3. Alignment & Adjustment3-1 Service Instruction 1. General Adjustment :

In general, a color TV can provide ideal visual quality by adjusting the basic settings such as the vertical size, horizontal size, focus, etc.Display a black and white picture on the screen to check if the picture is clearly displayed.If there are some 'spotted' points on the screen when displaying a black and white picture, degauss the screen using the degauss coil. If the spotted points remain, re-adjust the purity and the convergence. This completes the basic performance examination.

Notice. These adjustments and the check list are only applied to K62A chassis-applied models. Only use 110V for the measurement set. It is recommended using an insulation transformer when supplying power to

the set so as to prevent shock to the set or to yourself. These adjustment specifications have been created on the basis of the domestic K62A chassis-applied remote control

model. Some of the contents may be changed subject to the sales location and the product specifications.

2. When replacing the System Board :Since the software is loaded to the flash memory of the system board, check the version of the software after replacing the board.To check the version of the software, select Menu-Settings-Function Help-Settings and press the "Information Display" key on the remote control. The software information will then be displayed below the OSD menu.The notation of the software information : For example, T_COREAUS0_0013 refers to

"CORE BASIC MODEL USA. ver0013".Since the settings including the Channel information, Deflection, etc. are saved to the nvRAM, reconfigure these settings when replacing the System Board.

3. When replacing the Deflection Board :Tilt adjustment, focus adjustment, screen voltage setting and W/B adjustment are all required.

4. When replacing the Power Board : No adjustments required.

5. When replacing the CRT Ass'y : No adjustments required.

6. When replacing the front panel master power switch : No adjustments required.

7. When replacing the Side AV : No adjustments required.

8. When replacing the control switch : No adjustments required.

3-5-2 Service Download Procedure

1. Select "Power Off Mute 1 8 2 Power On"to select Service Mode.Check that the Anynet Port is set to Svc.

2. If it is not set to Svc, set it to Svc using the left and right direction keys and turn the TV set off.

3. When the TV set is turned off, connect the serial cable for download to the Svc port of the TV set and the COM port of the computer.

4. Turn the TV set on and check the screen display status. Prepare the download software, sdown.bat, and the image of thecorresponding version of the software on the computer.



Separate the serial cable onlyafter the power LED is turned off.

6. The software is automatically downloaded to the TV.

Notice: Take care when downloading the software, because if the set is turned on while writing the corresponding image data tothe flash memory, the flash memory will be damaged and has to be replaced.

5. While the TV set is on, run sdown.bat.When the percentage of the Reading File becomes 100%, turn the TV set off using the transmitter.

7. When the write operation is complete, disconnect the power cord of the TV set. When the power LED is turned off (after approximately 10 seconds), separate the serial cable from the TV and turn the TV on and check the version of the software.

Notice: If you separate the serial cable from the TV before the power LED is turned off, the COM port of the computer may be damaged. Ensure that the serial cable is not separated from the TV and the computer, until the power LED is turned off.



3-5-3 Checking the System Using HyperTerminal

1. The HyperTerminal setup procedures for using HyperTerminal through a RS-232 connection.

2. Select [Start] -> [All Programs] ->[Accessories]-> [Communications] -> [HyperTerminal]

3. In the New Connection window, enter the name of your choice (e.g.TR2), select an icon for the connection and then click theOK button.

5. Configure the Port Settings in the COM1 Properties window as follows and then click the OK button.Bits per second 115200Data bits 8Parity None Stop bits 1Flow control None

6. Run HyperTerminal.

7. Connect the RS-232 cable to the debug port of the TV set and the COM port of the computer and run the HyperTerminalconnection icon created in the steps above.



3-6 Replacements & Calibration

3-6-1 Adjusting the Focus

Since the K62A chassis has a built-in dynamic focus circuit, take care when adjusting the focus. When the CRT PCB, FBT or CRT has been replaced, the focus has to be adjusted according to the following procedures.

1. Display the CROSS Hatch pattern.

2. Set the Screen Adjustment to "View as Standard".

3. Turn the Static Focus VR clockwise to the maximum position.(End of clockwise direction)

4. Turn the Dynamic Focus VR counter clockwise to the maximum position.(End of counter clockwise direction)

5. Slowly turn the Static Focus VR counter clockwise so that the center vertical lineis the most clearly displayed.

White Balance Standard Data

3-6-4 Check List for the Screen Voltage and White Balance Adjustment

1. The Screen Voltage and White Balance are connected each other, and both of them have to be configured to the correct values.

2. Adjust the White Balance after the Screen Voltage was adjusted, and check if the Screen Voltage is normal after adjusting the White Balance.

3. If the White Balance is readjusted, check the Screen Voltage again.

4. When the adjustment is finished, check the following checklist.- If there is a spot on the screen when turning the TV set off/on, adjust the Screen Voltage again.- If there is a ghost line on the screen, adjust the Screen Voltage again.
