SAFETY PRECAUTIONS VER1.0
A
1. Before returning an instrument to the customer, always make a safety check of the entire instrument,
including, but not limited to, the following items.
a. Be sure that no built-in protective devices are defective and/or have been defeated during servicing. (1)
Protective shields are provided on this chassis to protect both the technician and the customer. Correctly
replace all missing protective shields, including any removed for servicing convenience. (2) When
reinstalling the chassis and/or other assembly in the cabinet, be sure to put back in place all protective
devices, including, but not limited to, nonmetallic control knobs, insulating fishpapers, adjustment and
compartment covers/shields, and isolation resistor/capacitor networks. Do not operate this instrument
or permit it to be operated without all protective devices correctly installed and functioning.
b. Be sure that there are no cabinet openings through which an adult or child might be able to insert their
fingers and contact a hazardous voltage, Such opening include, but are not limited to, (1) spacing
between the picture tube and the cabinet mask, (2) excessively wide cabinet ventilation slots, and (3) an
improperly fitted and/or incorrectly secured cabinet back cover.
c. Leakage Current Hot Check—With the instrument completely reassembled, plug the AC line cord directly
into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester
or a metering system that complies with American National Standards Institutes (ANSI) C101.1 Leakage
Current for Appliances and Underwriters Laboratories (UL) 478. With the instrument AC switch first in the
ON position and then in the OFF position, measure from a known earth ground (metal waterpipe, conduit,
etc.) to all exposed metal parts of the instrument (antennas, handle bracket, metal cabinet, screwheads,
metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return
path to the chassis. Any current measured must not exceed 3.5 milliamp. Reverse the instrument power
cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED
HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE
RETURNING THE INSTRUMENT TO THE CUSTOMER.

Projection Monitor chassis, or on the picture tube.

3. Design Alteration Warning—Do not alter or add to the mechanical or electrical design of this unit. Design
alterations and additions, including, but not limited to, circuit modifications and the addition of the items
such as auxiliary audio and/or video output connections might alter the safety characteristics of this
Projection Monitor and create a hazard to the user. Any design alterations or additions will void the
manufacturer’s warranty and will make you, the service, responsible for personal injury or property
damage resulting therefrom.
1-1
SAFETY PRECAUTIONS VER1.0
4. Hot Chassis Warning—a. Some Monitor chassis are electrically connected directly to one conductor of
the AC power cord and may be safely serviced without an isolation transformer only if the AC power plug
is inserted so that the chassis is connected to the ground side of the AC power source. To confirm that the
AC power plug is inserted correctly, with an AC voltmeter measure between the chassis and a known
earth ground. If a voltage reading in excess of 1.0V is obtained, remove and reinsert the AC power plug in
opposite polarity and again measure the voltage potential between the chassis and a known earth ground.
b. Some Monitor chassis normally have 85V AC (RMS.), between chassis and earth ground regardless of
the AC plug polarity. These chassis can be safely serviced only with an isolation transformer inserted in
the power line between the receiver and the AC power source, for both personnel and test equipment
protection. c. Some Projection Monitor chassis have a secondary ground systems in addition to the main
chassis ground. This secondary ground system is not isolated from the AC power line. The two ground
system are electrically separated by insulating material that must not be defeated or altered.
5. Observe original lead dress. Take extra care to assure correct lead dress in the following areas: a. near
sharp edges, b. near thermally hot parts—be sure that leads and components do not touch thermally hot
parts, c. the AC supply, d. high voltage, e. antenna wiring. Always inspect in all areas for pinched,
out-of-place, or frayed wiring. Do not change spacing between components, and between components
and the printed-circuit board. Check AC power cord for damage.
6. Components, parts, and/or wiring that appear to have overheated or are otherwise damaged should be
replaced with components, parts, or wireing that meet original specifications. Additionally, determine the
cause of overheating and/or damage and, if necessary, take corrective action to remove any potential
safety hazard.
7. PRODUCT SAFETY NOTICE—Many Monitor electrical and mechanical parts have special safety-related
characteristics some of which are often not evident from visual inspection, nor can the protection they give
necessarily be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts
that have special safety characteristics are identified in this service data by shading with a mark on
schematics and by shading or a ＊ mark in the parts list. Use of a substitute replacement part that does
not have the same safety characteristics as the recommended replacement part in this service data parts
list might create shock, fire, and/or other hazards.

FACTORY ADJUSTED METHOD VER1.0
1. Color temperature adjustment
Push the factory service key to into the adjustment mode. The picture will appear as
follow
DVI
7180ºk
X=308 Y=298
GAIN Bias
RGB RGB
XXX XXX
Use the AV key to select the color to adjust andorkey to adjust the level.
The required equipments are CA-100,Vp300.
a. Adjust Bias first to let the Y be 0.4 on CA-100. Adjust R or B to let the value
of X,Y on CA-100 be the same as the value showing screen, The value of Y
should be Maintained 0.55 during the adjusting.
b. Move the cursor to adjust Gain. The value of Y should be adjusted to 35.
Then adjust R or B to let the value of X,Y on CA-100 be the same as the
value showing on screen. The value of Y should be maintain 20 during the
adjustment.
c. Repeat to check the Bias and Gain. The value of Y,X and Y should be the
same as the previous adjusted value. Then the DVI 7180ºk mode is adjusted
completely.
d. Push the factory service key again to next picture. Then repeat the steps a.
b. c. to adjust.
e. If the adjustment is completed, repeat d. a. b. and c steps to adjust again.
f. When the last mode AV 10180ºk is adjusted completely, push the factory
service key again to leave the adjustment mode,
Note: 1. There are 9 adjusted modes(DVIx3.RGBx3 Avx3)
2. The adjusted sequence is DVI´RGB´AV.
3. DVI: Bias Y=0.55
Gain Y=36
RGB: Bias Y=0.70
Gain Y=36
