Как доказала практика, конструктивная надежность данных компонентов обуславливает высокую практичность работоспособности всевозможной бытовой техники. В процессе ремонтных работ, которые все же случаются, возникает необходимость тестирования того или иного компонента на предмет его исправности. Например, как проверить полевой транзистор, который выпаяли из неисправного блока, вышедшего из строя аппарата. Самый простой метод проверки с применением стрелочного тестера. У исправного транзистора между всеми его выводами прибор показывает бесконечное сопротивление, кроме современных, имеющих диод между стоком и истоком, который и ведет себя, как обычный диод. Второй способ проверки с применение современного цифрового мультиметра. Черный щуп, являющийся отрицательным, прикладываем к выводу стока транзистора. Красный щуп, являющийся положительным, прикладываем к выводу истока. Мультиметр показывает прямое падение напряжения на внутреннем диоде около 450мВ, в обратном -- бесконечное сопротивление. В данный момент транзистор закрыт. Что мы делаем далее. Не снимая черного щупа, прикладываем красный к затвору, и вновь возвращаем на вывод истока. Мультиметр показывает 280мВ, т.е. он открылся прикосновением. Теперь, если прикоснуться затвора черным щупом, не отпуская красного щупа и вернуть его на вывод стока, то полевой транзистор закроется, и прибор снова покажет падение напряжения на диоде. Диагностика произведена, в результате чего мы убедились в исправности тестируемого транзистора. Для образца мы применили N-канальный полевой транзистор. Чтобы проверить исправность P-канального транзистора, необходимо, всего лишь, поменять местами щупы мультиметра.

#52: Tutorial / Basics of a Dip Meter
 
09:41
This video presents the basics of a Solid State Dip Meter, which is the more "modern" equivalent of the old classic Grid Dip Meter (GDO). The GDO was simply a vacuum tube based oscillator with a meter that read grid current as a measure of the oscillation strength/magnitude. The solid state dip meter uses a solid state RF oscillator and detector circuit to perform the same function. The Dip Meter (or Dipper) I show in the video is a Heathkit HD-1250 that I built as a kid in 1976 or '77. The dipper is mainly used to determine or measure the resonant frequency of a circuit, antenna, 1/4 wave transmission line, crystal, filter, etc. You couple the dipper's exposed coil to your "device" under test, and adjust the frequency of the dipper until a drop or dip in noticed in the meter. Once the dip is found, the frequency is read off of the dial. The theory of operation is that the signal from the oscillator is injected into the circuit/device under test. Then the frequency produced by the dipper hits the resonant frequency of the DUT, the strength of the oscillation will decrease due to the resonant load. There are a lot of applications for this: determining the resonant frequency of a circuit, or an antenna, of a crystal or filter, etc. Also, using known capacitors or inductors, you can use the dipper to help measure the values of unknown inductors or capacitors. You can determine 1/4-wavelength transmission lines and other resonant RF structures like traps. The meter can also be used as a RF signal source for testing receivers, etc. By turning the oscillation level in the dipper to the point where is just goes away, the dipper can then be used as an absorptive wavemeter - or a frequency selective field strength meter. The "Dipper" is a very flexible and versatile instrument, that has been around for decades, but isn't seen that often anymore unfortunately.

