Printed Wiring Boards And Schematic Diagrams Information - Sony KLV-26HG2 Service Manual

3-2. 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 specifi ed.
All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating
electrical power, is as follows:
1 / W in resistance, 1 / W and
4 10
: nonfl ammable 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.
Voltages are DC with respect to ground unless otherwise
noted.
Voltage variations may be noted due to normal production
tolerances.
All voltages are in V.
S : Measurement impossibility.
: B+line.
: B-line. (Actual measured value may be
different).
: signal path. (RF)
Circled numbers are waveform references.
The components identifi ed by shading and
only with part number specifi ed.
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 identifi es per un trame et une marque
securite. Ne les remplacer que par une piece portant le numero specifi e.
Le symbole indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
