"Items you will need :

Set of small screwdrivers (computer repair set)

Soldering iron

Wooden toothpick

Solder

Everyone has experienced the moment when your headphones stop working. You jiggle the jack and they work fine until the day when jiggling the jack doesn’t work anymore and you can no longer hear anything. The problem isn’t your headphones, or that the player has stopped, but simply the solder on the jack has broken inside the case. You can learn to repair a headphone jack with a few simple tools.

Open the case by removing the screws that hold the case cover to the backing. Depending on whether you are repairing a headphone jack in a desktop, laptop or MP3 player, the screws will be located in different areas. Locate and remove all the screws. If the case does not pull free, stop and look for screws you missed.

Clean the old solder from the connection between the jack and circuit board. Do this by lightly touching the heated solder iron to the existing solder and then rolling the tip of a wooden toothpick in the soft solder to remove it.

Apply new solder to the connection. Hold the solder iron to the component pin (the pin exiting the back of the headphone jack) and touch the tip of your solder wire to the iron until the solder melts and forms a connection. Let the new connection cool for five minutes.

Test the player. Plug in your headphones to the jack and hit play. If you do not hear anything, turn up the volume. If you still do not hear anything, go back to Step 2 and begin again; your solder did not properly form a connection."

Work with a monitor that’s calibrated and profiled. for critical image editing, calibration and profiling are essential. otherwise, the image you see on your monitor looks different on other monitors or when printed.plan to use adjustment layers to adjust the tonal range and color balance of your image. adjustment layers let you go back and make successive tonal adjustments without discarding or permanently modifying data from the image layer. keep in mind that using adjustment layers adds to the file size of the image and demands more ram from your computer. accessing the color and tonal commands in the adjustments panel automatically creates adjustment layers.if you don’t want to use adjustment layers, you can apply adjustments directly to an image layer. remember that some image information is discarded, when making a color or tonal adjustment directly to an image layer.for critical work and maximum preservation of image data, it’s best if the image you work with is 16 bits per channel (16‑bit image) rather than 8 bits per channel (8‑bit image). data is discarded when you make tonal and color adjustments. the loss of image information is more critical in an 8‑bit image than a 16‑bit image. generally, 16‑bit images have a larger file size than 8‑bit images.duplicate or make a copy of the image file. working on a copy of your image preserves the original in the event you want to use the image in its original state.remove any flaws such as dust spots, blemishes, and scratches from the image before making color and tonal adjustments.open the info or histogram panel in expanded view. as you evaluate and correct the image, both panels display invaluable feedback on your adjustments.you can make a selection or use a mask to confine your color and tonal adjustments to part of an image. another way to apply color and tonal adjustments selectively is to set up your document with image components on different layers. color and tonal adjustments are applied to only one layer at a time. only the image components on the targeted layer are affected.
