Precautions 1. Precautions Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays. 1-1 Safety 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 protective devices, including: nonmetallic 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 (Figure 1-1): Warning: Do not use an isolation transformer during this test. Use a leakagecurrent tester or a metering system that complies with American National Standards Institute (ANIS 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 into the power outlet. With the unit's AC switch first in the ON position and then OFF, measure the current between a known earth 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 powerplug prongs in the AC outlet and repeat the test. DEVICE UNDER TEST TEST ALL EXPOSED METAL SURFACES 3-WIRE CORD ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) LEAKAGE CURRENT TESTER (READING SHOULD NOT BE ABOVE 0.5mA) EARTH GROUND Fig. 1-1 AC Leakage 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. X-ray Limits: The picture tube is especially designed to prohibit X-ray emissions. To ensure continued X-ray protection, replace the picture tube only with one that is the same type as the original. Carefully reinstall the picture tube shields and mounting hardware; these also provide X-ray protection. 8. High Voltage Limits: High voltage must be measured each time servicing is done on the B+, horizontal deflection or high voltage circuits. Correct operation of the X-ray protection circuits must be reconfirmed whenever they are serviced. (X-ray protection circuits also may be called "horizontal disable" or "hold-down".) Heed the high voltage limits. These include the X­ray Protection Specifications Label, and the Product Safety and X-ray Warning Note on the service data schematic. Samsung

Alignment and Adjustments 4. Alignment and Adjustments 4-1 Adjustments 4-1-1 General Alignment Instructions Usually, a color TV needs only slight touch-up adjustment upon installation. Check the basic characteristics such as vertical size, horizontal size, and focus. Observe the picture and check for good black and white details. There must be no objectionable color shading: If color shading is present, demagnetize the receiver. If color shading persists, re-do purity and convergence adjustments. Note : 1. This `4. Alignment and Adjustments' applies to S57A chassis applications. 2. AC Power Supply: 100~230 V 3. This service manual has been written on the basis of domestic remote-control model adopting S57A chassis. Depending on sales location and product specifications, some of specifications herein may be changed. 4-1-2 Focus Adjustment S57A contains a dynamic focus circuit. When CRT PCB, FBT or CRT is replaced, be sure to adjust in the following sequence: Dynamic Focus Adjustment 1. Input a crosshatch pattern. 2. Select "Standard" from the menu, 3. Turn the Static Focus VR clockwise to set it to its maximum. 4. Turn the Dynamic Focus VR counterclockwise to set it to its maximum. 5. Turn the Static Focus VR counterclockwise slowly for the clearest center vertical line. STATIC FOCUS VR H DYNAMIC FOCUS VR V NO USE After Adjustment 6. Turn the Dynamic Focus VR clockwise slowly for the clearest third line. 1 2 3 7. Check for the FOCUS of entire screen. If necessary, re-do adjustments 3~6. Samsung Electronics 4-1 Alignment and Adjustments 4-1-3 Screen Voltage Adjustment 1. Use a DC multi-meter to identify RK, GK, BK. And then adjust FBT Screen VR so that the highest voltage becomes 175 Vp-p. 4-1-4 White Balance Adjustment 1. Select "Standard" from the menu. 2. Input an 100% White pattern. 3. In standby, press the remote-control keys in the following sequence: Display Menu,Mute, Power on the TV set. 4. Warm up the TV set at least for 30 minutes. 5. Input a stair signal. 6. Use the Volume +/- buttons on the remote-control to select R Drive,G Drive,B Drive,Sub Cont. 7. Adjust Low-Light while viewing the darker side of screen. 8. Use the Volume +/- buttons on the remote-control to select Rcutoff,Gcutoff,Bcutoff,Sub Brt. 9. Adjust High-Light while viewing the brighter side of screen. 10. If not proper, re-adjust White Balance. 11. Press the Memory button to exit. 4-1-5 Sub-Brightness Adjustment 1. In standby, press the remote-control keys in the following sequence: Display Menu Mute Power on the TV set. 2. Use the Channel Up/Down buttons to receive the sub bright adjustment signal. 3. Use the Volume +/- buttons to select SBT. 4. Press the Menu or Mute button on the remote control to adjust so that the seventh step on the right of screen cannot be seen. 5. Press the Memory button to exit. 4-2 Samsung Electronics Alignment and Adjustments 4-2 MICOM PINNING 4-2-1 MICOM PINNING (SDA30C264) P6.2 P6.3 P6.4 P6.5 P6.6 VSYNC HSYN
