Index of this chapter:
a.. General Alignment Conditions
b.. Hardware Alignments
c.. Software Alignments and Settings
Note: The Service Default Alignment Mode (SDAM) is described in the "Service
Modes, Error Codes and Fault Finding" section. SDAM menu navigation is
performed by using the MENU UP, MENU DOWN, MENU LEFT, and MENU RIGHT keys of
the remote control transmitter.
General Alignment Conditions
Perform all electrical adjustments under the following conditions:
a.. AC voltage and frequency: 110 V (± 10 %), 60 Hz (± 5 %).
b.. Connect the television set to the AC power via an isolation
transformer.
c.. Allow the television set to warm up for approximately 20 minutes.
d.. Measure the voltages and waveforms in relation to chassis ground (with
the exception of the voltages on the primary side of the power supply).
Never use heatsinks as ground.
e.. Test probe: Ri > 10 MOhm; Ci < 2.5 pF.
f.. Use an isolated trimmer/screwdriver to perform the alignments.

pulse' and the other being the 'white drive pulse'. Choose the one with the
lowest value; this is the 'cut off pulse'.
t.. Select the cathode with the highest VDC value for the alignment.

Software Alignments and Settings
The following options are performed in the Service Default Alignment Mode
(SDAM). SDAM is described in the 'Service Modes, Error Codes and Fault
Finding' section.
The following alignments are explained:
a.. OPTIONS
b.. TUNER
c.. WHITE TONE
d.. GEOMETRY
e.. AUDIO
Options
Options are used to control the presence or absence of certain features and
hardware.
How to change an Option Byte
An Option Byte represents a number of different options. Changing these
bytes directly makes it possible to set all options very quickly. All
options are controlled via seven option bytes.
Note: Each option byte controls several features of the television set;
therefore, before changing option byte information, it is important to
record the current option byte values. This ensures that the television
features can be restored to the original settings, if necessary.
a.. To enter SDAM, press the following key sequence on the remote control
transmitter: 0 6 2 5 9 6 directly followed by the MENU button (do not allow
the display to time out between entries while keying the sequence).
b.. Use the MENU UP/DOWN keys to highlight the OPTIONS sub menu.
c.. Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu.
d.. In the OPTIONS sub menu, press the MENU UP/DOWN keys to select 'OP 1'
through 'OP 7'.
e.. Use the number keys on the remote control transmitter to enter a new
value for the selected option byte. The value must be entered as a
three-digit value (for example, '4' would be entered as '0 0 4').
f.. The selected value must be between '0' and '255'.
g.. When all desired changes to the option bytes are made, press the MENU
button to return to the top level SDAM menu. This will save changes to the
option byte settings.
h.. To ensure the option byte changes take effect: Turn the television set
OFF by using the POWER button on the remote control transmitter or the local
keyboard. Disconnect the television set from AC power for at least ten
seconds. Reconnect the television set to AC power. Turn the television set
ON by using the POWER button on the remote control transmitter or the local
keyboard.
Figure: Options menu
How to change iTV Option Bytes
An Option Byte represents a number of different options. Changing these
bytes directly makes it possible to set all options very quickly. All
options are controlled via five option bytes.
Note: Each option byte controls several features of the television set;
therefore, before changing option byte information, it is important to
record the current option byte values. This ensures that the television
features can be restored to the original settings, if necessary.
a.. To enter SDM, you must use a Philips ITV commercial setup transmitter
(such as the RC2573GR or the RG4172BK). Use the following method to enter
SDM:
First, place the setup remote in setup mode. To place the the RG4172BK in
setup mode, press TV SETUP; to place the the RC2573GR in setup mode, set the
switch to the TV SETUP position. Then press the following key sequence on
the remote control transmitter: '0 6 2 5 9 6' directly followed by the
'MENU' button (do not allow the display to time out between entries while
keying the sequence).
b.. Use the MENU UP/DOWN keys to scroll through the OPTIONS until you
reach OB1 through OB5.
c.. Use the number keys on the remote control transmitter to enter a new
value for the selected option byte. The value must be entered as a
three-digit value (for example, '4' would be entered as '0 0 4').
d.. The selected value must be between '0' and '255'.
e.. When all desired changes to the option bytes are made, press the MENU
button to return to the top level SDM menu. This will save changes to the
option byte settings.
f.. To ensure the option byte changes take effect: Turn the television set
OFF by using the POWER button on the remote control transmitter or the local
keyboard. Disconnect the television set from AC power for at least ten
seconds. Reconnect the television set to AC power. Turn the television set
ON by using the POWER button on the remote control transmitter or the local
keyboard.

on the screen.
b.. Horizontal Parallelogram (HP). Set Horizontal Parallelogram to prevent
the picture from slanting to one side.
c.. Horizontal Bow (HB). Set Horizontal Bow to prevent the top and bottom
of picture from bending to the sides.
d.. East West Width (EWW). Select East-West Width and align the picture
width until the complete test pattern is visible.
e.. East West Parabola (EWP). Select East-West Parabola and align the
vertical sides until the sides are straightened.
f.. Upper Corner Parabola (UCP). Select Upper Corner Parabola to
straighten the top of the vertical lines at the sides.
g.. Lower Corner Parabola (LCP). Select Lower Corner Parabola to
straighten the bottom of the vertical lines at the sides.
h.. East West Trapezium (EWT). Align straight vertical lines in the middle
of the screen.
Vertical Amplitude and Position:
Figure: ertical alignment menu
a.. Vertical Amplitude (VAM). Aligns the height of the picture (other
vertical alignments are NOT compensated).
b.. Vertical slope (VSL). Aligns the picture so the proportions are the
same at the top and botton of the screen.This alignment must be performed
first, before all other vertical alignments. Turning SBL 'on' will assist in
performing this alignment.
c.. Service blanking (SBL). Turns the blanking of the lower half of the
screen 'on' or 'off' (to be used in combination with the vertical slope
alignment).
d.. Vertical S-Correction (VSC). Aligns the vertical linearity, so that
the vertical intervals of the grid-patterns are the same over the entire
height of the screen.
e.. Vertical Shift (VSH). Aligns the vertical center of the picture to the
vertical center of the CRT. After performing this alignment, it may be
necessary to perform the VAM alignment again.
f.. Vertical Zoom (VX). Adjusts the picture height.
g.. Delta Horizontal Shift 60 Hz (H60).
h.. Delta Vertical Amplitude 60 Hz (V60).
Methods of adjustment
a.. Select Service Blanking (SBL) and set it to 1. The lower half of the
picture will be blanked.
b.. Press the MENU UP/DOWN buttons to select Vertical Slope (VSL).
c.. Align VSL to start the blanking exactly at the horizontal white line
at the center of the test circle (align the bottom of the screen so that
castellations just disappear).
d.. Press the MENU UP/DOWN buttons to select SBL and set it back to 0. The
full picture reappears.
e.. Select Vertical Amplitude (VAM) and align the picture height to
approximately 13.0 - 13.1 blocks (align the top of the screen so that
castellations just disappear).
f.. Select Vertical Shift (VSH) and align for vertical centering of the
picture on the screen.
Repeat the last two steps if necessary.
