Self-diagnosis display
This system has a Self-diagnosis display
function to let you know if there is a system
malfunction. The display shows a code made
up of three letters and a message alternately to
show you the problem. To solve the problem
refer to the following list. If any problem
persists, consult your nearest Sony dealer.
C11/Protected
The MD is protected against erasure.
Remove the MD and slide the tab to close the
slot (see page 16).
C12/Cannot Copy
You tried to record a CD or MD with a format that
the system does not support, such as a CD-ROM.
pRemove the disc and turn off the system once,
then turn it on again.
C13/REC Error
Recording could not be performed properly.
pMove the system to a stable place, and start
recording over from the beginning.
The MD is dirty or scratched, or the MD does not
meet the standards.
pReplace the MD and start recording over from
the beginning.
C13/Read Error
The MD deck cannot read the disc information
properly.
pRemove the MD once, then load it again.
C14/Toc Error
The MD deck cannot read the disc information
properly.
pReplace the MD.
pErase all the recorded contents of the MD using
All Erase Function (see page 27).
C41/Cannot Copy
The sound source is a copy of commercially
available music software.
pThe Serial Copy Management System prevents
making a digital copy (see page 47).

HCD-CP500K/CP500MD SECTION 1
SERVICING NOTE
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
CAUTION
Use of controls or adjustments or performance of procedures
otherthanthosespecified herein may result in hazardous radiation
exposure.
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 repairing.
•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.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
break-down 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.
FOR CD
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 pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
FOR MD
NOTES ON LASER DIODE EMISSION CHECK
Never look into the laser diode emission from right above when
checking it for adjustment. It is feared that you will lose your sight.
This caution
label is
located inside
the unit.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety check before releasing the set to the customer:
Checktheantennaterminals,metaltrim,“metallized”knobs,screws,
and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuringthe voltagedrop across a resistor by means ofaVOM
or battery-operatedAC voltmeter. The “limit”indication is 0.75
V, so analog meters must have an accurate low-voltage scale.
The Simpson 250 and Sanwa SH-63Trd are examples of a
passiveVOM that is suitable. Nearly all battery operated digital
multimeters that have a 2VAC range are suitable. (See Fig.A)
