Use of controls or adjustments or performance
procedures other than those specified herein may
result in hazardous radiation exposure.
WARNING!!
WHEN SERVICING, DO NOT APPROA CH THE LASER
EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS
NECESSARY TO CONFIRM LASER BEAM EMISSION,
BE SURE TO OBSER VE FROM A DISTANCE OF MORE
THAN 30 cm FROM THE SURFACE OF THE
OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.
CAUTION :
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH
MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS

After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
1.Check the area of your repair for unsoldered or poorly-soldered
connections. Check the entire board surface for solder splashes
and bridges.
2.Check the interboard wiring to ensure that no wires are
"pinched" or contact high-wattage resistors.
3.Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
4.Look for parts which, through functioning, show obvious signs
of deterioration. Point them out to the customer and
recommend their replacement.
5.Check the B+ voltage to see it is at the values specified.
6.Flexible Circuit Board Repairing
โข Keep the temperature of the soldering iron around 270หC
during repairing.
โข Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
โข Be careful not to apply force on the conductor when soldering
or unsoldering.
SAFETY CHECK-OUT
Unleaded solder
Boards requiring use of unleaded solder are printed with the leadยญfree 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.
โข Unleaded solder melts at a temperature about 40ยฐC 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 350ยฐC.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
โข 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.
โข Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

SERVICE NOTE
1-1. NOTE FOR REPAIR
Make sure that the flat cable and flexible board are not cracked of
bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
Cut and remove the part of gilt
which comes off at the point.
(Take care that there are
some pieces of gilt left inside)
When remove a connector, don't pull at wire of connector.
Be in danger of the snapping of a wire.
When installing a connector, don't press down at wire of connector.
Be in danger of the snapping of a wire.
1-2. DISCHARGING OF THE FLASH UNITโS CHARGING CAPACITOR
The charging capacitor of the FLASH unit is charged up to the
maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
capacitor is handled by hand. The electric shock is caused by the
charged voltage which is kept without discharging when the main
power of the MVC-CD500 is simply turned off. Therefore, the
remaining voltage must be discharged as described below.
1.Preparing the Short Jig
To preparing the short jig. a small clip is attached to each end of a
resistor of 1 kโฆ /1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to prevent
electrical shock.
1 kโฆ/1 W
Wrap insulating tape.
2.Discharging the Capacitor
Short circuits between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.

1-3. NOTES ON HANDLING THE LASER DIODE
[LASER UNIT AND BASE UNIT (DDX-G3000)]
The laser diode 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 breakdown 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.
1.Precaution for Checking Emission of Laser
Diode [Base Unit (DDX-G3000)]
Laser light of the equipment is focused by the object lens in the
optical pick-up so that the light focuses on the reflection surface of
the disc. Therefore, be sure to keep your eyes more then 30 cm
apart from the object lens when you check the emission of laser
diode.
