General Servicing Precautions 1. 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. Command Reference List Preset Sound Settings-sound Mode LGE TV test method followed, chassis. Desktop Pedestal Installation If manuwl circumstances create conflict between the following servicing precautions and any of the safety precautions on page 3 of this publication, always follow the safety precautions.
Turning On Tv Don’t show me this message again. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed to prevent potential shock reasons prior to applying power to the unit under test. It is not necessary to reapply acrylic coating to the areas. Unless specified otherwise in this service manual, lubrication of contacts in not required.
Clean the soldered areas with a small wire-bristle brush. Page 19 Check other set. Check other IC ex: It helps to make easily use realize “Plug and Play” function. Bend the two remaining leads perpendicular y manaul the circuit board. Positioning Your Display Do not connect the test fixture ground strap to any heat sink in this receiver.

Antenna Or Cable Connection Disconnecting or reconnecting any receiver electrical plug or other electrical connection. Inspect on the circuit board copper side the solder joints of the two “original” leads. The following techniques should be used to help reduce the incidence of component damage caused by static by static electricity.

Table of contents Service Manual Carefully bend each 1C lead against the circuit foil pad and solder it. Use mqnual this receiver only the test fixtures specified in this service manual. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
Always unplug the receiver AC power cord from the AC power source before; a. Draw away the melted solder with an anti-static suction-type solder removal device or with solder braid before removing the 1C. If they are not shiny, reheat them and if necessary, apply additional solder. General Guidance An isolation Transformer should always be 24lg30 during the servicing of a receiver whose chassis is not isolated from the AC power line.
Sound Setting Adjustment -user Mode 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. This is a flammable mixture.
When working with boards using the familiar round hole, use the standard technique as outlined in paragraphs 5 and 6 above. Not Using The Desk-type Stand Remote 42lg03 Key Functions 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. Page of 39 Go. Back Cover For Wire Arrangement Electrostatically Sensitive ES Devices Some semiconductor solid-state devices can be damaged easily by static electricity.
