(In addition to this, the necessary note is printed in each block.)

•A: B+ Line.

•Voltages and waveforms are dc with respect to ground un-

der no-signal (detuned) conditions.

•Voltages and waveforms are dc with respect to ground in

service mode.

•Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal production

tolerances.

no mark : DVD STOP

*: Impossible to measure

•Voltages are taken with VOM (Input impedance 10 MΩ).

•Circled numbers refer to waveforms.

•Signal path.

•Abbreviation

E3 : 240V AC area in E model

RU : Russian model

For PrintedWiring Boards.

Note:

•X: parts extracted from the component side.

• a: Through hole.

•: Pattern from the side which enables seeing.

(The other layers' patterns are not indicated.)

•Indication of transistor.

Caution:

Parts face side: Parts on the parts face side seen from

(SIDE A) the parts face are indicated.

Pattern face side: Parts on the pattern face side seen from

(SIDE B) the pattern face are indicated.

✩New part of EEP ROM (IC1103) on the MAIN board

cannot be used.Therefore, if the mounted MAIN board

(A-1144-746-A, etc.) is replaced, exchange new EEP

ROM (IC1103) with that used before the replacement.
