Service default mode (SDM)
The service default mode is a pre-defined mode
which can be used when for faultfinding
(especially when the TV gives no picture at all).
All oscillograms and DC voltages in this service
manual are measured in the service default
mode.
Entering the service default mode can be done
in 2 ways:
1. By short-circuiting the service pins S1 and S2
of the microcomputer (pin 7 of IC7600) while
switching on the set with the mains switch
2. From normal operation mode by pressing the
button “DEFAULT’ on the DST (Dealer
Service Tool) RC7150.
Leaving the service default mode to normal
operation can only be done by the stand-by on
the remote control (so not via mains switch “off”;
after mains switch “off” and then “on” again the
set will start up in the Service Default Mode
again to enable easy faultfinding).
Functions of the service default mode
(see Fig. 8.1):
1. All analog settings (volume, contrast,
brightness and saturation) are in the mid
position (in µC with V1 .0 the volume in the
SDM is set at 25%, from V1 .1 onwards the
volume in the SDM is set at 50%).
2. For VST sets are to program number 1
indicated in the right top corner
3. For PLL sets are tuned to 475.25 MHz
4. Delta volume settings are not used (delta
volume setting per program in reference with
the PP volume setting which is valid for all
programs)
5. OSD error message (present available error
code) is displayed continuously
6. Store open and store close commands will act
as search and auto store
7. Automatic switch off function (set switches
“off” after iS minutes no DENT) will be
switched off
8. Hotel mode will be disabled
9. All other functions remain normal controllable
10.A counter in the middle of the screen indicate
the normal operation hours of the set in a
hexadecimal code (every time the set is
switched “on” the counter is incremented by 1
hour, so +1 at the counter).
11.An “Sin the middle of the screen (next to the
counter) indicate that the set is in the service
default mode

Fig. 8.1
Service Menu (SM)
Entering the service menu can be done in 2
ways:
1. From service default mode by simultaneously
pressing the buttons “-” and “+” buttons on the
local keyboard.
2 From normal operation mode by pressing the
button “ALIGN” on the DST RC7150.
Leaving the service menu to normal operation
can be done in 2 ways:
1. Via the stand-by on the remote control
2. Via mains switch “off”
For reading a new option setting, the set must
be switched “on” by the mains switch (so not by
stand-by as by then the EEPROM settings are
not read).
Functions of the service menu (see Fig 8.2);
1. Software version of the microprocessor used
in that typical set is displayed in the right top
corner
2. A counter in the middle of the screen indicate
the normal operation hours of the set in a
hexadecimal code (every time the set is
switched “on” the counter is incremented by 1
hour, so +1 at the counter).
3. The “S” in the middle of the screen next to the
counter indicate that the set is in the service
default mode
4. Error code history; The 5 last different error
codes occurred are stored in the EEPROM
memory; last error code detected will be
displayed on the right side (see for an
overview of all possible error codes Fig. 8.4),
so e.g.:
0 0 0 0 0
means no error codes present in the buffer
0 0 0 0 3
means one error code present in the buffer;
error code 3
0 0 0 3 2
means two error codes present in the buffer;
last detected error code is error code 2,
previous detected error code is error code 3
The error code history buffer is cleared as soon
as the Service Menu is left by the stand-by
command. In case the Service Menu is left by
the mains switch “off” the error code history
buffer will not be cleared.

5.Option setting;
The options of the set can be changed in the
service menu. In the 2 bottom lines the options
are given. Control of the options is with the
following keys on the remote control:
* PROGRAM +/-
Select the option to be changed;
Via the “PROGRAM +/-” button to option to be
changed can be selected by scrolling through
the possible options in the upper row from left to
right (via the “PROGRAM +” button) or from
right to left (via the “PROGRAM -” button). The
selected option will be displayed in the upper
row, the present “Y” or “N” status of that option
(see table 8.3) will be blinking in the bottom row
(when arrived at the end of the row the scrolling
will be continued at the other side).
* MENU +/-
Change the selected option: via “MENU +/-”
buttons the selected option can be changed.
The selected Y (yes) or N (no) blinks and via
either “MENU +“ or the “MENU you toggle
through the “Y” or “N” possibility.
The options (both the changed and the not-
changed options) are stored in the EEPROM as
soon as the service menu is left (by stand-by or
mains switch “off”). The new option settings are
only read after mains switch “on” (so not after
switching on the set from stand-by mode).
The following table indicates the possible
options and there technical consequences:
Error messages
The microcomputer also detects errors in
circuits connected to the I 2C (Inter IC) bus.
These error messages are communicated via
OSD (On Screen Display) and a flashing LED
both in normal operation and in the service
menu (error code history buffer):
1. In normal operation;
In normal operation both the “OSD error
message” and the “LED error” indication will
display the present detected error. The display-
ing of both the OSD and the LED error indica-
tion will only take a limited time.
2. In the service default mode;
In the service default mode both the “OSD error
message and the “LED error” indication will
display the present detected error. In the service
default mode both the OSD and the LED error
indication will be displayed permanently.
3. In the service menu;
In the service menu both the “OSD error
number” (in the error code history) and the “LED
error” indication will display the present detected
error. In the service default mode both the OSD
and the LED error indication will be displayed
continuously.
Reset volume/program (delta volume) for all
programs at once
It is also possible to leave the service menu with
the MENU button. After one time pressing the
MENU button in the service menu, a new menu
is entered (see Fig. 8.5) in which the volume/
programs-settings (also called delta volume
settings) of all programs can be deleted. In case
YES is selected via the MENU + button, all
volume/program-settings are deleted at once.
After another time pressing the MENU button
the TV will switch to normal operation (when the
service menu is entered via the pins S1 and S2)
or service default mode (when the service menu
is entered with the DST).

