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.

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
