IMPORTANT SAFETY PRECAUTIONS VER1.0
1-1
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 fish papers, 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 water pipe, conduit, etc.) to all
exposed metal parts of the instrument (antennas, handle bracket, metal cabinet, screw heads, 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.
2. Read and comply with all caution and safety-related notes on or inside the Monitor cabinet, on the 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.

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 wiring 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.

Analyzer.
(3) Change the PDP input mode to DVI and press the “Recall” key on the remote
control to have the PDP set recalled back to default factory settings.
(4) Set up the Video Pattern Generator (ie. Chroma, Model = C2226) with the
following settings:
a. Timing: 640 x 480 @ 60Hz,
b. Make sure the Output signal is Digital (DVI)
Connect the PDP DVI input connector to the Chroma DVI output connector.
(5) Dark level and bright levelcenter block definition:
A. Dark level center block definition:
Pattern set = Pattern name = 1-mosaic,
Color form = norm,
Background color = 0
Foreground color = 17
According to the C-2226’s user manual, appendix analog-color: Normal Pen
from Pen 17 = R: 102, G: 102, B: 102
102 (output amplifier)/1024 (total amplifier)=10%, therefore the 10% is the 10
IRE white output pattern.
B. Bright levelcenter block definition:
Pattern set = Pattern name = 1-mosaic,
Color form = norm,
Background color = 0
Foreground color = 25
According to the C-2226’s user manual, appendix analog-color: Normal Pen
from Pen 25 = R: 614, G: 614, B: 614
614 (output amplifier)/1024 (total amplifier)=60%, therefore the 60% is the 60
IRE white output pattern.
(6) There are 2different modes (DVIand RGB) that have Color Temperature settings.
For each one of these 3 modes, there are 4 different Color Temperatures (5400K,
6500D, 9300K and 13800K) that can be individually adjusted. Each Color
Temperature is adjusted through the dark level, bright level, Gain and Bias values.
