DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACING PARTS. 2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING.
NOTES:
1. The unit of resistance "ohm" is omitted. (K = 1000 ohms, M = Mega ohm). 2. All resistors are 1/10 watt, unless otherwise noted. 3. All capacitors are µF, unless otherwise noted. (P = µµF).
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH " å " ( ) ARE IMPOTANT FOR MAINTAINING THE SAFETY OF THE SET. BE SURE TO REPLACE THESE PARTS WITH SPECIFIED ONES FOR MAINTAINING THE SAFETY AND PERFORMANCE OF THE SET.
VOLTAGE MEASUREMENT CONDITIONS:
1. Voltages in parenthesis measured with no signal. 2. Voltages without parenthesis measured with 3mV B & W or Colour signal. 3. All the voltages in each point are measured with VTVM.
SERVICE PRECAUTION:
THE AREA ENCLOSED BY THIS LINE ( �� - �� ) IS DIRECTLY CONNECTED WITH AC MAINS VOLTAGE. WHEN SERVICING THE AREA, CONNECT AN ISOLATING TRANSFORMER BETWEEN TV RECEIVER AND AC LINE TO ELIMINATE HAZARD OF ELECTRIC SHOCK.
WAVEFORM MEASUREMENT CONDITIONS:
1. The colour bar generator signal of 2.0V peak applied at of Base Video Buffer Amp. Q252. 2. Approximately 4V AGC bias .
