NOTES ON SCHEMATIC DIAGRAM
1. PRODUCT SAFETY NOTICE
COMPONENTS DESIGNATED BY A MARK (
THE
GRAM DESIGNATE COMPONENTS WHOSE VALUES ARE OF SPECIAL
SIGNIFICANCE TO PRODUCT SAFETY. SHOULD ANY COMPONENT DESIGNATED BY
A MARK NEED TO BE REPLACED, USE ONLY THE PART DESIGNATED IN THE PARTS
LIST. DO NOT DEVIATE FROM THE RESISTANCE, WATTAGE AND VOLTAGE RATINGS
SHOWN.
2. NOTES ON SCHEMATIC DIAGRAM
Specification of capacitor and resistors will be shown with coded symbols, reading code symbols following the chart and
notes. Some capacitor and resistors will be shown directly with values and no other information. Detailed information on
each capacitor and resistor will be shown in the list.
NOTE; DO NOT REPLACE OR ORDER RESISTOR AND CAPACITOR PARTS FOLLOWING THE SPECIFICATIONS
SHOWN IN THE SCHEMATIC DIAGRAMS.
ALWAYS CHECK FOR THE CORRECT SPECIFICATIONS IN THE PARTS LIST. ESPECIALLY FOR CRITICAL COM-
PONENT MARKED
3. READING IN SCHEMATIC DIAGRAM
Read resistor codes as follows:
1. All resistance values are indicated in ohms: K=1,000. M=1,000,000.
2. Resistor which is indicated with resistance value only are 1/6W carbon resistor. Resistor which is indicated with material
tolerance and value are 1/4W rated wattage.
Read capacitor codes as follows:
1. For capacitors identified with
2. For capacitors (electrolytic) identified with
Voltage and waveforms were taken using a video color bar signal (1V p-p at 75 ohms terminated) and controls to nor-
mal.
Voltages were taken with a high-impedance voltmeter.
4. SERVICE NOTES;
1. When replacing high wattage resistors on circuit board, keep the resistor body 10 mm (3/8") from circuit board.
2. Keep wires away from high voltage and high temperature components.
. SPECIAL ATTENTION MUST BE GIVEN TO CRITICAL COMPONENTS.
, values less than 1 are expressed in uF, values more than 1 are in pF.
, values are expressed in uF.
