SERVICE MANUAL 19" WIDE TFT LCD TELEVISION WITH DIGITAL TUNER HDLCD1909 All the specifications and features are subject to change without notice. ORIGINAL VERSION (B) S/M CODE NO.
IMPORTANT SERVICE SAFETY INFORMATION Operating the receiver outside of its cabinet or with its back removed involves a shock hazard. Work on these models should only be performed by those who are thoroughly familiar with precautions necessary when working on high voltage equipment. Before returning the receiver to the user, perform the following safety checks: 1.
ABOUT LEAD FREE SOLDER (PbF) Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a PbF printing on the PCB. (Please refer to figures.) Caution: • Pb free solder has a higher melting point than standard solder; Typically the melting point is 86oF~104oF(30oC~40oC) higher. Please use a soldering iron with temperature control and adjust it to 650oF ± 20oF (350oC ± 10oC). In case of using high temperature soldering iron, please be careful not to heat too long.

DISASSEMBLY INSTRUCTIONS 2. REMOVAL AND INSTALLATION OF FLAT PACKAGE IC 3. When IC starts moving back and forth easily after desoldering completely, pickup the corner of the IC using tweezers and remove the IC by moving with the IC desoldering machine. (Refer to Fig. 2-3.) REMOVAL 1. Put Masking Tape (cotton tape) around the Flat Package IC to protect other parts from any damage. (Refer to Fig. 2-1.
DISASSEMBLY INSTRUCTIONS INSTALLATION 4. When bridge-soldering between terminals and/or the soldering amount are not enough, resolder using a Thintip Soldering Iron. (Refer to Fig. 2-8.) 1. Take care of the polarity of new IC and then install the new IC fitting on the printed circuit pattern. Then solder each lead on the diagonal positions of IC temporarily. (Refer to Fig. 2-5.)
