When replacing parts on circuit boards, clamp the lead wires to terminals before soldering.2. When replacing high wattage resistors on circuit board, keep the resistor body 10 mm (3/8) from circuit board.3. Keep wires away from high voltage and high temperature components.PRODUCT SAFETY NOTICETHE COMPONENTS DESIGNATED BY A STAR () ON THIS SCHEMATIC DIAGRAM DESIGNATE COMPONENTSWHOSE VALUES ARE OF SPECIAL SIGNIFICANCE TO PRODUCT SAFETY. SHOULD ANY COMPONENTDESIGNATED BY A STAR NEED TO BE REPLACED, USE ONLY THE PART DESIGNATED IN THE PARTS LIST. DO NOTDEVIATE FROM THE RESISTANCE, WATTAGE AND VOLTAGE RATINGS SHOWN.X-RADIATION WARNING NOTETHIS TV CONTAINS CRITICAL PARTS TO PROTECT AGAINST X-RADIATION.

Unless otherwise noted on schematic, all capacitor values less than 1 are expressed in μF (Micro Farad),and the values more than 1 are in pF.3. Unless otherwise noted on schematic, voltage reading taken with VOM from point indicated to chassisground. Voltage reading taken using color-bar signal VHF channel 5, all controls at normal. Line voltage at 120volts. Some voltages may vary with signal strength.4. Waveforms were taken with color-bar signal and controls set for normal picture. Waveforms marked withan ✽ may vary with signal strength.5. The Symbol indicates a fusible resistor, which protects the circuit from possible short circuits.Device/Pin # Volts/ModeIC101-36 5.0IC101-37 4.3IC101-38 4.7IC101-39 GNDIC101-40 0IC101-41 GNDIC101-42 GNDIC101-43 GNDIC101-44 2.3IC101-45 3.6IC101-46 2.1IC101-47 3.1IC101-48 GNDIC101-49 2.5IC101-50 GNDIC101-51 GNDIC101-52 2.6IC101-53 5.1IC101-54 2.9IC101-55 2.6IC101-56 2.5IC101-57 GNDIC101-58 3.6IC101-59 4.4IC101-60 4.4IC101-61 GNDIC101-62 GNDIC101-63 GNDIC101-64 GNDIC101-65 2.4IC101-66 2.2IC101-67 2.2IC101-68 2.4IC101-69 3.2IC101-70 GNDIC101-71 GNDIC101-72 GNDIC101-73 2.3IC101-74 GNDIC101-75 2.2IC101-76 2.6IC101-77 2.2IC101-78 2.9IC101-79 2.9IC101-80 GNDIC501-1 2.5IC501-2 25.9IC501-3 2.9IC501-4 GNDIC501-5 18.0IC501-6 26.5IC501-7 2.6IC601-1 130.0IC601-2 24.8IC601-3 GNDIC681-1 13.4IC681-2 GNDIC681-3 5.0IC801-1 4.0IC801-2 4.9IC801-3 4.9IC801-4 0IC801-5 0IC801-6 0.3IC801-7 0IC801-8 0IC801-9 0IC801-10 4.9IC801-11 GNDIC801-12 4.8IC801-13 GNDIC801-14 4.9IC801-15 1.9IC801-16 0.2IC801-17 2.1IC801-18 GNDIC801-19 2.2IC801-20 2.0IC801-21 GNDIC801-22 4.9IC801-23 GNDIC801-24 GNDIC801-25 4.9IC801-26 0.3POWER ON: POWER OFF:IC801-27 4.9 0IC801-28 2.4IC801-29 2.8IC801-30 0IC801-31 4.9IC801-32 3.6IC801-33 4.9IC801-34 3.7IC801-35 4.8IC801-36 4.9Device/Pin # Volts/ModePOWER ON: POWER OFF:D612-1 25.7 9.6POWER ON: POWER OFF:D612-2 24.8 8.0POWER ON: POWER OFF:D612-3 