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]
External exposure metal:Antenna terminal
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 con-
nected.
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.
CONFIRMATION OF USING HOURS
POWER ON total hours can be checked on the
screen. Total hours are displayed in 16 system
of notation.
1. Set the 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. 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 se-
lected.
7. Pressing ENTER will take you back to
ADDRESS for further selection if necessary.
8. Repeat steps 4 to 7 until all data has been
checked.
9. When satisfied correct DATA has been
entered, turn POWER off (return to STANDBY
MODE) to finish DATA input.
The unit will now have the correct DATA for the
new MEMORY IC.
Electrical Adjustments
1. BEFORE MAKING ELECTRICAL ADJUST-
MENTS
Read and perform these adjustments when
repairing the circuits or replacing electrical parts
or PCB assemblies.
CAUTION
1-1:Prepare the following measurement tools
for electrical adjustments.
1. Synchro Scope
2. Digital Voltmeter
3. Color Bar Generator
2. BASIC ADJUSTMENTS
On-Screen Display Adjustment
In the condition of NO indication on the screen.
Press both VOL. DOWN button on the set and
the Channel button (9) on the remote control for
more than 2 seconds to appear the adjustment
mode on the screen as shown in Fig. 2-1.
NOTE
Use the Channel buttons (1-8) on the remote
control to select the options shown in Fig. 2-1.
Press the Channel button (0) on the remote
control to end the adjustments.
• Use an isolation transformer when performing
any service on this chassis.
• Before removing the anode cap, discharge
electricity because it contains high voltage.
• When removing a PCB or related component,
after unfastening or changing a wire, be sure
to put the wire back in its original position.
Inferior silicon grease can damage IC’s and
transistors.
• When replacing IC’s and transistors, use only
specified silicon grease (YG6260M). Remove
all old silicon before applying new silicon.
2-1: RF AGC DELAY
1. Receive an 80dB monoscope pattern.
2. Connect the digital voltmeter between the pin
5 of CP101 and the pin 1 (GND) of CP101.
3. Activate the adjustment mode display of Fig.
2-1 and press the channel button (5) on the
remote control.
4. Press the channel button (2) on the remote
control. The Fig. 2-2 appears on the display.
5. Press the VOL. UP/DOWN button on the
remote control until the digital voltmeter is
2.20 ± 0.05V.
