Special note : Most semiconductor devices are electrostatically sensitive and therefore require the special handling techniques described under the "electrostatically sensitive (ES) devices" section of this service manual. Note : Do not use the part number shown on this drawing for ordering. The correct part number is shown in the parts list (may be slightly different or amended since this drawing was prepared). Important safety notices : Components identified with the mark Use only the same type. have the special characteristics for safety. When replacing any of these components.

IMPORTANT SERVICE GUIDE MODE SWITCH (PROGRAM SWITCH) ASSEMBLY POINT 1) When installing the ass'y full deck on the Main PCB, be sure to align the assembly point of mode switch. ASSEMBLY POINT Fig. 1 HOW TO EJECT THE CASSETTE TAPE (If the unit does not operate on condition that tape is inserted into housing ass'y) 1) Remove the Holder Worm OE and the gear worm ґ. (See Fig. 2) 2) Turn the Gear Worm Wheel counterclockwise in the direction of arrow with screw driver. (See Fig. 2) 3) When Slider S, T are approached in the position of unloading, rotate holder Clutch counterclockwise after inserting screw driver in the hole of frame's bottom in order to wind the unwounded tape. (Refer to Fig. 3) (If you rotate Gear Worm Wheel continuously when tape is in state of unwinding, you may cause a tape contamination by grease and tape damage. Be sure to wind the unwounded tape in the state of set horizontally.) 4) Rotate Gear Worm Wheel counterclockwise using screw driver again up to the state of eject mode and then pick out the tape. (Refer to Fig. 2) GEAR WORM WHEEL SCREW DRIVER FRAME ґ GEAR WORM OE HOLDER WORM Fig. 2 Fig. 3 1. Precautions 1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields. 2. When reinstalling the chassis and its assemblies, be sure to restore all pretective devices, including : control knobs and compartment covers. 3. Make sure that there are no cabinet openings through which people--particularly children --might insert fingers and contact dangerous voltages. Such openings include the spacing between the picture tube and the cabinet mask, excessively wide cabinet ventilation slots, and improperly fitted back covers. If the measured resistance is less than 1.0 megohm or greater than 5.2 megohms, an abnormality exists that must be corrected before the unit is returned to the customer. 4. Leakage Current Hot Check (See Fig. 1-1) : Warning : Do not use an isolation transformer during this test. Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI C101.1, Leakage Current for Appliances), and Underwriters Laboratories (UL Publication UL1410, 59.7). 5. With the unit completely reassembled, plug the AC line cord directly the power outlet. With the unit's AC switch first in the ON position and then OFF, measure the current between a known erath ground (metal water pipe, conduit, etc.) and all exposed metal parts, including : antennas, handle brackets, metal cabinets, screwheads and control shafts. The current measured should not exceed 0.5 milliamp. Reverse the power-plug prongs in the AC outlet and repeat the test. 6. Antenna Cold Check : With the unit's AC plug disconnected from the AC source, connect an electrical jumper across the two AC prongs. Connect one lead of the ohmmeter to an AC prong. Connect the other lead to the coaxial connector. 7. Some semiconductor ("solid state") devices are easily damaged by static elect

2. Alignment and Adjustment 2-1 Reference 1) X-Point (Tracking center) adjustment, "Head switching adjustment" and "NVRAM option setting" can be adjusted with remote control. 2) When replacing the Micom (IC601) and NVRAM (IC605 ; EEPROM) be sure to adjust the "Head switching adjustment" and "NVRAM option setting". 3) When replacing the cylinder ass'y, be sure to adjust the "X-Point" and "Head switching adjustment". 4) Among Samsung VCR remote control used for adjustment as a accessory, only the remote control that has figures buttons (0 ~ 9) is available for all adjustment regardless of chassis. 5) How to adjustment. - Press the "SW718 (TEST)" button on Main PCB to set the adjustment mode. - If the corresponding adjustment button is pressed, the adjustment is performed automatically. - If the adjustment is completed, be sure to turn the power off. 2-1-1 Location of adjustment button of remote control STANDBY/ON EJECT Q-PRO SHUTTLE IPC X-Point (Tracking Center) Adjustment ("5" Button) CLR/RST V-LOCK DISPLAY F.ADV INPUT REPEAT INDEX MENU TRK PROG NVRAM Option Setting ("MENU" Button) Head Switching Adjustment ("SPEED" Button) C RE TV/VCR AU DI O D EE SP OK POWER DISPLAY CNT.RESET SPEED IIP/S IPC TRK REC REPEAT MENU Remote Control for adjustment is not supplied as a Service Jig.
