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.  k
=1000, M=1000k
Indication of resistance, which does not have one for rating 
electrical power, is as follows:

: 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 10M
 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 X in this basic schematic diagram 
have been carefully factory-selected for each set in order to satisfy 
regulations regarding X-ray radiation. Should replacement be 
necessary, replace only with the value originally used.
When replacing components identifi ed by Y, make the necessary 
adjustments as indicated.  If the results do not meet the specifi ed 
value, change the component identifi ed by 
X and repeat the 
adjustment until the specifi ed value is achieved. 
When replacing the parts listed in the table below, it is important to 
perform the related adjustments.

The components identifi ed by shading and 
!
 
symbol are critical for safety. Replace 
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 
!
 sont critiques pour la 
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.
