DESCRIPTION OF SCHEMATIC DIAGRAM
[1] DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE
REPLACING PART.
2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS
POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS
OPERATING.
IMPORTANTS SAFETY NOTICE:
PARTS MARKED WITH " " ( ) ARE IMPORTANT FOR
MAINTAINING THE SAFETY OF THR SET. BE SURE TO REPLACE
THESE PARTS WITH SPECIFIED ONES FOR MAINTAINING THE
SAFETY AND PERFORMANCE OF THE SET.
SERVICE PRCUATION:
THE AREA ENCLOSED BY THIS LINE ( ) IS DIRECTLY
CONNECTED WITH AC MAINS VOLTAGE.
WHEN SERVICING THE AREA CONNECT AN ISOLATING
TRANSFORMER BETWEEN TV RECEIVER AN AC LINE TO
ELIMINATE HAZARD OF ELECTRIC SHOCK.
NOTES:
1. The unit od resistance "ohm" is omitted.
(K = 1000 ohms, M = Meg ohm).
2. All resistor are 1/16 watt, unless otherwise noted.
3. All capacitors are µF, unless otherwise noted. (P = µµF).
VOLTAGE MESUREMENT CONDITIONS:
1. Voltages in parenthesis measured with no Signal.
2. Voltages without parenthesis measured with PAL
Colour-Signal.
3. All the voltages in each point are measured high
impedance volt-meter.
WAVEFORM MEASUREMENT CONDITIONS:
1. RF colour bar signal of 2.0V peak to peak applied at
RF Tuner TU51.
2. Approximately 4.0V AGC bias (without signal).