LG Philips TV Repair How to Find Plasma Panel Part Number Click Here to BUY TV REPAIR PARTS: http://www.shopjimmy.com *Some exclusions may apply Sustains (YSUS, ZSUS): http://www.shopjimmy.com/catalogsearc... Scan Drives (Y-Buffers): http://www.shopjimmy.com/catalogsearc... Logic Boards: http://www.shopjimmy.com/catalogsearc... Address Buffers: http://www.shopjimmy.com/catalogsearc... FOLLOW US: Twitter - @ShopJimmy - http://twitter.com/shopjimmy Facebook - ShopJimmy.com - http://www.facebook.com/ShopJimmy ..................................................................................................... Plasma Panel parts make up the majority of the parts inside of your plasma TV. Plasma panel parts include Sustain Boards, Buffers & Scan Drives, and the Logic Board. If the your Plasma Panel Label contains and LG or LG Philips logo, then the plasma panel parts will be identified using LG part numbers. LG & LG Philips Plasma Panel parts follow one of two part number patterns. The part numbers are printed on a label on the board. The part number will begin with EBR######## or 6871XXX###X (# being a number, X being a letter). Part numbers beginning with EAX######## or 6870XXX###X are generic board numbers and should not be used to search for replacement TV parts, as they will not guarantee compatibility. - Search Scenario #1: Your Search Returns An Exact Match Search your part number on ShopJimmy.com to find a compatible replacement. Typically, your part number will match the ShopJimmy Item Number. - Search Scenario #2: Your Search Returns A Differing Item Number If searching your part number directs you to items that have slightly different part numbers, take a look at the product details to confirm that your part number is in the substitute parts field. As long as your part number is found in the substitute parts field, this item will be a compatible substitute and will work in your TV. - Search Scenario #3: Your Search Has Multiple Results If searching your part number directs you to items that have slightly different part numbers, take a look at the product details to confirm that your part number is in the Substitute Parts field. As long as your part number is found in the Substitute Parts field, this item will be a compatible substitute and will work in your TV. - Search Scenario #4: Your Item Is Out of Stock If your part number is out of stock, be sure to check the Substitute Parts field on the product page for compatible replacements. These substitutes are guaranteed to replace your original board, even if the part numbers on the board do not match. ..................................................................................................... Top Common LGPlasma TV Problems: • Half Picture, Bad YSUS or Bad Y-Buffers • 6871QYH053A, 6871QYH053B, 6871QYH953A, 6871QYH953B Bad • Bad Logic Board • No Power, No Standby Light: Bad Power Supply Unit • 6871QZH056A, 6871QZH056B Bad • Power Cycles Off, Red Standby Light Blinks (Bad YSUS or Bad Main Board) • Bad Capacitors (Blown Caps)

Dream of the Moor
 
11:52
Dream of the Moor was composed in 1998, one of my earlier works. The video is made up entirely of paintings by the French painter Jean-Léon Gérôme (1824 -- 1904). You can see his complete works at: http://www.jeanleongerome.org Unfortunately, high resolution digital images of Gérôme's works are difficult to find. Low resolution images abound, but are not suitable for video production. Some of the paintings I wanted to include I simply couldn't find in a high resolution format, consequently they are omitted. Additionally, many of the high resolution images I did find show all the surface blemishes that are present on the original canvases, or else on the photograph made from the canvas that was scanned to create the digital image. Considering that all of Gérôme's paintings are now well over a century old, it's not surprising that they're showing a lot of wear and tear. However, no-one appears to have done much digital restoration on any of these images. I have done a little, but a complete job would be a daunting task, and represents more time and effort than I want to invest. Consequently, the smaller the window in which the video is viewed, the better will be the image quality. Catch 22... Messing around with color balance, hue, intensity, contrast and lightness are best left to someone who possesses a PhD in optics and art restoration, as well as having access to the original paintings. I have none of those things, but I'm still able to recognize that people don't have green skin, so if any original image I found on the Internet looked OBVIOUSLY awful, I used Photoshop to bring it at least within the bounds of "plausibly realistic". Gérôme's entire catalog is of course much larger than represented here. I selected those paintings I felt conveyed the spirit/intention/story behind the musical work. P.S. - I discovered one painting in my slide show that is NOT a Gérôme. Also, I found two other medium resolution paintings that I think should be included, so watch for an updated version coming soon (actually, I doubt anyone will notice ;-)

Sputnik TX nach DL3JIN erster Versuch mit 3,579MHZ Quarz
 
01:03
Da sich der 21,060MHz Quarz nicht zum Schwingen überreden ließ, habe ich hier einen Versuch mit einem 3,579MHz Quarz gemacht. Auch dieser schwingt nicht auf Anhieb, dazu waren noch zwei 20pF Kondensatoren direkt am Quarz nötig. Damit konnten dann die ersten Versuche mit dem Sputnik TX beginnen. Achtung: Die Schaltung im Original von DL3JIN kann so nicht für den Betrieb auf 80m verwendet werden dazu müsste noch der Gitter1 Kondensator(180p) deutlich erhöht werden. Aber für einen ersten Trockenversuch reicht es. Es zeigt sich aber auch das nicht jede Röhre und jeder Quarz auf Anhieb funktionieren(rein rechnerisch gesehen). Manche Röhre hat scheinbar nicht genug Eigenkapazität um ohne "Anschwinghilfen"(20-30pF) zu Schwingen. Ich untersuche die Sache weiter vielleicht gelingt es ja den 21,060 Quarz auch noch zum Schwingen zu überreden!
