Safety Precautions

PERFORM A SAFETY CHECK AFTER SERVICING
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.
(INSULATION CHECK PROCEDURE)
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 [Note 2] should be more than 1M ohm by using the 500V insulation resistance meter [Note 1].
4. If the insulation resistance is less than 1M ohm, the inspection repair should be required.
[Note 1]
If you have not the 500V insulation resistance meter, use a Tester.
[Note 2]

Disassembly Instructions

1. REMOVAL OF ANODE CAP
Read the following NOTED items before starting work.
* After turning the power off there might still be
a potential voltage that is very dangerous. When removing the Anode Cap, make sure to discharge the Anode Cap’s potential voltage.
* Do not use pliers to loosen or tighten the
Anode Cap terminal, this may cause the spring to be damaged.
REMOVAL
1. Follow the steps as follows to discharge the Anode Cap. (Refer to Fig. 1-1.) Connect one end of an Alligator Clip to the metal part of a flat-blade screwdriver and the other end to ground. While holding the plastic part of the insulated screwdriver, touch the support of the Anode with the tip of the screwdriver. A cracking noise will be heard as the voltage is discharged.
2. Flip up the sides of the Rubber Cap in the direction of the arrow and remove one side of the support. (Refer to Fig. 1-2.)
3. After one side is removed, pull in the opposite direction to remove the other.
NOTE
Take care not to damage the Rubber Cap.
INSTALLATION
1. Clean the spot where the cap was located with a small amount of alcohol. (Refer to Fig. 1-3.)
NOTE
Confirm that there is no dirt, dust, etc. at the spot where the cap was located.
2. Arrange the wire of the Anode Cap and make sure the wire is not twisted.
3.Turn over the Rubber Cap. (Refer to Fig. 1-4.)
4. Insert one end of the Anode Support into the anode button, then the other as shown in Fig. 1-5.
5. Confirm that the Support is securely con­nected.
6. Put on the Rubber Cap without moving any parts.
Service Mode List
This unit provided with the following SERVICE MODES so you can repair, examine and adjust easily. To enter the Service Mode, press both set key and remote control key for more than 2 seconds.

3. After the confirmation of using hours, turn off the power.
NOTE FOR THE REPLACING OF MEMORY IC
If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken to ensure correct data settings while making reference to TABLE 1.
Table 1 (2107 NS Only)
NOTE: No need for the setting after INI 10.
Table 1 (2107 R Only)
NOTE: No need for the setting after INI 16 Table 1 (2107 T Only)
NOTE: No need for the setting after INI 10
1. Enter DATA SET mode by setting VOLUME to minimum.
2. Press both VOL. DOWN button on the set and Channel button (6) on the remote control for more than 2 seconds.
3. ADDRESS and DATA should appear as Fig 1.
4. ADDRESS is now selected and should “blink”. Using the SET + or - keys on the remote, step through the ADDRESS until required ADDRESS to be changed is reached.
5. Press ENTER to select DATA. When DATA is selected, it will “blink”.
6. Again, step through the DATA using SET + or
- until required DATA value has been se­lected.
7. Pressing ENTER will take you back to ADDRESS for further selection if necessary.
