SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET
BEFORE REPLACING PARTS.
2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARD-
ED AS POTENTIAL SHOCK HAZARDS WHEN THE
CHASSIS IS OPERATING.
NOTES:
t. The unit of resistance ‘ohm is omitted {k - 1000 ohm,
_ M = Tt Meg ohm.
2. All resistors are 1/8 watt, unless otherwise noted.
3. The unit of capacitance "'F"’ is omitted ty = pF, p = ypF).
4. The values in parentheses are the ones in the PB mode;
the values without parentheses are the ones in the REC
mode.
VOL TAGE MEASUREMENT CONDITIONS:
1. DC voltages are measured between points indicated and
chassis ground by VTVM, with AC100V~240V, 50/60Hz
supplied to unit and all controls are set to normal viewing
picture unless otherwise noted.
. Voltages are measured with 10000.V 8 & W or colour
signal.
WAVEFORM MEASUREMENT CONDITIONS:
10000uV 87.5 percent modulated colour ber signal is fed
