M123SP Alignment Procedure

Ⅰ. Summarize

M123SP，is NTSC only system model developed for NAFTA market specially. In trial

run, burn the software to TMPA8872PSNG IC by OTP method. After the trial run,
make the mask，please take care in production. To solve the probable problems in

production, for the workers participate in alignment, please be familiar with the Alignment

Procedure, and be master of the features.

There are 2 operation modes：user mode and factory mode. You can use the Remote

control or buttons on the panel to operate in user mode, but only Remote control works in

factory mode.

The way to enter factory mode：Press “D-MODE”button on RC， press“OK”and
“CH+”“ CH-”to select the parameter you want to adjust.， Press“VOL+”“ VOL-”
to change the parameters. To quit factory mode，press“D-MODE” button（on the right
of SURR button），the factory data changed will be memorized.

A few special modes：

Aging mode — used before the aging before alignment. The aging could start in

factory mode.

Vertical stop mode—used to confirm the screen voltage. Press “INPUT”button in

factory mode to enter Vertical stop mode. Then press
“INPUT” button again to exit.

White balance alignment mode—used for white balance auto alignment. Press“BUS

OFF” button near the left of MTS button to enter White

balance alignment mode.

Factory mode—. Press “SOUND” button in factory mode to initialize the set. The

screen displays“WAIT”， after the initialization，the screen
displays “OK”，and exit the Factory mode automatically.

Then press “D-MODE”button again，it will not enable you to enter Factory mode if
you want to enter again，you need operate as follows：turn down the volume to 0 press
“Volume down”button on the panel，press“INFO”button on the

RC meantime.

2. RF AGC adjustment

AGC Alignment Procedures:

Apply 8-scale gray signal (80dB), then adjust AGC data in D-mode to get the noise

1)

picture ( snow picture) disappear exactly. Test Pin 1 of TU101 (IF output) and

record the voltage value as V1

P-P.

<Illustrate as Picture A>

2) Apply 8-scale gray signal (80dB), and then adjust AGC data in D-mode until the

synchronization signal distortion appear exactly. Test Pin 1 of TU101 (IF output)

and record the voltage value as V2

3) Calculate the value of V

with the formula: V

。

4) Test three units according to 1)，2)，3) steps, and record the values of AGC in three

units. Take the average value as benchmark.

Remarks:

Comparing test is necessary due to different probe of Oscilloscope and different Test

Circuit (Picture A).

1) AGC voltage value should be tested afresh, due to the type/supplier of Tuner

input

or Saw filter changed, or other related components changed.

3. Screen & Focus voltage adjustment

① Apply pattern signal in normal status, enter Factory mode，press“INPUT” button
to stop vertical scan. Note：(the RC/GC/BC is preset to be 40，GD/BD is 40）

Adjust the SCRREEN switch on the flyback transformer to make a horizontal shining ②

line just visible on the screen.

Turn on the vertical output, adjust the “FOCUS” on the flyback transformer to obtain ③

the optimum focus.

4. White balance adjustment (NORMAL)

1) Apply the black and white pattern in normal status;

2) Alignment of normal color temperature

① Change Color Temperature to normal status
② Use a color analyzer to measure the black side of the screen. By changing the value

of RC, GC and BC, set the reading of the color analyzer to THOMSON standard,
x=285+

8, y=294+8.

③ Use a color analyzer to measure the white side of the screen. By changing the value

nd

dark

8,

of GD, BD, set the reading of the color analyzer to THOMSON standard, x=285+
y=294+

8.

④ Separately set the brightness and contrast from min. to max., repeat the step 2 and 3

until the reading of the color analyzer is correct.

Note: Provided the production line is equipped with the self- White balance adjusting

equipment, white balance can be adjusted automatically as following: Press “BUS OFF”

button under factory mode, the TV set will adjust automatically.

THOMSON standard：

Warm X=310+

Cool X=278+

8, Y=314+8
8, Y=282+8

Remark:

1) Provided the production line is equipped with the self- White balance adjusting

equipment, white balance of M123A chassis can be adjusted automatically as following:

Press “I2C BUS” button under factory mode, the TV set will adjust automatically.

2) Free-alignment of warm and cool temperature by presetting the value of RC-W,

GC-W, BC-W, GD-W, BD-W (for warm temperature) / RC-C,GC-C,BC-C,GD-C,BD-C(for

cool temperature ) into memory

5. Adjustment of Sub-brightness

Apply the Grey-scale/Color bar (NTSC signal) to the AV input, in normal status. Enter

factory alignment menu 5, Select BRTC to adjust the sub-brightness, until that the 2

bar of 8 level Grey scale just can be seen.

6. picture geometric adjustment

1. Apply the Philips standard testing pattern in normal status, then enter menu 3,

adjusting the following data to get the min-distortion.

HPOS6（Horizontal Center） PAR A6 （Level） TRAP6 （Trapezia）

HSIZE6（Horizontal Size） CNRT6 （To p） CNRB6 （Bottom）

2. Apply the Philips standard testing pattern in normal status, then enter menu 3,

adjusting the following data to get the min-distortion.

HIGH6 (Height) VP60（Vertical Center）
VLIN6（Linearity） VSC6（Vertical-S Correction）

7. EHT/HEW ratio test（test with PC program）:

Instruments： EHT test meter，EHT test bar(1000:1)，adjustable power supply，virtual

DY( the same L value with CRT in production ).

Test means： Measure the EHT value V when Ib=0，HEW voltage value is V1(DC

voltage at 2 ends of C431).

Check means： apply PC test means，V/V1 should satisfy the requirements below：
