DESCRIPTION OF SCHEMATIC DIAGRAM

SCHEMATIC DIAGRAM

VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on the stable supply voltage of AC 220-240V. Signals are fed by a colour bar signal generator for servicing purpose and the above voltages are measured with a 20k ohm/V tester.

LC-26P50E LC-32P50E LC-37P50E

INDICATION OF RESISTOR & CAPACITOR:
RESISTOR 1. The unit of resistance "�" is omitted. (K=k�=1000 �, M=M�). 2. All resistors are ± 5%, unless otherwise noted. (K= ± 10%, F= ± 1%, D= ± 0.5%) 3. All resistors are 1/16W, unless otherwise noted. CAPACITOR 1. All capacitors are µF, unless otherwise noted. (P=pF=µµF). 2. All capacitors are 50V, unless otherwise noted. CAUTION:
This circuit diagram is original one, therefore there may be a slight difference from yours.

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.
