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 lsolation 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 circuitary 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 positioin, 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 esposed 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 sepcified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.

There are four jacks on the left side on your projection TV
that make connecting Audio/Video devices like video games
and camcorders very simple.
The jacks are like those found on the back jack connection
panel. This means that most equipment that connects to
those types of jacks on the rear jackpack, may be connect-
ed to the front connection panel.
To use the side jacks as the signal source, select them
using Main Input menu. They will be named “Front Video” in
the Main Input menu.
If you input both Front Video and
S-Video, only the S-Video will
work.
If you’re connecting a video game
device, make sure to change the
picture settings with the EZ
Picture option in the Video menu.

ADJUSTMENT INSTRUCTIONS
1. Application Object
These instructions apply to the DLP Projection TV (Chassis:
NB-05EB).
2. Notes
(1) Because this is not a hot chassis,it is not necessary to use
an isolation transformer. However, the use of an insolation
transformer will help protect test equipment.
(2) The adjustments must be performed in the correct
sequence.
(3) The adjustments must be performed in the condition of
25±5°C of temperature and 65±10% of relative humidity if
there is no other specific designation.
(4) The input voltage of the receiver must remain AC 110V,
60Hz.
(5) Unless stated otherwise, the set must be operated for at
least 5 minutes prior to adjustments.
The heat-run should be performed with a 100% white
pattern,but reception of a moving picture may also be
possible in unavoidable cases.
3. Composition of Adjustment Mode
(1) Adjustment modes are entered by pressing the ADJ key
on the Service Remote Control, after adjustments press
the ADJ key to exit.
(2) Initial Adjustment mode Menu is shown below. <Fig. 1>
(3) As shown <Fig. 1>, using the CH+ (D), CH- (E) keys to
select an item, press the ENTER or VOLUME+ (G) keys to
enter the appropriate item and begin adjustment.
(4) Change the value of adjustment by using the volume +(G),
volume -(F) keys. To change adjustment item, use the
CH+ (D), CH- (E) keys in EZ ADJ Mode.
(5) Press the ADJ key to exit, after adjustments.
(6) Preparation for Adjustment
1) Connect the power to TV Set and set “Power on”.
2) Allow set to Heat-Run for at least 5 minitues before
adjusting.
4. Adjusting the Optical Engine
(1) After placing the optical engine on the JIG, adjust
illuminator by adjuting with automatic adjustment the B as
shown <Fig. 2>.
1) When adjust illuminator, search the scope does not fall
in illuminator and Tilt adjustment complete with
automation equipment in that scope.
2) After adjusting, A fix with Screw using automation
equipment.
(2) In order to move Optical system the Tilt is adjusted to
center of the screen, adjust using automation equipment
the A(Projection Lens) as shown <Fig. 3> and adjust
Position. (Refer to Automatic Adjustment Sequence)

(3) After adjusting the illuminator, adjust the focus by using
the focus adjustment screw on the projection lens. After
adjusting, fasten the screw tighty and secure with sealer.
[Note: The focus check point is not the screen center but the
upper/lower screen.
[Pattern for focus adjustment
(1) Enter the Cross Hatch using (CH + (D), CH - (E)) Key.
(Pattern Sequence: Cross Hatch --> Red --> Black -->
White --> Gray --> Blue --> White Balance)
(2) Focus adjustment Knob is variable and adjust the Focus.
(3) Adjust/check the Focus of marking part to be equal.
1) Focus: Center Best
2) Flare: 1.5pixel below(Engine)
(4) After adjusting, fix the adjustment Knob
5. Caution for DMD
(Digital Micro-mirror Device)
5-1. Caution for DMD ESD
(1) Use a grounding strap to prevent ESD (Electrostatic
Dischage) damage when handing the DMD.
(2) Connect the grounding strap to a ground point on the
workbench.
(3) Keep the DMD in an ESD Safe container when not being
used or in transit.
(4) Wearing gloves will help prevent ESD damage and help
preserve the physical condition of the DMD.
(5) All work should be performed in a static free environment.
(6) Use caution and remove any dust particles on the DMD
front glass or back pins/pads.
5-2. Caution for DMD Cleaning
(1) Use caution to prevent scratches to the DMD glass.
(2) When DMD glass stains with dust, polish the front and
back DMD glass with soft cloth. Then, rotate the DMD 180
degrees and polish again.
(3) Do not use pressure when cleaning the DMD. The static
electricity and pollution can damage the DMD.
