ASSEMBLING OR WIRING
There are parts which use the insulation
material such as a tube or tape for safety, or
which are assembled in the condition that
these do not contact with the printed board.
The inside wiring is designed not to get closer
to the pyrogenic parts and high voltage parts.
Therefore, put these parts in the original
positions.
Please include the following informations when you order parts. (Particularly the CHASSIS CODE.)
1. MODEL NUMBER and CHASSIS CODE
YOU can find it in the back of your unit.
2. PART NO. and DESCRIPTION
You can find it in your SERVICE MANUAL.
When you exchange IC and Transistor with a heat sink, apply silicon grease (YG6260M) on the contact
section of the heat sink. Before applying new silicon grease, remove all the old silicon grease.
(Old grease may cause damage to the IC and Transistor).

ABOUT LEAD FREE SOLDER (PbF)
Distinction of PbF PCB:
PCB's (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 86

All products with the printed circuit board with PbF printing must be serviced with lead free solder.
When soldering or unsoldering, completely remove all of the solder from the pins or solder area,
and be sure to heat the soldering points with the lead free solder until it melts sufficiently.
Recommendations
Recommended lead free solder composition is Sn-3.0Ag-0.5Cu.
