SAFETY PRECAUTIONS
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 X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
General Guidance
An isolation Transformer should always be used during
the servicing of a receiver whose chassis is not isolated from
the AC power line. Use a transformer of adequate power rating
as this protects the technician from accidents resulting in
personal injury from electrical shocks.
It will also protect the receiver and it's components from being
damaged by accidental shorts of the circuitry that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace
it with the specified.
When replacing a high wattage resistor (Oxide Metal Film
Resistor, over 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to high vacuum and large surface area of picture tube,
extreme care should be used in handling the Picture Tube.
Do not lift the Picture tube by it's Neck.
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source,
connect an electrical jumper across the two AC plug prongs.
Place the AC switch in the on position, connect one lead of
ohm-meter to the AC plug prongs tied together and touch other
ohm-meter lead in turn to each exposed metallic parts such as
antenna terminals, phone jacks, etc.
If the exposed metallic part has a return path to the chassis, the
measured resistance should be between 1MΩ and 5.2MΩ.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before the
receiver is returned to the customer.
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 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.

Watching VCR
- When connecting the Monitor to external equipment, match the colours of connecting ports (Video - yellow, Audio (L) - white,
Audio (R) -red).
- Connect the VIDEO OUTPUT socket (yellow) to the VIDEO INPUT on the set.
- If you have a mono VCR, connect the audio cable from the VCR to the AUDIO (L/MONO) input on the set.
- If you connect an S-VIDEO VCR to the S-VIDEO input, the picture quality is improved; compared to connecting a regular VCR
to the Video input.
- Use the orbiter function to Avoid having a fixed image remain on the screen for a long period of time. Typically a frozen still picture from a VCR. (Refer to p. 28)
If a 4:3 picture format is used; the fixed image may remain visible on the screen.
- To avoid picture noise (interference), leave an adequate distance between the VCR and the set.
Watching TV programmes
- Turn the set on and select the programme you
want.
Watching VCR
1. Use the TV/AV button on the remote control to
select VIDEO 1 or VIDEO 2.
- If both S-VIDEO and VIDEO sockets have been
connected to the S-VHS VCR simultaneously, only
the S-VIDEO can be received.
2. Insert a video tape into the VCR and press the
PLAY button on the VCR.

Connecting PC
How to connect
1. To get the best picture quality, adjust the PC graphics card to 1024x768, 60Hz.
2. Use the set’s RGB INPUT or DVI (Digital Visual Interface) INPUT port for video connections, depending on your PC connector.
If the graphic card on the PC does not output RGB and DVI simultaneously, connect only one of either RGB INPUT or DVI
INPUT to display the PC on the set.
3. Then, make the corresponding audio connections. If using a sound card, adjust the PC sound as required.
How to use
1. Turn on the PC and apply power to the set.
2. Press the MENU button and then
DD / EE
button to select the SPECIAL menu.
3. Press the GGbutton and then
DD / EE
button to select Main input.
4. Press the GGbutton and then
DD / EE
button to select RGB-PC, RGB-DTV, DVI-PC or DVI-DTV.
PC screen appears on the set.
The set can be operated as the PC monitor.
5. Check the image on your set. There may be noise associated with the resolution, vertical pattern, contrast or brightness in PC
mode. If noise is present, change the PC mode to another resolution, change the refresh rate to another rate or adjust the brightness and contrast on the menu until the picture is clear. If the refresh rate of the PC graphic card can not be changed, change
the PC graphic card or consult the manufacturer of the PC graphic card.
Note:
a. Depending on the graphics card, DOS mode may not work if you use a DVI-D cable.
b. Avoid keeping a fixed image on the TV's screen for a long period of time. The fixed image may become permanently imprinted
on the screen.
c. The synchronization input form for Horizontal and Vertical frequencies is separate.

(1) Because this is not a hot chassis, it is not necessary to use
an isolation transformer. However, the use of isolation
transformer will help protect test equipment.
(2) Adjustments must be done in the correct order.
(3) The adjustments must be performed in the circumstance of
25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.
(4) The input voltage of the receiver be must kept 220V, 60Hz
when adjusting.

(2) Vs Adjustment
1) Connect + terminal of D.M.M to Vs pin of P805 and
connect – terminal to GND pin of P805.
2) Adjust RV401 voltage to match that of the label on the
Top/Right of the panel. (Deviation : ±0.5V)
If you turn on a still screen more than 20 minutes (Especially
Digital pattern(13 CH), Cross Hatch Pattern), an afterimage
