Many electrical and mechanical parts in this chassis have special safety-related characteristics. These
parts are identified by in the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components as
recommended in this manual to prevent Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good earth ground (Water
Pipe, Conduit, etc.) and the exposed metallic parts.
Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity.
Reverse plug of the AC cord into the AC outlet and repeat AC voltage measurements for each exposed
metallic part. Any voltage measured must not exceed 0.75 volt RMS, which is, corresponds to 0.5mA.
In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must
be checked and repaired before it is returned to the customer.

Battery installation
▶Inserting batteries
1. Remove the battery cover by pulling it upward in the direction shown by the arrow.
2. Insert the batteries with correct polarity (“+" to "+", and "-" to "-”).
3. Replace the battery compartment cover.
* Install two high-quality 1.5V "AAA" alkaline batteries. Don't mix old batteries with new batteries.
*Remove batteries when you won't use the remote controller for long time. Liquid leakage from old batteries
may cause operation failure.
Notes for using remote controller
• Make sure there are no objects between the remote controller and its sensor.
• Don't place the remote control near a heater or in damp place. Strong impact to the remote control may
cause operation failure.
• Signal from the remote control may be disturbed by sunlight or other bright light. In this case, darken the
room or move the TV.

Safety Precautions
1. Never disconnect leads while the TV receiver is on.
2. Don't short any portion of circuits while power is on.
3. The adjustment must be done by the correct appliances. But this is changeable in view of
productivity.
4. Unless otherwise noted, set the line voltage to 230Vac 10%, 50Hz. / 110Vac, 60Hz
Test Equipment required
1. RF signal generator (with pattern generator)
2. Multi meter (volt meter)
3. Oscilloscope
4. LCD Color analyzer
RF AGC (Automatic Gain Control) Adjustment
The RF AGC was aligned at the time of manufacturing for optimum performance over a wide range
conditions. Readjustment of RF AGC should not be necessary unless unusual local conditions exist, such as ;
1) Channel interference in a CATV system.
2) Picture bending and/or color beats, which are unusually due to excessive RF signal input when the
receiver is too close to a transmitting tower or when the receiver is connected to an antenna
distribution system where the RF signal has been amplified. In this case, the input signal should be
attenuated (with pad or filter) to a satisfactory level.
3) Picture noise caused by "broadcast noise" or weak signal. If the broadcast is "clean" and the RF
signal is at least 1mV (60dBu), the picture will be noise free in any area.
Adjusting RF AGC to one end of rotation will usually cause a relatively poor signal to noise ratio; Adjusting to
the other end of rotation will usually cause a degradation of over load capabilities resulting in color beats or
adjacent channel interference.
