(most replacement es devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material). 7 . immediately before removing the protective material from the leads of a replacement es device, touch the protective material to the chassis or circuit assembly into which the device will be installed. caution: be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8 . minimize bodily motions when handling unpackaged replacement es devices. (otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an es device.) general soldering guidelines 1. use a grounded-tip, low-wattage soldering iron and appropriate tip size and shape that will maintain tip temperature within the range or 500 f to 600 f. 2. use an appropriate gauge of rma resin-core solder composed of 60 parts tin/40 parts lead. 3. keep the soldering iron tip clean and well tinned. 4. thoroughly clean the surfaces to be soldered. use a mall wire- bristle (0.5 inch, or 1.25cm) brush with a metal handle. do not use freon-propelled spray-on cleaners. 5. use the following unsoldering technique a. allow the soldering iron tip to reach normal temperature. (500 f to 600 f) b. heat the component lead until the solder melts. c. quickly draw the melted solder with an anti-static, suction- type solder removal device or with solder braid. caution: work quickly to avoid overheating the circuit board printed foil. 6. use the following soldering technique. a . allow the soldering iron tip to reach a normal temperature (500 f to 600 f) b. first, hold the soldering iron tip and solder the strand against the component lead until the solder melts. c . quickly move the soldering iron tip to the junction of the component lead and the printed circuit foil, and hold it there only until the solder flows onto and around both the component lead and the foil. caution: work quickly to avoid overheating the circuit board printed foil. d. closely inspect the solder area and remove any excess or splashed solder with a small wire-bristle brush. servicing precautions
lge internal use only copyright ? 2009 lg electronics. inc. all right reserved. only for training and service purposes - 5 - ic remove/replacement some chassis circuit boards have slotted holes (oblong) through which the ic leads are inserted and then bent flat against the circuit foil. when holes are the slotted type, the following technique should be used to remove and replace the ic. when working with boards using the familiar round hole, use the standard technique as outlined in paragraphs 5 and 6 above. removal 1. desolder and straighten each ic lead in one operation by gently prying up on the lead with the soldering iron tip as the solder melts. 2. draw away the melted solder with an anti-static suction-type solder removal device (or with solder braid) before removing the ic. replacement 1. carefully insert the replacement ic in the circuit board. 2. carefully bend each ic lead against the circuit foil pad and solder it. 3. clean the soldered areas with a small wire-bristle brush. (it is not necessary to reapply acrylic coating to the areas). "small-signal" discrete transistor removal/replacement 1. remove the defective transistor by clipping its leads as close as possible to the component body. 2. bend into a "u" shape the end of each of three leads remaining on the circuit board. 3. bend into a "u" shape the replacement transistor leads. 4. connect the replacement transistor leads to the corresponding leads extending from the circuit board and crimp the "u" with long nose pliers to insure metal to metal contact then solder each connection. power output, transistor device removal/replacement 1. heat and remove all solder from around the transistor leads. 2. remove the heat sink mounting screw (if so equipped). 3. carefully remove the transistor from the heat sink of the circuit board. 4. insert new transistor in the circuit board. 5. solder each transistor lead, and clip off excess lead. 6. replace heat sink. diode removal/replacement 1. remove defective diode by clipping its leads as close as possible to diode body. 2. bend the two remaining leads perpendicular y to the circuit board. 3. observing diode polarity, wrap each lead of the new diode around the corresponding lead on the circuit board. 4. securely crimp each connection and solder it. 5. inspect (on the circuit board copper side) the solder joints of the two "original" leads. if they are not shiny, reheat them and if necessary, apply additional solder. fuse and conventional resistor removal/replacement 1. clip each fuse or resistor lead at top of the circuit board hollow stake. 2. securely crimp the leads of replacement component around notch at stake top. 3. solder the connections. caution: maintain original spacing between the replaced component and adjacent components and the circuit board to prevent excessive component temperatures. circuit board foil repair excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds the foil to the circuit board causing the foil to separate from or "lift-off" the board. the following guidelines and procedures should be followed whenever this condition is encountered. at ic connections to repair a defective copper pattern at ic connections use the following procedure to install a jumper wire on the copper pattern side of the circuit board. (use this technique only on ic connections). 1 . carefully remove the damaged copper pattern with a sharp knife. (remove only as much copper as absolutely necessary). 2 . carefully scratch away the solder resist and acrylic coating (if used) from the end of the remaining copper pattern. 3. bend a small "u" in one end of a small gauge jumper wire and carefully crimp it around the ic pin. solder the ic connection. 4. route the jumper wire along the path of the out-away copper pattern and let it overlap the previously scraped end of the good copper pattern. solder the overlapped area and clip off any excess jumper wire. at other connections use the following technique to repair the defective copper pattern at connections other than ic pins. this technique involves the installation of a jumper wire on the component side of the circuit board. 1. remove the defective copper pattern with a sharp knife. remove at least 1/4 inch of copper, to ensure that a hazardous condition will not exist if the jumper wire opens. 2. trace along the copper pattern from both sides of the pattern break and locate the nearest component that is directly connected to the affected copper pattern. 3 . connect insulated 20-gauge jumper wire from the lead of the nearest component on one side of the pattern break to the lead of the nearest component on the other side. carefully crimp and solder the connections. caution: be sure the insulated jumper wire is dressed so the it does not touch components or sharp edges.
