  All capacitors are in  F unless otherwise noted. pF : 

F.  

50V or less are not indicated except for electrolytics and tantalums.

  All resistors are in ohms, 1/4 W (Chip resistors : 1 /10 W) un-less 

otherwise specified.

  k =1000 , M =1000k .

  % 

: indicates tolerance.

  Caution when replacing chip parts.

  New parts must be attached after removal of chip.
  Be careful not to heat the minus side of tantalum capacitor, because 

it is damaged by the heat.

  Constants of resistors, capacitors, ICs and etc with XX indicate 

that they are not used.

  In such cases, the unused circuits may be indicated.

  All variable and adjustable resistors have characteristic curve B, 

unless otherwise noted.

 

 : nonflammable resistor

 

 : fusible resistor

 

 : panel designation

    f   : internal component.

 : adjustment for repair.
 : B+ Line
 : B– Line

  Circled numbers refer to waveforms.
  Voltages are dc between measurement point.
  Readings are taken with a color-bar signals on Blu-ray disc.
  Readings are taken with a digital multimeter (DC 10M ).
  Voltage variations may be noted due to normal production tolerances.

Note: 
The components identified 
by mark 

  or dotted line 

with mark 

  are critical for 

safety.
Replace only with part num-
ber specified.

Note: 
Les composants identifiés par 
une marque 

  sont critiquens 

pour la sécurité.
Ne les remplacer que par une 
pièce portant le numéro spéci-
fié.

When indicating parts by reference number, please include the 
board name.
