6-3. Printed Wiring Boards and Schematic Diagrams

Note:

All capacitors are in μF unless otherwise noted. pF: μμF 50WV or less are not indicated except for electrolytic and tantalums.

All electrolytics are 50V unless otherwise specified

Indication of resistance, which does not have one for rating electrical power, is as follows:

Pitch: 5mm

Rating electrical power 1/4W

All resistors are in ohms.

KΩ=1000Ω, MΩ=1000KΩ

f nonflammable resistor.

Δ: internal component.

p: panel designation and adjustment for repair.

All variable and adjustable resistors have charac- teristic curve B, unless otherwise noted.

The components identified by ] in this manual have been carefully factory-selected for each set in order to satisfy regulations regarding X-ray radiation. Should replacement be required, replace only with the value originally used.

When replacing components identified by ] make the necessary adjustments indicated. If results do not meet the specified value, change the component identified by [ and repeat the adjustment until the specified value is achieved.

(Refer to R584 on page 27 and 28).

When replacing parts in the table below be sure to perform the related adjustment.

CONFIRMATION

 

 

All voltages are in V.

Voltage is DC with respect to ground unless otherwise noted.

Readings are taken with a 10MΩ digital multimeter.

Readings are taken with a color-bar signal input.

Voltage variations may be noted due to normal produc- tion tolerance.

Circled numbers are waveform references.
