Ver. 1.1

Notes on Chip Component Replacement

•Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

•Keep the temperature of soldering iron around 270°C during re-

pairing.

• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering

or unsoldering.

UNLEADED SOLDER

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)

: LEAD FREE MARK

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 viscou-s (sticky , less prone to flo w) 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.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick­up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.

This appliance is
claassified as a CLASS 1
LASER product. This
label is located on the
rear exterior.

Note on DMB11 board replacement

New part of EEP ROM (IC103) on the DMB11 board cannot be
used. Therefore, if the mounted DMB11 board (A-1109-317-A, etc.)
is replaced, exchange new EEP R OM (IC103) with that used before
the replacement.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.

TEST MODE

HCD-GNZ5D

[Cold Reset]

• The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.

Procedure:

1. Press three buttons of x , [DISPLAY] and [DISC 1]

simultaneously.

2. The message “COLD RESET” is displayed, and the set is reset.

[T uner Step Change]

•A step of AM channels can be changed o ver between 9 kHz and
10 kHz.

Procedure:

1. Press the `/1 button to turn the power ON, and set the function

to TUNER/BAND “AM”.

The Mirror Time and IOP measurement allows you to make
diagnosis and adjustment simply by using the remote commander
and monitor TV. The instructions, diagnosis results, etc. are given
on the on screen display (OSD).

The Mirror Time and IOP measurement is required is such events
where servicing a DVD-Player includes changing the Base Unit
(BU). For each new BU to be used with a certain MV-044 board,
Mirror Time and IOP measurement need to be carried out.

This adjustment is made to satisfy the NTSC standard, and if not
adjusted correctly, the brightness will be too large or small.

Procedure:

1. Connect an oscilloscope to CN105 pin 6 (RFMON) and
CN105 pin 3 (GND) on the DMB11 board.

2. Turn the power on.

3. Set the test disc (refer to the TEST DISC LIST) on the tray
and press H button to playback.

4. Confirm that oscilloscope waveform is clear and check
RFMON signal level is correct or not.

Note: A clear RFMON signal wa veform means that the shape “◊” can be

clearly distinguished at the center of the waveform.
