Note 1: Refer “NOTE WHEN THE AC BOARD IS REPAIRED”

(page 5) in servicing notes for how to distinguish TYPE
A/B.

Note 2: Refer to SUPPLEMENT-1 for the CONTROL, DIGITAL and

DSP boards of printed wiring boards, schematic diagrams
and electrical parts list of Russian and Ukrainian models.
When repairing the set of US, Canadian, AEP and UK
models, refer to either of original service manual/SUPPLE-
MENT-1 according to the set.

Note 3: Refer to SUPPLEMENT-1 for the CONTROL, DIGITAL and

DSP boards of printed wiring boards, schematic diagrams
and electrical parts list of Chinese model.
Refer to SUPPLEMENT-2 for the A-CLASS AMP, D-CON-
NECT and E-VOL boards of printed wiring boards, sche-
matic diagrams and electrical parts list of Chinese model.
When repairing the set except Chinese model, refer to
either of original service manual/SUPPLEMENT-1/
SUPPLEMENT-2 according to the set.

Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

Unleaded solder has the following characteristics.

•

Unleaded solder melts at a temperature about 40 

°

C higher

than ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350 

°

C.

Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

•

Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)

than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

•

Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

Replacement of IC3601 on the D-VIDEO board used in this set
requires a special tool.

AEP, Russian, Ukrainian and UK models uses only TYPE B.

Two types exist in the AC board for US and Canadian models.
Repair after distinguishing which type it is referring to the figure
below.

JW003

TYPE A : JW003 is not mounted.
TYPE B : JW003 is mounted.
