A friend advises me to, instead, flick the iron away from you while you work. There are four resistors underneath the connectors and another four under first four that are actually zero ohm resistors, and they burn if overcurrent is applied.
And, voila, there was 12V at pin 1! You can use these 4-pin FAN connectors with existing crimp terminals already found on your wire, or you combine them with our original FAN crimp terminals.
Since the zero ohm resistor for pin 1 was burned, I used small soldering iron and very, very carefully applied small amount of solder to connect 2 pins of the burned out resistor. If your work will always be perfect, you'll never need one. I had an issue of flickering backlight at certain screen positions.
While the "flap" is pressed down, you pull out the wire. Maxmind free alternative dating hands This is a tee-shaped stand made of steel rod, with articulated arms and alligator clips at either end.
You will only need a small screwdriver, scissor, knife or similar small device with a thin tip. For high-end market, some manufacturers developed and launched IP cameras equipped with auto-Iris and P-Iris lens.

Knife For slicing things, improvising as a wirestripper, cutting shrinkwrap and housings to size, or opening stubborn plastic packaging. History This question is old, but since I have just had similar issue and repaired it, I feel I must contribute.
Anyway, during reassembly and testing, I accidentally shortened board and got a puff of smoke. This is best used in combination with desoldering braid see consumables list, below.
A small F-Stop is a large aperture opening and a large F-Stop is a small aperture opening. Unlike a DC-iris lens, the main task of the P-Iris control is not to continuously adjust the flow of light through the lens. The purpose is to wipe excess solder off the iron to prevent drips and messes.

Wire stripper For cutting and removing the insulation from the end of a wire. The iris is the part of the camera that has an adjustable opening to allow light to afinadores de violino online dating and fall upon the image sensor i.
The following consumables are mandatory for any soldering work. The board does not have fuses, so these serve as protection. I replaced the inverter cable one of the wires was pinched, but it was not visible until I removed protective tape.
Screwdrivers A variety of small sizes, both Philips and flat blades. If the Iris creates a larger opening, more light can get through; a smaller opening allows less light through. This is manufacturing precision at its best, which you also recognize in every aspect when you work with these 4-pin FAN connectors.
The primary objective of P-Iris is to improve image quality by enabling the optimal iris position to be set so that the central and best-performing part of the lens is used most of the time.
Reset SMC - disconnect power, remove battery and press and hold power button for more than 5 seconds. So you should get one. I tested voltages and found out that 12V from inverter connector was gone.
P-Iris is a new type of iris control that is both automatic and precise. The 12V power comes from the stabilizer on the right of the golden thing to the right of the connector. There are times you might be using both to bend something or pull it apart.
It will take you hours and a lot of stress, but it may also relieve you of stress! MOLEX typically only manufactures a darker blue shade and call it black, but our custom productions are always as black as technically possible. Laptop worked, but backlight was gone again, grrrr.

Normally, conventional IP cameras utilize fixed lens, or vari-focal lens to provide standard quality images. Press down the small "flap" on the top of the crimp terminal, which you access through the slots on the wide side of the connector, as shown on the second photo.
You can find full picture of the board here: There is also very useful video of similar procedure for MacBook board. Melt a bad solder joint with your iron, get the tip close, and trigger the pump to draw out the solder. Aperture is measured by F-Stop on your camera controls.
Use guide here on IFixit to dismantle MacBook replace inverter guidebut first check inverter cable.

The magnifying glass that many helping hands include can be useful too. Compared to all the no-name ones from China, this is just a different league.
My MacBook is A Penryn, the inverter is connected via 4-pin connector with the following voltages: Was this answer helpful? It was painstaking procedure, this LCD is not designed for bulb replacement, so I wonder that it worked!
If not the cable, then replace inverter using that guide. If there is no backlight at all, try all this, but first check voltages at inverter connector. If you have the budget, get a good-quality workstation unit with adjustable temperature.
IP camera adopts the most advanced iris control technology - P Iris, which allows keeping an accurate and consistent sharpness and depth of view. The special short-version guidance "wings" on these FAN connectors will not get in conflict with any heatshrink which is applied over the connector.

Because a smaller aperture limits the amount of light entering the lens, a large F-Stop also requires more light to properly expose an image. A damp cotton or wool but not synthetic!
The aperture is the size of the opening in the iris. For convenience, you'll probably eventually want to get a multimeter, discussed below.
Spending well can buy you an incredibly sturdy, highly reliable one, but the cheapest units are often reasonably stable.
Tip cleaner Commercially available tip cleaners are usually either small square sponges or balls of copper wool. This can be done with something as simple as a battery, small bulb, and some wire.
This is the default setting in an camera with P-Iris. Compared with Fixed or Manual Iris lens, Auto Iris lens used more advanced technology, camera with an Auto Iris lens are often more expensive. Should go without saying, but you never know. They always fit perfectly and go smoothly into the mating connectors.
This cools the solder instantly and it can be ejected as a metal slug.
