Advent 27.3251 TV Service Menu

Advent 30.3461 and Advent 27.3251 TV Service mode
Factory mode 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.

Alignment procedure, Module alignment Advent 30.3461 and Advent 27.3251 TV Service mode
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
display OK and it is OK, at this time, if changing channel, it should not appear flyback line. This
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.
d) Picture size position and high voltage adjustment
In component mode input 1080I signal
Use crosshatch and electrical circle signal, after entering into factory menu status, press “2”
button to enter into “FACTORY MENU 2” factory menu to adjust picture’s linearity. Adjust
R339 joint point to make the V-center deflection range be within ±5MM(T3251), or
±3MM(T2751).
Change the signal to white background, or greatly change contrast and brightness, or press
PIC button to switch among several kinds of analogue amount to make corresponding beam
current changes, adjust V-EHT-COM, H-EHT-COM to make raster’s size basicly not change
when at different beam current status.
3) According to chart 2 in turn apply every testing signal (firstly apply YpbPr signal, then TV or AV
signal), then press “5” button to enter into “FACTORY MENU 5”, adjust H-S, V-S, H-SIZE, V-SIZE to
make picture normal.
e) Sub-brightness adjustment
Receive split field signal, set colour/contrast/brightness to 0, check whether screen second gray is
slightly bright, otherwise press “6” button, in factory menu select CONTRAST MAX and BRIGHT
MAX to adjust.
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
voltage and the reading should be A value in chart 3. When brightness, contrast is set to
minimum (zero beam current), measure the high voltage,
4) High voltage protection: receive a picture signal, adjust until picture and sound are normal,
short R340 and the circuit should immediately enter into power-off protection state and the
state should keep. Turn off the power switch and then turn on, the picture and sound should
restore to before-testing state.
g) Peak value adjustment
On the condition of SCREEN and beam current has been adjusted properly, in order to show
picture’s contrast well and control picture’s colour tail, apply a little beam current picture (for
example, black and white crosshatch) and set picture’s contrast and brightness to maximum, then
after entering into factory menu status, press “4” button to enter into “RGB MENU” factory menu,
by adjusting PEAK DRIVE LIMIT item to make the whole unit’s picture colour just without colour tail
on the condition of maximum contrast and it is OK.