0.7 0.4POWER ON: POWER OFF:D612-4 14.7 1.7IC001-1 6.7IC001-2 15.4IC001-3 N.C.IC001-4 GNDIC001-5 N.C.IC001-6 1.4IC001-7 1.4IC001-8 GNDIC101-1 GNDIC101-2 GNDIC101-3 GNDIC101-4 GNDIC101-5 GNDIC101-6 5.1IC101-7 2.1IC101-8 2.7IC101-9 3.8IC101-10 3.6IC101-11 4.3IC101-12 1.5IC101-13 1.5IC101-14 1.4IC101-15 0.2IC101-16 8.2IC101-17 2.5IC101-18 2.2IC101-19 2.4IC101-20 GNDIC101-21 GNDIC101-22 GNDIC101-23 GNDIC101-24 GNDIC101-25 N.C.IC101-26 2.1IC101-27 2.6IC101-28 5.3IC101-29 2.7IC101-30 0.4IC101-31 GNDIC101-32 N.C.IC101-33 1.0IC101-34 1.8IC101-35 N.C.Device/Pin # Volts/ModeQ486-B 9.9Q486-C 11.6Q486-E 9.2Q490-B 5.9Q490-C 6.7Q490-E 5.2POWER ON: POWER OFF:Q601-G 5.8 0.4POWER ON: POWER OFF:Q601-D 157 164POWER ON: POWER OFF:Q601-S 15 0POWER ON: POWER OFF:Q613-B 0.2 0.1POWER ON: POWER OFF:Q613-C 4.7 0.1Q613-E GNDPOWER ON: POWER OFF:Q627-B 12.7 8.0POWER ON: POWER OFF:Q627-C 13.2 0POWER ON: POWER OFF:Q627-E 13.3 8.0POWER ON: POWER OFF:Q635-B 3.4 1.3POWER ON: POWER OFF:Q635-C 25.0 8.2POWER ON: POWER OFF:Q635-E 3.4 1.1POWER ON: POWER OFF:Q681-B 0.7 0POWER ON: POWER OFF:Q681-C 0 6.0Q681-E GNDPOWER ON: POWER OFF:Q693-B 0.5 5.2POWER ON: POWER OFF:Q693-C 24.7 7.1POWER ON: POWER OFF:Q693-E 0.6 4.7POWER ON: POWER OFF:Q695-B 24.7 7.4Q695-C GNDPOWER ON: POWER OFF:Q695-E 24.8 8.0Q701-B 2.4Q701-C 154.9Q701-E 2.2IC801-37 4.9IC801-38 4.8IC801-39 0.2IC801-40 0IC801-41 0IC801-42 0IC802-1 GNDIC802-2 GNDIC802-3 GNDIC802-4 GNDIC802-5 4.9IC802-6 4.9IC802-7 GNDIC802-8 5.0IC1081-1 2.5IC1081-2 2.9IC1081-3 2.5IC1081-4 2,4IC1081-5 2.4IC1081-6 GNDIC1081-7 GNDIC1081-8 GNDIC1081-9 0IC1081-10 0IC1081-11 0IC1081-12 2.9IC1081-13 2.5IC1081-14 2.9IC1081-15 2.9IC1081-16 9.3IC3401-1 4.1IC3401-2 4.1IC3401-3 4.1IC3401-4 4.1IC3401-5 3.6IC3401-6 3.7IC3401-7 GNDIC3401-8 4.1IC3401-9 4.1IC3401-10 4.1IC3401-11 4.1IC3401-12 4.9IC3401-13 4.1IC3401-14 1.3IC3401-15 1.3IC3401-16 0IC3401-17 GNDIC3401-18 3.2IC3401-19 9.1IC3401-20 0IC3401-21 4.1Device/Pin # Volts/Mode Device/Pin # Volts/ModeIC3401-22 4.1IC3401-23 3.7IC3401-24 3.9IC3401-25 4.1IC3401-26 4.1IC3401-27 4.1IC3401-28 1.9IC3401-29 4.1IC3401-30 4.1IC3401-31 2.0IC3401-32 4.1IC3401-33 4.1IC3401-34 4.1IC3401-35 0IC3401-36 4.1IC3401-37 4.1IC3401-38 4.1IC3401-39 4.1IC3401-40 4.1IC3401-41 4.1IC3401-42 GNDIC3401-43 4.1IC3401-44 4.1IC3401-45 4.2IC3401-46 GNDIC3401-47 4.1IC3401-48 4.1POWER ON: POWER OFF:Q001-B 0.7 0POWER ON: POWER OFF:Q001-C 0 17.0Q001-E GNDQ005-B 15.4Q005-C 16.0Q005-E 16.1Q135-B 2.2Q135-C 5.0Q135-E 1.5Q202-B 1.7Q202-C GNDQ202-E 2.3Q208-B 2.5Q208-C GNDQ208-E 3.1Q401-B 0.3Q401-C 17.7Q401-E GNDQ402-B 3.2Q402-C N/AQ402-E 3.2Device/Pin # Volts/Mode Device/Pin # Volts/Mode |
