SCHEMATIC DIAGRAM
SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC
OUTLET BEFORE REPLACiNG PARTS.
2. SEMICONDUCTOR HEAT SINKS SHOULD BE
REGARDED AS POTENT/AL SHOCK HAZARDS
WHEN THE CHASSiS IS OPERATING.
NOTES:
1. The unit of resistance “ohm” is omitted (k =
1000 ohm, M = 1 Meg ohm).
2. Ail resistors are l/8 watt, unless otherwise
no ted.
3. The unit of capacitance 7” is omitted (,u =pF,
P =/+F).
4. The values in parentheses are the ones in the
PB mode; the values without parentheses are
the ones in the REC mode.
VOLTAGE MEASUREMENTCONDiTiONS:
1. DC voltages are measured between points in-
dicated and chassis ground by VTVM, with
AC1 lo-24OV, 50/6OHz supplied to unit and all
controls are set to normal viewing picture un-
less otherwise noted.
2. Voltages are measured with 1OOOOpV B 8 W
or co/our signal.
WAVEFORM MEASUREMENT CONDITIONS:
7OOOOpV 87.5 percent modulated co/our bar sig-
nal is fed into tuner.
CAUTION:
This circuit diagram is original one. Therefore
there may be a slight difference from yours.
