1. Precaution

1. Precaution Follow these safety instructions while servicing the ESD to prevent damage and to protect against potential hazards such as electrical shock and X-rays.

1.1. Safety Precautions 1) When reinstalling the chassis and its assemblies, be sure to restore all of the protective devices, including the control knobs and the compartment covers. 2) Make sure that there are no cabinet openings through which people (particularly children) can make contact with dangerous internal components. 3) Design Alteration Warning: Never alter or add to the mechanical or electrical design of the unit. Example: Do not add auxiliary audio or video connectors. Such alterations might create a safety hazard. Also, any design changes or additions will void the manufacturer’s warranty. 4) Leakage Current Hot Check Figure 1.1 AC Leakage Test: 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).

With the unit completely reassembled, plug the AC cord directly into a 120V AC outlet. With the unit’s power switched from the ON to the OFF position, measure the current between a known ground and all exposed metal parts. Known Grounds - Earth Known Metal parts - screwheads, metal cabinets, etc.

1. Precaution

5) Insulation Resistance Cold Check: (1) With the unit’s AC plug disconnected from the AC source, connect an electrical jumper across the two AC prongs. (2) Set the power switch to ON. (3) Measure the resistance between the shorted AC plug and any exposed metallic parts. Example: screwheads, metal cabinets, antenna port, etc. If any of the exposed metallic parts has a return path to the chassis, the measured resistance should be between 1 and 5.2 megohms. If there is no return path, the measured resistance should be “infinite.” If the resistance is outside these limits, a shock hazard might exist. See Figure 1.2 Insulation Resistance Test

Expo s ed Meta l P a rt oh m Ohmmet er

Figure 1.2 Insulation Resistance Test

6) Components, parts and wiring that appear to have overheated or that are otherwise damaged should be replaced with parts that meet the original specifications. Always determine the cause of damage or overheating, and correct any potential hazards. 7) Observe the original lead dress, especially near the following areas: Antenna wiring, sharp edges, and especially the AC and high voltage power supplies. Always inspect for pinched, out-of-place, or frayed wiring. Do not change the spacing between components and the printed circuit board. Check the AC power cord for damage. Make sure that no wires or components touch thermally hot parts. 8) Product Safety Notice: Some electrical and mechanical parts have special safety-related characteristics which might not be obvious from visual inspection. These safety features and the protection they give might be lost if the replacement component differs from the original—even if the replacement is rated for higher voltage, wattage, etc. 9) Components that are critical for safety are indicated in the circuit diagram by shading, or . Use replacement components that have the same ratings, especially for flame resistance and dielectric strength specifications. A replacement part that does not have the same safety characteristics as the original might create shock, fire or other hazards.

1. Precaution

1.2. Servicing Precautions 1) Servicing precautions are printed on the cabinet. Follow them. 2) Always unplug the unit’s AC power cord from the AC power source before attempting to: (a) Remove or reinstall any component or assembly, (b) Disconnect an electrical plug or connector, (c) Connect a test component in parallel with an electrolytic capacitor. 3) Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used. The internal wiring may be clamped to prevent contact with thermally hot components. Reinstall all such elements to their original position. 4) After servicing, always check that the screws, components and wiring have been correctly reinstalled. Make sure that the portion around the serviced part has not been damaged. 5) Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels, input terminals and earphone jacks). 6) Insulation Checking Procedure: Disconnect the power cord from the AC source. Connect an insulation resistance meter (500V) to the blades of the AC plug. The insulation resistance between each blade of the AC plug and accessible conductive parts (see above) should be greater than 1 megohm. 7) Never defeat any of the B+ voltage interlocks. Do not apply AC power to the unit (or any of its assemblies) unless all solid-state heat sinks are correctly installed. 8) Always connect a test instrument’s ground lead to the instrument chassis ground before connecting the positive lead; always remove the instrument’s ground lead last. CAUTION First read the “Safety Precautions” section of this manual. If some unforeseen circumstance creates a conflict between the servicing and safety precautions, always follow the safety precautions.

1. Precaution

1.3. Precautions for Electrostatically Sensitive Devices (ESDs) Some semiconductor (“solid state”) devices are easily damaged by static electricity. Such components are called Electrostatically Sensitive Devices (ESDs). Examples include integrated circuits and some field-effect transistors. The following techniques will reduce the occurrence of component damage caused by static electricity: 1) Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground. Alternatively, wear a discharging wrist-strap device. (Be sure to remove it prior to applying power–this is an electric shock precaution.) 2) After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to prevent accumulation of electrostatic charge. 3) Do not use freon-propelled chemicals. These can generate electrical charges that damage ESDs. 4) Use only a grounded-tip soldering iron when soldering or unsoldering ESDs. 5) Use only an anti-static solder removal device. Many solder removal devices are not rated as “anti-static” (these can accumulate sufficient electrical charge to damage ESDs). 6) Do not remove a replacement ESD from its protective package until you are ready to install it. Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam, aluminum foil or other conductive materials. 7) Immediately before removing the protective material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed. 8) Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together, or lifting a foot from a carpeted floor can generate enough static electricity to damage an ESD.

4.3. MICOM, MPEG Initialization & Update ■ Micom Reset

• During STANDBY mode, push the “STOP” button 5 Second. If VFD blinking, reset is finished. ■ Micom Update (Only for Flash Micom)

• Method 1) MAIN PCB UTCN1 for update JIG. To update Micom, it need Computer, Rom Writer, USB Cables. • Method 2) Insert USB Memory, and play. “Updating” will be displayed. Set will be power off when finish. ■ Micom & MPEG Version Check 1) Power On. 2) CD open status. 3) Push the number NEXT for 5 seconds, check the Micom version. 4) Push the number PREVIOUS for 5 seconds, check the MPEG version.

■ MPEG Update Method 1) Prepare Rom file at USB Memory. 2) Insert USB Memory, and play. “Update” will be displayed and glisten. Set will be power off → on. 3) The disc is automatically ejected. (If you use USB memory, detach USB memory.)

■ MPEG Reset

• During “No Disc” displayed, push the stop button 5 seconds. After displayed “INITIALIZE” set will power off automatically.

4.4. Buyer-Region Code Setting Method

4.4.1. The inserting method of Region Code after replacing the Main PBA NOTE •

When replacing the Main PBA and System Micom should be inserted the region code.

•

The set is not working properly if you don't insert the region code.

•

The region code is inserted by the remote control.

1) Press “FUNCTION” button several times to change to AUX mode.

2) Press “ENTER” button more than 5 seconds.

3) After step (2), you can see “TEST − −” on the VFD. Insert number “46” to select Region Code.
