CAUTION: THIS SERVICE MANUAL IS ONLY FOR PROFESSIONAL SERVICE PERSONNEL'S
REFERENCE. BEFORE SERVICING THIS CHASSIS, PLEASE READ THE
FOLLOWING NOTICE ITEMS.
1. INSTRUCTION
Before servicing and aligning this equipment, please read the following "X-RAY RADIATION
PRECAUTION" ,"SAFETY PRECAUTION" and "PRODUCT SAFETY NOTICE".
1.1 X-RAY RADIATION PRECAUTION
1 Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such
hazards, the high voltage must not be above the specified limit. The normal value of the high
voltage of this receiver see below chart:
Chart 1 High voltage requirement
High voltage normal
Model Utmost value Beam current
value
T2751 30 kV 1 kV 35 kV 1.6 mA
T3251 30 kV 1 kV 35 kV 1.6 mA
2 Each time a receiver requires servicing, the high voltage should be checked following the HIGH
VOLTAGE CHECK procedure in this manual. It is recommended the reading of the high voltage
be recorded as a part of service record. It is important to use an accurate and reliable high voltage
meter.
* When checking, main power (B+) should be kept at 135 V (for Toshiba pure flat CRT).
3 The primary source of X-RAY RADIATION in this TV receiver is the picture tube. For continuous
X-RAY RADIATION protection, the replacement tube must be exactly the same type tube as
specified in the parts list.
4 Some parts in this receiver have special safety-related characteristics for X-RAY RADIATION
protection. For continuous safety, parts replacement should be undertaken only after referring to
the PRODUCT SAFETY NOTICE below.
1.2 SAFETY PRECAUTION
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precaution on this receiver.
The following are the necessary precautions to be observed before servicing this chassis.
1) Since the power supply circuit of this receiver is directly connected to the AC power line, an
isolation transformer should be used during any dynamic service to avoid possible shock hazard.
2) Always discharge the picture tube anode to the CRT conductive coating before handling the
picture tube. The picture tube is highly evacuated and if broken, glass fragments will be violently
expelled. Use shatter proof goggles and keep picture tube away from the unprotected body while
handling.
1
3) When replacing a chassis in the cabinet, always be certain that all the protective devices are put
back in place, such as: non-metallic control knobs, insulating covers, shields, isolation
resistor-capacitor network etc.
4) When replacing parts or circuit boards, disconnect the power cord.
5) When replacing a high wattage resistor (oxiode metal film resistor) on the circuit board, keep the
resistor 10mm (1/2in) away from circuit board.
6) Connection wires must be kept away from components with high voltage or high temperature.
7) If any fuse in this TV receiver is blown, replace it with the FUSE specified in the chassis parts list.
1.3 PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the chassis have special safety-related characteristics.
These characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION
protection afforded by them cannot necessarily be obtained by using replacement components rated
for higher wattage, etc. Replacement parts which have these special safety characteristics are
identified in this manual and its supplement electrical components having such features are shaded
on the schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The use of
substitute replacement parts which do not have the same characteristics as specified in the parts list
may create shock, fire, X-RAY RADIATION or other hazards.

2 Alignment procedure
2.1 Instruction
a) In this chassis since there are a great amount of data needed to be set, these setting all are stored
in E2PROM. To reduce the alignment working, use the aligned E2PROM as a female parent to
copy and then use them. Or refer to appendix chart and preset E2PROM value and then use.
b) To conduct the alignment, the power supply should be AC120 V,60 Hz. The whole unit should be
preheated for 30 minutes.
c) To conduct with color purity, convergence, white balance alignment or other alignment relative to
color, the CRT should be degaussed thoroughly.
d) Since this chassis adopts modulization structure, before mounting, every module should be
conducted with alignment.
e The factory menu's alignment should use XOCECO RC-T03-0A remote control. Press power
switch to turn on the set, in turn press button "SLP-MUTE-AV-MENU" to enter into factory menu.

Press SLP or 0 button to exit. Press MUTE button to preset before Out-factory.
f) For the supporting mode in this set see below chart 2.

2.2 Alignment procedure
2.2.1 Module alignment
In all the module alignment, use a normal working TV set as an alignment frock, pull the set's
corresponding module and keep it as an example. Insert the module wanted to be check,
then apply power to alignment.
a) AV board module
AV interface function check: check all the AV input/outputs function, it should meet the Product
Standard requirements.
b) Digital processing board module
No alignment point, apply the power and check whether S-VIDEO, YCbCr, YpbPr input is normal.
c) Main board
No alignment point. Apply the power and measure "B+" voltage, the reading should be 105V,
check there are no assemble error, the OSD,SVM is normal, and it is OK.
2.2.2 Chassis adjustment
Correctly insert all modules and parts, connect CRT board parts to CRT, apply power and
check B+ voltage, the reading should be 105V. (on J332/J305)
2.2.3 The whole unit adjustment
Be sure the whole unit has been preheated for 30 minutes.
a) Focus adjustment
1) In TV mode receive crosshatch signal, at the same time set SVM to OFF.
2) Adjust FOCUS inductance L306 on Dynamic Power Board to make R323 dynamic focus
voltage be 1KV+/-50V.
3) Adjust FOCUS potentiometer on FBT and CRT to make horizontal and vertical grid both
thinnest, and consider horizontal grid mainly.
4) Set SVM to ON, check the whole effect.
b) Dark current (SCREEN voltage) adjustment
In TV mode receive gray scale signal, after entering into factory menu status, press "1" button to
enter into "FACTORY MENU 1" factory menu, first preset WHITE-R, WHITE-G, WHITE-B's
value all to 0, adjust SCREEN potentiometer to make SCREEN LOCK on the screen lower part

state should also be OK after finish adjusting the white balance. .
c) White balance adjustment
Adjust on the basis of the above step, at standard status use gray scale signal to adjust.
1 Press "1"button to firstly adjust TV input white balance: fix the testing point at about 40 nits gray
scale, then by adjusting WHITE-R,WHITE-G and WHITE-B to make the value meet chart 3's
requirement.
2 Press "5" button to adjust YpbPr input white balance: use oscilloscope to measure Y signal
output on Digital Processing Board. Adjust G-0 gray scale to make blanking level be even with
black level, adjust G-G to make signal amplitude to be 0.7V and eight level gray scale be even,
then adjust R-G, B-G, R-0, B-0's value to make white balance meet chart 3's requirement.

f) Filament/beam current/high voltage check and adjustment
1) Filament voltage: receive a TV program signal, set picture mode to "STANDARD",the filament
voltage effective value should be 6.3 0.2 Vrms.
2) Beam current check: receive all white field signal, set picture mode to "SPORTS", measure
R360 two terminals' voltage and the reading should be less than or be equal to 1.6V. If not,
after entering into factory menu status, press "4" button to enter into "RGB MENU" factory
menu, adjust AV BEAM LIMIT item to make beam current meet requirements.
3) High voltage check: receive D8 signal, set picture mode to "STANDARD", measure CRT high

4.General description of the SDA 9380-B21.
The SDA 9380 is a highly integrated deflection controller and RGB video processor for CTV
receivers with 15 to 19kHz or 31 to 38kHz line frequencies. The deflection component controls
among others a horizontal driver circuit for a flyback line output stage, a DC coupled vertical
saw-tooth output stage and an East-West raster correction circuit. All adjustable output
parameters are I2C-Bus con-trolled. Inputs are HSYNC and VSYNC. The HSYNC signal is the
reference for the internal clock system which includes the ¦µ1 and ¦µ2 control loops.
