5.1 Test Points
This chassis is equipped with test points in the service printing.
In the schematics test points are identified with a rectangle box
around Fxxx or Ixxx. These test points are specifically
mentioned in the “Test Point Overview” as “half moons” with a
dot in the center.
Perform measurements under the following conditions:
• Television set in Service Default Alignment Mode.
• Video input: Color bar signal.
• Audio input: 3 kHz left channel, 1 kHz right channel.
5.2 Service Modes
Service Default Alignment Mode (SDAM) offers several
features for the service technician, while the Customer Service
Mode (CSM) is used for communication between the call
center and the customer. For the TV setup main menu, please
refer to the DFU.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version readout for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").
5.2.1 Service Default Alignment Mode (SDAM)
Purpose
• To change option settings.
• To create a predefined setting to get the same
measurement results as given in this manual.
• To display / clear the error code buffer when leaving SDAM
with “standby” key on remote control.
• To override SW protections.
• To perform alignments.
• To start the blinking LED procedure.
Specifications
• Tuning frequency:
– 61.25 MHz (channel 3)
• Colour system:
–NTSC
• All picture settings at 50 % (brightness, color contrast,
hue).
• Bass, treble and balance at 50 %; volume at 25 %.
• All service-unfriendly modes (if present) are disabled, like:
– (sleep) timer,
– child/parental lock,
– blue mute,
– hotel/hospitality mode
– auto switch-off (when no IDENT video signal is
received for 15 minutes),
– skip / blank of non-favourite presets / channels,
– auto store of personal presets,
– auto user menu time-out.
• Operation hours counter.
• Software version.
• Option settings.
• Error buffer reading and erasing.
• Software alignments.
How to Enter SDAM
To enter SDAM, use one of the following methods:
• Switch the optional RC2573GR remote controll to Setup
mode, and press the following key sequence on the remote
control transmitter: “062596" directly followed by the
M(enu) button (do not allow the display to time out between
entries while keying the sequence).
• Or via ComPair.
• Or Short circuit the SDAM jumper on the mono carrier (see
Chapter 7: Layout Mono Carrier: Top side, item 9252 in cel
C5) and apply AC power. Then press the power button
(remove the short circuit after start-up).
Caution: Entering SDAM by short-circuiting the SDAM jumper
will override the +8V-protection. Do this only for a short period.
When doing this, the service-technician must know exactly
what he is doing, as it could lead to damaging the set.
After entering SDAM, the following screen is visible, with “S” in
the upper right corner of the screen to indicate that the
television is in Service Default Alignment Mode.

1. LLLL
This is the operation hours counter. It counts the normal
operation hours, not the standby hours.
2. AAAABC-X.Y
This is the software identification of the main micro
controller:
– A = the project name (L04H).
– B = the region: E= Europe, A= Asia Pacific, U= NAFTA,
L= LATAM.
– C = the feature and language
– X = the main software version number.
– Y = the sub software version number.
3. S
Indication of the actual mode. S= SDAM= Service Default
Alignment mode.
4. Error buffer
Five errors possible.
