IMPORTANT SAFETY PRECAUTIONS VER1.0

1. Before returning an in s trument t o the cu stome r,

always make a saf ety chec k of the entir e instr um ent,

including, but not limited to, the following items.

a.

Be sure that no built-in protective devices are defective a nd/or have been defeated during servic ing. (1)
Protective shields are pr ovided on this chassis to protect both the technicia n and the customer. Correctly
replace all missing protective shields, including any removed for servicing convenience. (2) When
reinstalling the chass is 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 ther e are no cabinet op enings through which an adult or child might be able t o insert their

fingers into, Such ope ning include, but are not lim ited to, (1) spacing between the pic ture tube and the
cabinet mask , (2) exc es sively wide cabinet ventila tio n s lots, and ( 3) an improperly fitted and/ or inc or rec tly
secured cabinet back cover.

c. Leakage Current Check

—

—With the instrument completely reassembled, plug the AC line cord directly into

——

a 120V AC outlet. (Do not use a n isolatio n trans former dur ing this test.) Use a le akage cur rent tester or a
metering system that complies with American National Standards Institutes (ANSI) C101.1 Leakage
Current for Appliances and Underwriter s Laboratories (UL) 478. W ith the instrument AC s witch first in the
ON position and th en in t he O FF pos it ion, measure from a k nown ear th gr oun d ( metal water pipe, cond uit ,
etc.) to all exposed m etal parts of the inst rument (antennas, h andle bracket, m etal cabinet, scr ew heads,
metallic overla ys, control shafts, etc .), especially any exposed metal parts that offer an electrical return
path to the chass is. Any current m easured must not exceed 3.5 m illiamp. Revers e the instrument po wer
cord plug in the outlet and r epeat 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.

Read and comply with all caution and safety-related notes on or inside the Monitor cabinet.

3. Design Alteration Warning

—

—Do not alter or add to the mechanical or electrical design of this unit. Design

——

alterations and add itions, including, but not limited to, circuit modif ications and the addition of th e items
such as auxiliary audio and/or video output connections might alter the safety characteristics of this
Monitor and create a hazard to the user. Any design alteratio ns or additions will void the manufactur er’s
warranty and will make you, the service, responsible for personal injury or property damage resulting there
from.

AC power plug is inserte d so that the chassis is c onnected to the groun dside of the AC p ower source. To
confirm that the AC power plug is ins erted cor rectly us e an AC voltm eter to m easure the vol tage potent ial

reinsert the AC power plug in opposite pol arity and re-m easure the voltage p otential b etween the chas sis

ground systems are electrically separated by insulating material that must not be defeated or altered.

parts,
or frayed wiring. Do not change the spacing between components or the spacing between the
printed-circuit board and components. Last but not least, visually check the AC power cord to ensure no
outer appearance damage is present.

6.

Components, parts, and /or wiring that appear to have overheated or are otherwis e damaged should be
replaced with com ponents, parts, or wiring tha t meet original specificat ions. Additionally, determine the
cause of overheating and/or damage and, if necessary, take corrective action to remove any potential

Color Temperature Adjustment

2. Pre-setting Adjustment and Equipment Preparation:

(1) Turn on the PDP and let it warm up for at least 30 minutes.
(2) Turn on the Color Analyzer (ie. Minolta, Model = CA-100) and reset the Color

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 level center 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 level center 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 3 different modes (DVI, RGB and AV) 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.

x=335 y=343
GAIN BIAS
R G B R G B
X X X X X X

*Note: When adjusting the DVI and RGB color temperatures, please set
the PDP input source so that it matches the color temperature source
being adjusted (DVI color temp. to be adjusted with DVI source under DVI
mode, RGB color temp. with RGB source under RGB mode, AV color
temp. with Composite source under AV1 mode).*

(8) Flatly place the Minolta Color Analyzer’s Photo Detector in contact with the

center of the PDP screen.

the Factory Adjustment key sequence as stated in point (7) above. The DVI
5400K Color Temperature setting menu will appear after choosing the Color
Temperature Adjustment option.

(2) Press the Left/Right Button to switch between the Bias (R, G, B) and Gain (R, G,

B) values. Use the Up/Down Buttons to change the Bias and Gain Values.

(3) 5400K dark level center block adjustment procedure:

Y = 0.4±0.08 FL

(4) 5400K bright level center block adjustment procedure: (Please set the Chroma

C-2226 DVI bright level center block signal to 60 IRE)

A. Select G-GAIN and adjust the G-GAIN value until Y = 30±0.8 FL.
B. Select R-GAIN and adjust the R-GAIN value until x = 335±8
C. Select B-GAIN and adjust the B-GAIN value until y = 343±8
D. Repeat steps A, B and C until the following final values are obtained:

x = 335±8
y = 343±8
Y = 30±0.8 FL

(3) Set up the Video Pattern Generator (Chr oma, M odel = C 2226) with the following

settings:
a. Timing: 640 x 480 @ 60Hz,
b. Make sure the Output signal is Analog (RGB)
Connect the PDP RGB input connector to the Chroma C-2226 RGB output
connector.

(4) Dark level and bright level center block definition:

C. 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.

D. Bright level center 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
