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. 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. (J= ± 5%, F= ± 1%, D= ± 0.5%) 3. All resistors are 1/16W, unless otherwise noted. 4. All resistors are Carbon type, unless otherwise noted. W : Cement C : Solid S : Oxide Film T : Special N : Metal Coating CAPACITOR 1. All capacitors are µF, unless otherwise noted. (P=pF=µµF). 2. All capacitors are 50V, unless otherwise noted. 3. All capacitors are Ceramic type, unless otherwise noted. (ML): Mylar (TA): Tantalum (PF): Polypro Film (ST): Styrol CAUTION: This circuit diagram is original one, therefore there may be a slight difference from yours. IMPORTANT SAFETY NOTICE: PARTS MARKED WITH "е" ( ) ARE IMPORTANT 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. 32 LC-20SH1E SCHEMATIC DIAGRAM Л INVERTER Unit H G F E D C B A 1 2 3 4 5 6 33 LC-20SH1E Л SUB Unit-1/2 H G F E D C B A 1 2 3 4 5 6 7 8 9 10 34 LC-20SH1E 10 11 12 13 14 15 16 17 18 19 35 LC-20SH1E Л SUB Unit-2/2 H G F E D C B A 1 2 3 4 5 6 7 8 9 10 36 LC-20SH1E 10 11 12 13 14 15 16 17 18 19 37 LC-20SH1E Л MAIN Unit-1/3 H G F E D C B A 1 2 3 4 5 6 7 8 9 10 38 LC-20SH1E 10 11 12 13 14 15 16 17 18 19 39 LC-20SH1E Л MAIN Unit-2/3 H G F E