Hotel mode
* Hotel mode “on”
The hotel is activated when pressing simultane-
ously the “MENU” button on the local keyboard
and the “SLEEPTIMER or OSD” button on the
remote control while program 38 is selected for
at least 3 seconds.
When the hotel mode is activated, this is
indicated by a “H+” on the OSD (this will be
displayed until the set is switched of by the
mains switch or via stand-by).
* Hotel mode “off”
Repeat above mentioned procedure once again.
When the hotel mode is de-activated, this is
indicated by a “H-” on the OSD (this will be
displayed until the set is switched of by the
mains switch or via stand-by).
* Functions of the hotel mode
- The volume present on the moment the hotel
mode was switched “on” is the maximum
volume level in the hotel mode.
- The install mode can not be opened (the
message “LOCKED” will be displayed for 3
seconds if a store open command is given).
- The delta volume menu can not be entered.
- PP (personal preference) can not be stored
(the message “LOCKED” will be displayed for
3 seconds if a PP-store command is given).
- At switch “on” (by mains switch or remote
control) program number 1 will always be
selected.
Service Information
1. New chassis for 14”-15”-17”-21” mini neck
(neck diameter 20 mm) and 20-25-28” narrow
neck (neck diameter 30 mm) AA5 sets
In 14”-15”-17”-21” mini neck and 20”-25”-28”
narrow neck AA5 sets with production code
PM/QG 05 and higher, a new power supply is
introduced. This new power supply is the
SMPS power supply of the AA5 AB, in stead
of the SOPS power supply of the AA5 AA. As
a result the AA5 AB service manual can be
used (on the rear side of these sets, AA5 AB
is indicated) except for some component
values. These different component values and
there service codes are indicated in this
service information. The PWB is the same as
in the AA5 AB service manual.
To conclude: For 14”-15”-17”-21” mini neck and
20”-25”-28” narrow neck AA5 sets with PM/QG
code 05 and higher, use the AA5 AB service
manual (4822 727 20783 up to and included
4822 727 20788) together with this service

2. 110°East/West correction panel for 25”
and 28” AA5 AB chassis (diagram C)
For the 25 and 28” AA5 sets a 110°panel is
needed for E/W correction. This panel is
allocated on the right hand side of the chassis
(seen from the rear). The panel inclusive the
bracket can be released from the heatsink by
pulling it back. The panel itself can be taken out
of the bracket by releasing the catching lips. To
put the main carrier in the service position (see
service manual), the 110°panel has to be
released first and put aside of the main carrier.
In this service information the description, the
adjustments, the PWB and the spare parts list of
110°panel are published.
Description E/W panel 25’ and 28” AA5 AB
chassis (diagram C):
E/W correction is in this panel based on the
diode-modulator principle. This panel consists of
D6401-D6402-C2403 and C2404. By modulat-
ing the voltage on the cathode of D6402, the
current through the horizontal deflection coil is
modulated. As this is done by a parabolic-
shaped voltage, E/W distortion is corrected. This
parabolic-shaped voltage is derived from the
sawtooth-shaped voltage of the frame deflec-
tion. This is done by transistor T57403. E/W
correction is adapted for 4/3 and 16/9 mode by
Transistors T57405 and T57406. Coil 5401,
R3402, R3423 and R3424 are for the linearity
correction. R3402, R3423 and R3424 are for the
linearity correction. D6404, R3403 and C2402
compensate the Mannheim effect.
Transformer 5402 takes care for optimal
functioning of the diode-modulator. A too high
beam-current influences the EHT-voltage and
will in this way distortion the picture. This is
corrected by feeding the beam-info to T57402.
Adjustments:
• R3421 takes care for the vertical picture shift.
• R3411 is for adjusting the picture-width.
• R3413 is for correcting the E/W distortion.
3. Separate control panel AA5 AB chassis
(diagram D)
The separate controls panel (diagram D) is
allocated underneath the picture tube. To
release the panel first the main carrier should be
in its service position. After that the fixing screw
of the bracket holding the separate control panel
can be loosened. By then, the panel the
separate control panel can be taken out of its
bracket. In this service information the PWB and
the spare parts list of the separate control panel
is published.
