Explanation of diagram 2.1
Type numbers of transistors and ICs are indicated on the diagrams. If the position is followed by an asterisk the spare part number must always be used because the component in question has been specially selected, e.g. IC4*.
Component print and coordinate system
The largest PCBs have component prints and a coordinate system on both the primary and the secondary side.
On the diagrams every component has a coordinate number.
This indicates in which coordinate on the PCB the component is situated. The coordinate numbers are written in smaller print types than the position numbers.
= C27 is placed on the primary side in coordinate 1A.
= R10 is placed on the secondary side in coordinate 2B.
Control circuit
In certain control circuits the active mode is indicated by a function term or by an abbreviation. This may be e.g. ST.BY. = low in the stand-by mode or ST.BY. = high in the stand-by mode.
Wiring connections
The wiring connections on the diagrams are assembled in ‘bundles’. The individual wires are provided with one of the following codes:
INTERNAL CONNECTION ON ONE DIAGRAM PAGE
Internal connections on a diagram page are indicated by a number.
The bend of the wire indicates in which direction the other end of the wire is found.
CONNECTION TO ANOTHER |
DIAGRAM A |
DIAGRAM C |
DIAGRAM PAGE |
|
|
A connection to another diagram page is indicated by a number as well as by a letter of the diagram to which the connection leads.
Ground symbols
Three different ground symbols are used in the set.
= Ground
= Chassis
= Coarse ground
Symbol of safety components
When replacing components with this symbol, components with identical part numbers must be used. The new component must be mounted in the same way as the one replaced.
2.2Explanation of diagram
Measuring conditions
All DC voltages have been measured in relation to ground with a voltmeter with an input impedance of 10 Mohms.
The DC voltages are stated in volts (V), e.g. 0.7V.
All oscillograms and AC voltages have been measured in relation to ground with an oscilloscope or a voltmeter with an input resistance of 1Mohm.
AC voltages are stated in millivolts (mV), e.g. 660mV.
Caution
The use of any controls, adjustments or procedures other than those specified herein may result in hazardous radiation exposure.
The black and yellow label on the compact disc player serves as a warning that the apparatus contains a laser system and is classified as a class 1 laser product. The apparatus must be opened by qualified servicemen only.

Lithium battery
WARNING |
Short-circuit and overcharging of some types of lithium batteries may result in a |
|
violent explosion. |
|
When replacing the lithium battery in this set, note the following: |
|
Use only batteries of the same make and type as mentioned in this service manual |
|
(see page 3.9). |
|
Place the battery exactly like the old one. |
Explanation of the fuse symbols used in the set
Replace with the same type 1 ampere 250 volts quick acting fuse.
Replace with the same type 2.5 ampere 250 volts slow acting fuse.
Explanation des symboles de fusible utilisés dans l’appareil
Remplacer par un fusible rapide de même type et de 1 ampères 250 volts.
Remplacer par un fusible retardè de même type et de 2.5 ampères 250 volts.
