PRECAUTIONSFOR USING LEAD-FREE SOLDER
1. Employinglead-free solder
Example:
Indicateslead-free solder of tin, silver and copper.
Lead-free wire solder for servicing
Ref No. Description PartsNo.
"MAIN, SMPS, HDMI PWB" of thismodel employslead-free solder. The LF symbol indicateslead-free solder, and
isattached on the PWB and service manuals. T h e alphabetical character following LF showsthe type of
lead-free solder.
2. Usinglead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional
lead wire solder may cause damage or accident due to cracks.
Asthe melting point of lead-free solder (Sn-Ag-Cu) ishigher than the lead wire solder by 40°C, we recommend
youto use adedicated soldering bit, if youare not familiar with how to obtain lead-free wire solder or soldering
bit, contact our service station or service branch in your area.
3.Soldering
Asthe melting point of lead-free solder (Sn-Ag-Cu) isabout 220°C which ishigher than the conventional lead
solder by 40°C, and as it has poor solder wet ability, youmay be apt to keep the soldering bit in contact with the
PWB for extended period of time. However, since the land may be peeled of for the maximum heat-resistance
temperature of partsmay be exceeded, remove the bit from the PWB as soon as youconfirm the steady
soldering condition.
Lead-free solder containsmore tin, and the end of the soldering bit may be easily corrected. Make sure to turn
on and off the power of the bit as required. If adifferent type of solder stayson the tip of the soldering bit, it is
alloyed with lead-free solder. Clean the bit after every use of it.
When the tip of the soldering bit isblackened during use, file it with steel wool or fine sand paper.
Be careful when replacing partswith polarity indication on the PWB silk.

CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT
[1] Notes On Schematic Diagram
[2] Types Of Transistor And LED
••
•
Resistor:
To differentiate the unitsof resistors, such symbol as
K and M are used: the symbol K means1000 ohm
and the symbol M means1000 kohm and the
resistor without any symbol isohm-type resistor.
Besides, the one with “Fusible” isafuse type.
Capacitor:
To indicate the unit of capacitor, asymbol P isused:
thissymbol P meanspico-farad and the unit of the
capacitor without such asymbol ismicrofarad. Asto
electrolytic capacitor, the expression “capacitance/
withstand voltage” isused.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
Schematic diagram and Wiring Side of P.W.Board
for thismodel are subject to change for
improvement without prior notice.
•
•
The indicated voltage in each section isthe one
measured by Digital Multimeter between such a
section and the chassiswith no signal given.
Partsmarked with “ ” are important for
maintaining the safety of the set. Be sure to replace
these partswith specified onesfor maintaining the
safety and performance of the set.
