1. General Information 1-1 General Guidelines When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
1) Leakage Current Cold Check 2) Leakage Current Hot Check 3)Prevention of Electro Static Discharge(ESD)to Electrostatically Sensitive
1-2 Important notice 1-2-1. Follow the regulations and warnings Most important thing is to list up the potential hazard or risk for the service personnel to open the units and disassemble the units. For example, we need to describe properly how to avoid the possibility to get electrical shock from the live power supply or charged electrical parts (even the power is off).
This symbol indicates that high voltage is present inside. It is dangerous to make any king of contact with any inside part of this product. This symbol indicates that there are important operating and maintenance instructions in the literture accompanying the appliance
1-2-2. Be careful to the electrical shock To prevent damage which might result in electric shock or fire, do not expose this TV set to rain or excessive moisture. This TV must not be exposed to dripping or splashing water, and objects
Filled with liquid, such as vases, must not be place on top of or above the TV 1-2-3. Electro static discharge (ESD) Some semiconductor (solid state) devices can be damaged easily by static electricity. Such Components commonly are called Electrostatically Sensitive (ES) Devices. The following tech-niquesshouldbeusedtohelpreducetheincidenceofcomponentdamagecausedbyelectro Static discharge (ESD). 1-2-4. About lead free solder (PbF) This product is manufactured using lead-free solder as a part of a movement within the consum-er products industry at large to be environmentally responsible. Lead-free solder must be used in the servicing and repair of this product. 1-2-5. Use the genewing parts (specified parts) Special parts which have purposes of fire retardant (resistors),high-quality sound (capacitors), low noise(resistors), etc. are used. When replacing any of components, be sure to use only manufacture's specified parts shown in the parts list.
Safety Component ● Components identified by mark have special characteristics important for safety.
1-2-6. Safety Check after Repairment Confirm that the screws ,parts and wiring which were removed in order to service are put in the
original positions, or whether there are the portions which are deteriorated around the serviced
places serviced or not. Check the insulation between the antenna terminal or external metal and
the AC cord plug blades. And be sure the safety of that.
Insuration Test 1. Unplug the plug from the AC outlet.
2. Remove the antenna terminal on TV and turn on the TV. 3. Insulation resistance between the cord plug terminals and the eternal exposure metal
should be more than M ohm by using the 500V insulation resistance meter
4. If the insulation resistance is less than M ohm, the inspection repair should be required. If you have not the 500V insulation resistance meter, use a Tester. External exposure metal: Antenna terminal Headphone jack
1-2-7. Ordering Spare Parts Please include the following informations when you order parts. (Particularly the Version letter) 1. Model number and Version letter

External Equipment
Choose Y
To avoid picture noise (interference), leave an adequate distance between the VCR and TV.
Connection Option 1Set VCR output switch to channel 3 or 4 and then tune the TV to the same channel number.
Connection Option 21. Connect the audio and video cables from the VCR's output jacks to the TV input jacks, as shown in the figure.When connecting the TV to VCR, match the jack colors (Video = yellow, Audio Left = white, and Audio Right = red).If you connect a S-VIDEO output from VCR to the S-VIDEO input, the picture quality is improved; compared to connecting a regular VCR to the Video input.
2. Insert a video tape into the VCR and press PLAY on the VCR. (Refer to the VCR owner`s manual.)
3. Select the input source with using theINPUT button on the remote control, and then press / button to select the source,press ENTER button to confirm.

How to connect1. To get the best picture quality, adjust the VGA graphics card to 1024x768 .2. Use the TV`s VGA or DVI (Digital Visual Interface)Audio IN port for audio connections, depending on your computer connector.
If the graphic card on the computer does not output analog and digital RGB simultaneously, connect only one of either VGA IN or HDMI IN to display the VGA on the TV.
If the graphic card on the computer does output analog and digital RGB simultaneously, set the TV to either VGA or HDMI ; (the other mode is set to Plug and Play automatically by the TV.)3. Then, make the corresponding audio connection. If using a sound card, adjust the VGA sound as required.
How to use1. Turn on the computer and the TV.2. Use INPUT on the remote control to select VGA or HDMI source.3. Check the image on your TV. There may be noise associated with the resolution, vertical pattern, contrast or brightness in VGA mode. If noise is present, change the VGA mode to another resolution, change the refresh rate to another rate or adjust the brightness and contrast on the menu until the picture is clear. If the refresh rate of the VGA graphic card can not be changed, change the VGA graphic card or consult the manufacturer of the VGA graphic card.
Note1.Use a DVI cable.2.Avoid keeping a fixed image on the TV's screen for a long period of time. The fixed image may become permanently imprinted on the screen. 3. The synchronization input form for Horizontal and Vertical frequencies is separate.
