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

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.

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 information.
Fig. 8.5
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 modulat­ing the voltage on the cathode of D6402, the current through the horizontal deflection coil is modulated. As this is done by a parabolic­shaped voltage, E/W distortion is corrected. This parabolic-shaped voltage is derived from the sawtooth-shaped voltage of the frame deflec­tion. 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. Separate control panel is in functionality equal to the controls on the main carrier. The following selection table is valid:
1 speaker 16Ω 2 speakers 8Ω in series 1 H34 - 2H34 1H34 - 3H34 speaker right
1H35 - 3H35 speaker left
4. Difference tables Comparing the diagrams published in the AA5 AB service manual (4822 727 20783 ... 4822 727 20788) there are several value changes for the different screen sizes. This different values are published in the following difference tables.
