Thank you for answer "master250".I have this service manual, but does not contain YSUS module scheme nor for ZSUS.There may yet find this scheme, it would be a great help because it is a defect contact on the board that I have not managed to track down suspected mechanical fault in one of internal components.

SAFETY PRECAUTIONS
IMPORTANT SAFETY NOTICE
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.
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.
When replacing a high wattage resistor (Oxide Metal Film Resistor,
over 1W), keep the resistor 10mm away from PCB.
Leakage Current Hot Check circuit
Keep wires away from high voltage or high temperature parts.
AC Volt-meter
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.

ADJUSTMENT INSTRUCTION
(2) Confirmation
1. Application Range
1) We confirm whether “0xF1 (offset), 0xF2 (gain)” address of
EEPROM “0xBC” is “0xAA” or not.
2) If “0xF1”, “0xF2” address of EEPROM “0xBC” isn’t “0xAA”,
we adjust once more

9-1. Purpose and Principle for Adjustment
of the Color Temperature
(1) Purpose: Adjust the color temperature to reduce the
deviation of the module color temperature.
(2) Principle : To adjust the white balance without the
saturation, Fix the one of R/G/B gain to C0 and decrease
the others.
(3) Adjustment mode: Two modes of Cool and Warm
(Cool data is automatically calibrated by the Medium data)
9-2. Required Equipment
(1) Remote controller for adjustment
(2) Color Analyzer : CA-100+ or CA-210 or same product
- PLASMA TV(ch : 10)
(1) Enter the adjustment mode of the white balance
- Enter the white balance adjustment mode at the same time
heat-run mode when pushing the power on by power only
key
- Maintain the white balance adjustment mode with same
condition of Heat-run
- Maintain after AC off/on in status of Heat-run pattern display
(2) Release the white balance adjustment mode
- Release the adjust mode after AC off/on or std-by off/on in
status of finishing the Hear-run mode
- Release the Adjust mode when receiving the aging off
command(F3 00 00) from adjustment equipment)
(3) Enter the adjust mode of white balance
- Enter the white balance adjustment mode with aging
command(F3, 00, FF)
(3) Auto W/B adjustment instrument(only for Auto adjustment)
- Do the white balance adjustment under the 10LUX
O
Color Temperature & Color Coordinates Setting
- When adjusting the Color Temperature, Color Analyzer CA210(Matrix should be corrected through CH10 of CS-1000)
should be used. When CA-210 have used, it don’t need to fit
the CH10.
- Adjust the Color Temperature based below adjustment color
coordinates.
O
Target Value CA-210(PDP : CH10), CA-100(PDP)
(Standard color coordinate and temperature when using the
CA-100+ or CA210 equipment)
[ Notice: When using the Color Analyzer with PDP,
recommend the CA-100 more than CA-210.
If CA-100 can not available, it is also good to use the CA-210.
(4) PC (for communication through RGB)
(5) Pattern Generator (MSPG-925FA etc.)
-Before white balance, press the ADJ key 2times and do
the reset like Fig. 4
-To enter White-balance mode, press the ADJ key 2times.

1) Decrease the R, G.
2. x, y & lt; target
1) First decrease the B gain,
2) Decrease the one of the others.
