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.

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.DMRF-TUREGULATORSREGULATORSCPUAUDIO_CTRLFBTFOCUS SCREENASSY,PWB,SOCKET ASSY,PWB,VMASSY,PWB,P/D (Power & Deflection)ASSY,PWB,MAINASSY,PWB,FRONT(247 X 330)(247 X 330)ASSY,PWB,VIDEOASSY,PWB,AV(140 X 123.5) (90 X 123.5)+-+-SP-LSP-R(5W,6X12)DEGAUSSING COIL(FOR SPARK)K5DMA10 411 512 6789 123K5DMB1041151261371481591617181920123K5DMC10 411 512 6789 123KF1 1234105116127138914151516171819KG1 1234105116127138914151516171819K8VDB1041151261371481591617181920123K8VDA1041151261371481591617181920123K6PDB1 123456789101112 12K6PDD12345K6PDA1 12345678910 10K9FRA12345678K9FRB123456K25A11234567891010K25VM11233K6A1 12345678910 10K4D12345K5B1 123456789101112 12K6J1 1234 4K4C123XKX1234K7C 123XK7U1K7D11234567891010K17J112344K17A1 12 2K17VM1 123 3XK6L 12K6B 123XK6F12XK6M123XW601XA1XA2K1901123456K190212345678VM_COILDY_COILSP901SP902K1903112344XK190412 L901XKCRTXKSPG2XKSPG1XK6GNDKMLR1112344KSLR212345KMLR2112344KSLR112345XKFRONTXKFRONT2P01P02P04P04 P04P03P03Y(3)Composite Video(1)C(2)R(4)G(5)B(6)R (CRT)(10)G (CRT)(11)B (CRT)(12)Heater(13)H-Drive (Base)(14)H-Drive (Collector)(15)H-OUT (Base)(16)H-OUT (Collector)(17)V-OUT(18)PCC(19)V-Drive (+) Out(7)V-Drive Out(8)V PUMP(9)B-Y(20)R-Y(21)WH OUT(22)WV OUT(23)2Y (Lower)(26)2(B-Y) (Lower)(27)2(R-Y) (Lower)(28) VM (Velocity Modulation)(29)2H (Lower)(24)2V (Lower)(25)SCHEMATICWAVEFORMSBOARD CONNECTIONSAND LOCATIONS
