Alignment Procedure
一、Summarize：
27F230T/24FS210T chassis Alignment Procedure
29185N6/25185N6，is NTSC only system model developed for NAFTA market
specially. In trial run, burn the software A27V01-TO to TMPA8809 or TMPA8827 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— To initialize the set. Press “SURR” button in factory mode
to enter Factory mode，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.

Alignment procedure
二．Alignment contents：
1. Adjustment of B+ voltage：
Receive Philips standard testing pattern to RF input.
Adjust VR821 in STANDARD mode until voltage at B＋＝130V±0.5V。
2. RF AGC adjustment
Observe monitor the collector waveform of Q101 with the probe of Oscilloscope as
illustration below. Select channel 2 (>70dB) from the antenna input. Enter D-mode,
select menu6 to adjust RFAGC item until the monitor peak value to 0.8V

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 80，GD/BD is 40）
Adjust the SCRREEN switch on the flyback transformer to make a horizontal ②
shining line just visible on the screen.
Turn on the vertical output, adjust the “FOCUS” on the flyback transformer to ③
obtain the optimum focus.
4. White balance adjustment(NORMAL:X=285+8, Y=294+8)
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 X=285+8,
Y=294+8.
③ Use a color analyzer to measure the white side of the screen. By changing the
value of GD, BD, set the reading of the color analyzer to X=285+8, 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.
(Warm: X=310+8, Y=314+8;Cool: X=278+8, Y=282+8)
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 2nd dark 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） PARA6 （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 C249).
Check means： apply PC test means，V/V1 should satisfy the requiments below：
EHT/HEW ratio
29185N6
(27F230T)
25185N6
(24F210T)

1245 ±3% ( 1207 ～ 1282)
1256±3% ( 1218 ～ 1293 )
8、X rays over voltage protecting circuit test:
TV enter working mode，apply more than 27V DC voltage between two ends of
C249，the set should enter protecting mode，or check X rays protecting circuit.
