DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTES:NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE1. The unit of resistance Oohm� is omitted.
REPLACING PARTS.(K = 1000 ohms, M = Meg ohm).
2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS2. All resistors are 1/16 watt, unless otherwise noted.
POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OP-3. All capacitors are mF, unless therwise noted. (P = mmF).
ERATING.
VOLTAGE MEASUREMENT CONDITIONS:
IMPORTANT SAFETY NOTICE:1. Voltage in parenthesis measured with no Signal.
PARTS MARKED WITH O�� ( ) ARE IMPORTANT FOR2. Voltages without parenthesis measured with PAL Colour-Signal.
MAINTAINING THE SAFETY OF THE SET. BE SURE TO RE-3. All the voltages in each point are measured with high impedence
PLACE THESE PARTS WITH SPECIFIED ONES FOR MAINTAIN-volt-meter.
ING THE SAFETY AND PERFORMANCE OF THE SET.
WAVEFORM MEASUREMENT CONDITIONS:
SERVICE PRECAUTION:1. Colour bar generator signal of 2.0V peak to peak applied at Base
THE AREA ENCLOSED BY THIS LINE ( ) IS DIRECTLYof Video Buffer Amp. Q254.
CONNECTED WITH AC MAINS VOLTAGE.2. Approximately 4.0 V AGC bias.
WHEN SERVICING THE AREA, CONNECT AN ISOLATING TRANS-
FORMER BETWEEN TV RECEIVER AND AC LINE TO ELIMINATE
HAZARD OF ELECTRIC SHOCK.
