3 Alignments and Adjustments 3 Alignments and Adjustments 3-1 Service Instruction 1. Usually, a color TV-VCR needs only slight touch-up adjustment upon installation. Check the basic characteristics such as height, horizontal and vertical sync. 2. Use the specified test equipment or its equivalent. 3. Correct impedance matching is essential. 4. Avoid overload. Excessive signal from a sweep generator might overload the front-end of the TV. When inserting signal markers, do not allow the marker generator to distort test result. 5. Connect the TV only to an AC power source with voltage and frequency as specified on the backcover nameplate. 6. Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts. 7. To protect aganist shock hazard, use an isolation transform. 3-1 3 Alignments and Adjustments 3-2 How to Access Service Mode 3-2-1 Entering Factory Mode 1.

Connecting an Aerial or Cable Television Network To view television channels correctly, a signal must be received by the set from one of the following sources: - An outdoor aerial / A cable television network / A satellite network 2. Connecting HDMI/DVI - Supports connections between HDMI-connection-enabled AV devices (Set-Top Boxes, DVD players, AV receivers and digital TVs). - No sound connection is needed for an HDMI to HDMI connection. What is HDMI? - HDMI, or high-definition multimedia interface, is a next-generation interface that enables the transmission of digital audio and video signals using a single cable without compression. - "Multimedia interface" is a more accurate name for it especially because it allows multiple channels of digital audio(5.1 channels).The difference between HDMI and DVI is that the HDMI device is smaller in size, has the HDCP(High Bandwidth Digital Copy Protection) coding feature installed, and supports multi - channel digital audio. - Use the HDMI/DVI terminal for DVI connection to an extended device. You should use the DVI-to-HDMI cable or DVI-HDMI Adapter for the connection, and the "R - AUDIO - L" terminal on DVI for sound output. 3. Connecting Set-Top Box, VCR or DVD - Connect the VCR or DVD SCART cable to the SCART connector of the VCR or DVD. - If you wish to connect both the Set-Top Box and VCR (or DVD), you should connect the Set-Top Box to the VCR (or DVD) and connect the VCR (or DVD) to your set. 5. Connecting External A/V Devices - Connect RCA or S-VIDEO cable to an appropriate external A/V device such as VCR, DVD or Camcorder. - Connect RCA audio cables to "R - AUDIO - L" on the rear of your set and the other ends to corresponding audio out connectors on the A/V device. - Headphone may be connected to the headphone output ( 4 ) on the rear of your set. While the headphone is connected, the sound from the built-in speakers will be disabled. 6. SERVICE - Connector for engin

1 Precautions 1 Precautions Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock. 1-1 Safety Precautions 1-1-1 Warnings 1. 2. For continued safety, do not attempt to modify the circuit board. Disconnect the AC power and DC Power Jack before servicing. 1-1-2 Servicing the LCD Monitor 1. 2. When servicing the LCD Monitor Disconnect the AC line cord from the AC outlet. It is essential that service technicians have an accurate voltage meter available at all times. Check the calibration of this meter periodically. 1-1-3 Fire and Shock Hazard Before returning the monitor to the user, perform the following safety checks: 1. Inspect each lead dress to make certain that the leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the monitor. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc. Leakage Current Hot Check (Figure 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). Figure 1-1. Leakage Current Test Circuit 1-1-4 Product Safety Notices Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual inspection. The protection they give may not be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by on schematics and parts lists. A substitute replacement that does not have the same safety characteristics as the recommended replacement part might create shock, fire and/or other hazards. Product safety is under review continuously and new instructions are issued whenever appropriate. 2. 3. 1-1 1 Precautions 1-2 Servicing Precautions WARNING: Caution: Note: An electrolytic capacitor installed with the wrong polarity might explode. Before servicing units covered by this service manual, read and follow the Safety Precautions section of this manual. If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precautions. 1-2-1 General Servicing Precautions 1. Always unplug the unit s AC power cord from the AC power source and disconnect the DC Power Jack before attempting to: (a) remove or reinstall any component or assembly, (b) disconnect PCB plugs or connectors, (c) connect a test component in parallel with an electrolytic capacitor. Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used. The internal wiring is sometimes clamped to p
