THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(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 M).
Circled numbers refer to waveforms.
Signal path.
F : AUDIO

d : TUNER
L : VIDEO
E : Y
a : CHROMA

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 (IC103, IC706) on the DMB12 board
cannot be used. Therefore, if the mounted DMB12 board
(A-1154-449-A, etc.) is replaced, exchange new EEP ROM
(IC103, IC706) with that used before the replacement.
Note: The components identified by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specified.
