drives, making the impact of relative phosphor efficiency differences all the less noticeable.

Because you don't accept me as an authority (which you shouldn't -- or anyone else for that matter). Yet you obviously grovel in front of Peter Scheiber. I expect people to think think through stuff for themselves, and not blindly believe anyone. Anyone. But people generally refuse to do this, because it frightens them. In the case of phase shift, I could not remember the exact reason, so I spent my valuable time searching for you, and found a clear explanation from Michael Gerzon. Have you read the article? Do you understand what he's talking about? (I expect an answer from you on this.) Do you know who Michael Gerzon was? (No, of course not. You probably don't even know who Edwin Land was, even though, as you read this, you're probably sitting in front of a device one of inventions makes possible.) Gerzon arguably contributed more to our understanding of the psychoacoustics of surround sound, particularly with regard to recording & playback, encoding and decoding, than everyone else put together.

You seem to argue before you have carefully considered the information you have received. This shows a lack of respect for the people who spend their time trying to answer your questions. I might eventually go back to David Janszen for further information about driver modeling -- but it won't be until after I have thoroughly studied he pointed me do. The world is not obliged to give you a simple, easily digested answer for every question you might ask. Do you do your homework before you ask? I do. |

Phil As a forum for lively conversation, the internet is arguably unbeatable given its scope both demographically as well as the global reach, but sadly it does indeed create the very hollow and unconvincing exchanges you describe. On the subject of amplifier comparisons, I share your belief that much of the purported differences people supposedly hear and pay a huge premium to own are non-existent, or at least highly exaggerated. Biases arising from "golden-eared" pretentious reviewers add to the deception, as does the fundamental greed which causes dealers and manufacturers to create artificial claims and product distinctions which unwary consumers pay needlessly to own. Pretentious buyers and their egos are also ripe for being exploited. Simple differences in amplitude correlate highly with "goodness" in the ears of the uninformed. Some of the earlier studies on perceptual coding which were done at the onset of mpeg compression and other lossy techniques amply demonstrated how very easily the ear and brain can be fooled. The human hearing apparatus is an awesome and miraculous thing, yet it has virtually no memory nor quantitative ways to compare A/B, and is, in the final analysis, mediated by a very imprecise thinking and cognition process which is highly subjective and, to this day, not well understood. Human frailty and limited perceptual range put aside, we also have the ultimate issue of creating "high fidelity" simulations of things which never can be absolute. The Cleveland Philharmonic sounds a lot different in the orchestra pit than it does from the balcony. And the acoustic impact of a full audience on reflected energy may differ from season to season based on something as simple as heavier winter fabrics filling the concert hall. In the final analysis, any pretense that there is some form of "best" solution need only look at the same type of market-driven hype surrounding wines, cigars, gourmet foods, and many other discretionary purchases. The world is loaded with "experts" who pontificate and critique and extol and denounce, but they are, ultimately, narcissistic, have hidden agendas, or feel their judgement somehow matters more because they have a journalistic megaphone. Sadly, the internet has enlarged their audiences. End of rant-------------------------------------- |

It has one light bulb at the base of the heating element, but the element doesn't have two separated connections like the Weller does. Instead it has one thin 2,5" rod, a tube with a heating element and the return wire in it too. Do you think that is close enough to the Weller?? After my Freecycle request, someone wrote that a table fan will work as a degausser. He wrote "The fan I used had an induction motor** like the ones found on cheap turntables.The magnetism came off the side. It removed the mess a magnetized screwdriver had caused.(nephew: "Look at the neat patterns on the screen!")" Is this a risky idea? **Basically, an induction motor is any motor without brushes, right? Like almost all small and mediuml fans? |

"Smarty You are, of course, correct. Let me offer an apology to William and to this newsgroup for having provided at least half of the noise and argumentation here. The personal attacks certainly do not add to the body of technical understanding, and no doubt add confusion and anxiety needlessly. Ironically, I spend some amount of time with my grand-kids preaching fairness, absolutely no name-calling, and respect for others. And in fact, this very topic arose tonight at a birthday celebration, where my 5 year old grad-daughter was dealing with bullying at school. I will sincerely avoid all such activities henceforth in the spirit of going forward amicably, and again offer apologies to those whom I may have offended. ** Wot a wimp out. This newsgroups is chock full of ****wit trolls and William one of the worst. Word of advice: Never apologise to a troll - it only encourages them. .... Phil |

"micky" ** FFS stop wasting your and our time. Is the set's de-gaussing thermistor working or not ?? Does it go * BONG * at switch on or NOT ?? Odds-on it is the problem and when fixed the set will de-gauss itself. .... Phil |

But I don't think this tv ever went BONG, like one other did. Odds-on it is the problem and when fixed the set will de-gauss itself. That's added incentive to turn it around and take the back off. Thanks. ... Phil |

Almost all the circuitry is at main voltage - so you need an isolation tranny to work on them. ..... Phil |

"Arfa Daily" As to purity errors being visible on black and white pictures, other than the fact that the the phosphors have different efficiencies, and the drive levels are different for assorted reasons, it doesn't actually matter that much that the phosphors are being excited by the 'wrong' beams. The mix will still make something that approximates to white - or shades of grey - sufficiently well for it not to be glaringly obvious. More a sort of 'dirty patch' on the picture. However, as soon as a colour picture is viewed on the same gaussed up CRT, the error is immediately visible ** I am still using a CRT monitor for my PC. When I hold a speaker magnet about 6 inches away, white areas of the screen become mottled with grey shadows. However, the coloured parts change colour, blue to red, red to green etc. QED. .....

"Many moons ago, I came up with a simple demonstration that showed clearly
how a number of different make and model stereo power amplifiers sounded exactly the same. This was to clear up the notion strongly held by their various owners that each possessed its own, distinctive "sound". " Perhaps, but Bob Carver proved the opposite. |

I have read about his "mimicking" of a few high end US amplifiers by monkeying about with output impedances and bandwidths. There is no similarity with my test. All the amps used had very low output impedance and flat response (+/-0.5dB ) to 25kHz - same as 98% of all hi-fi power amps. .... Phil |

"William Sommerwerck" ** Of course it was intended as humour. WS takes everything so damn literally and thinks he can read people's minds based only on posted words. Of course it wasn't. ** I am being stalked by WS. Only people with a mental illness stalk others, on usenet or in real life. Only people with a mental illness try to punish those who were not sufficiently polite to them on usenet or in real life. Now I /am/ laughing. (Really.) Problem is, he means it. |
