Printed Wiring Boards And Schematic Diagrams Information - Sony KDL-40NX720 Service Manual

1-2. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS INFORMATION

All capacitors are in µF unless otherwise noted. pF : µµF 50WV
or less are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise specified.
All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating
electrical power, is as follows:
/ W in resistance, / W and

: nonflammable resistor
: fusible resistor
: internal component
: panel designation and adjustment for repair
: earth ground
: earth-chassis
All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
Readings are taken with a color-bar signal input.
Readings are taken with a 10MΩ digital multimeter.

Circled numbers are waveform references.
The components identified by shading and
only with part number specified.
The symbol indicates a fast operating fuse and is displayed on the component
side of the board. Replace only with fuse of the same rating as marked.
Les composants identifies per un trame et une marque
securite. Ne les remplacer que par une piece portant le numero specifie.
Le symbole indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
NOTE: The components identified by a red outline and a mark contain confidential
information. Specific instructions must be adhered to whenever these components
are repaired and/or replaced.
