Electrical
Adjustments
Electrical alignments Alignment conditions:
All electrical adjustments should be performed under the following conditions:
• Power supply voltage: 240V ±10%,50Hz ± 5%.
• Warm-up time: 10 minutes
• The voltages and oscillograms are measured in relation to the tuner earth.
• Test probe: Ri> 10M2; Ci <2,5 pF.
1. Adjustments on the large signal panel
1.1 95V/140V supply voltage
For 21” TV-sets
Connect a volmeter to the cathode of D6567. With the aid of R3532 adjust the power supply voltage to 95V ± 0,5V.
For sets > 21”
Connect a volmeter to the cathode of D6567. With the aid of R3559 adjust the power supply voltage to 140V ±1v.
1.2 VG2 adjustment
Connect a pattern generator displaying a full black picture. Switch the TV-set to the service default mode (see 7.4). Connect an oscilloscope to the picture tube cathodes for red, green and blue (pins 6, 8 and 11 of the picture tube socket). Set the oscilloscope to DC, 50V/div and 2 mS/div. Measure the DC level of the measur­ing pulses at the end of the frameblanking (see Fig. 7.1) Using the Vg2 potentiometer on the line transformer (bottom potentiometer) the measur­ing pulse with the highest level must be set to +160V ± 2V.
Fig. 7.1
1.3 Focusing
Is aligned using the focus potentiometer on the linetransformer (top potentiometer).
2. Alignments on the small signal panel
2.1 40.4 MHz IF filter
(only for sets with SECAM LL’ reception)
Using a signal generator (b.v. PM5326) and a capacitor of 5,6 pF supply a 40,4 MHz signal ton pin 17 of the tuner. Connect an oscilloscope to pin 1 of filter 1016. Switch on the set and set the system selection (installationmenu) to BG. Set L5117 for minimal amplitude. Remove the supplied signal.
2.2 AFC
Switch the set to service default mode (see 7.4). Using a pattern generator (e.g. PM5518) supply a signal on a frequency of 475,25 MHz. Align coil L51 14 for optimal picture quality.
2.3 Picture demodulator
(only for sets with SECAM LL’ reception)
Using a signal generator (eg. PM5326) supply a
32.95 MHz signal via a 5,6 pF capacitor to pin
17 of the tuner. Align the signal level of the generator so that the DC-voltage on pin 5 of the tuner is 5V. Switch on the set and set the system selection (installation
menu) to system LL’. Align capacitor C2106 for minimal voltage on pin 5 of the tuner. Remove the supplied signal.
2.4 RF-AGC
If the signal of a strong local transmitter is distorted, align the value for AX (AGC crosso­ver) in the service menu (see 7.4) until the picture is no longer distorted.
2.5 Audio demodulator (not for sets with LL’ and NICAM reception possibility)
Using a signal generator (eg. PM5326) supply a
38.9MHz signal via a 5,6 pF capacitor to pin 17 of the tuner. Connect an oscilloscope (2ms/div) to pin 12 of IC7033 (TDA3845). Align coil L5030 for minimal amplitude. Remove the supplied signal.
3. Adjustments in the service menu (see 7.4)
3.1 White balance
Alignment without a colour temperature meter Connect a pattern generator and select a white picture. Switch on the servicemenu (see 7.4) and using the keys go to the GD setting. Using the keys, set GD to 50. Go to
setting RD, and set it to 57. Go to setting BD, and set it to 45. If necessary change the settings for RD and BD for a correct white balance.
Alignment with a colour temperature meter Switch on the service menu (see 7.4) and go to the GD, RD and BD settings using the keys. Set all three values to 32 using the keys.
Connect a pattern generator and select a green field. put the probe onto the screen, and set the meter to NIT (cd/m2 ) measurement. Go to the GD adjustment and set it to:
• 21 : 350 NIT ± 10 NIT
• 25/28 black matrix : 270 NIT ± 10 NIT
• 25/28 Blackline-S : 300 NIT ± 10 NIT Now select a white picture and suing the RD
and BD alignments adjust for the following values:
x = 0.299
y = 0,308
3.2 Options Go to the service mode (see 7.4). The following
options can be selected using the keys, and
can be controlled
using the keys.
• NI : NICAM present (IC7353 = M5P3410)
• UO : UHF only (tuner = U944)
• LL : System secam LL’ possible (coil 5117 present).
• TT : Teletext available (IC7702 present)
• ET : East-european teletext.
• E2 : Second Euroconnector present.
3.3 Geometry adjustments.
Supply a geometry adjustment pattern. Go to the service menu (see 7.4). the following adjustments can be selected with the keys, and can be adjusted using the keys.
VP : Vertical Shift
Set this for the correct vertical position.
VA : Picture height
Set this for the correct picture height.
VL : Vertical linearity.
Set this so that the vertical centre of the picture is at the centre of the tube.
VS : Vertical S-correction
Set this so that the height of the squares in the top of the picture equal the height in the bottom of the picture.
HD : Horizontal shift.
Set this so that the horizontal centre of the picture is on the centre of the tube.
For sets with a screensize larger than 21”, the following alignments can be done as well. For 21” sets these alignments have no function.
HW : Horizontal Width
Align the picture width with this.
HP : East-west correction
Set this so that the vertical lines at the sides of the screen are straight.
HC : East-west corner-correction.
Set this so that the vertical lines are straight in the corners.
HT : Trapezium correction
Set this so that the vertical lines are as vertical as possible.

Service Notes
The contents of this service information:
• The power supply circuit diagram that is divided into two separate parts:
• 21” power supply circuit diagram
- power supply circuit diagram for 25” and 28”
• fault-finding tree for repairing the television because:
- the error register in the service menu is not filled in sets bearing code QG00 for the Netherlands and Italy. For all other countries the error registers in the service menus of sets bearing code QG03 and lower is not filled.
• Introduction of two new features, 16:9 module and WSSB (wide screen signalling bit detection) module, with accompanying copper track layout and spare parts list with accom­panying diagram.
Description of the new features in the MD1.1 TV set.
The WSSB enables the TV set to switch automatically to the various display formats (16:9 letterbox, 14:9 letterbox, 4:3) using signalling bits. The signalling bits are transmit­ted in line 23 of the video signal. IC7119 (TDA8366) is used to match the convergence to the various formats in cooperation with the 16:9 panel.
1. MD1.1 E 28” WideScreen
The information published in the Service Manual and SI MD1 .1 -E 95.01 is also valid for MD1 .1 E 28” WideScreen sets. However, there is some diversity in the spare parts list (See Table 1).
2. Microprocessors
The listed microprocessors (Table 1) can be used for “24” and “28” Widescreen MD1.1 E sets. When the µPs are used in a “28” WS set, the option “28” in the Service Alignment Menu should be set to “Y”. When the µPs are used in a 24” WS set, the option “28” should be set to “N”.“28 N” is the default value of these µPs after replacement.
3. Mechanics
The mechanical execution of the WideScreen sets (24” and 28”) differs from the other MD1 .1 E sets. Service positions and other mechanical intructions are described in the MD1 .2E Service section (Styling with top control and side input/ output).
