Electrical Adjustments

Alignments - S8 Chassis
Index of this chapter:
1. General Alignment Conditions
2. Commercial Models SDAM Entry
3. Hardware Alignments
4. 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:
•AC voltage and frequency: 110V (± 10 %), 60Hz (± 5 %).
•Connect the television set to the AC power via an isolation transformer.
•Allow the television set to warm up for approximately20 minutes.
•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.
•Test probe: Ri > 10MO; Ci < 2.5pF.
•Use an isolated trimmer/screwdriver to perform the alignments.
Service Default Alignment Mode (SDAM) Entry for
Commercial Models
Note: For commercial models, a master setup remote control is required in order to
access the Service Default Alignment Mode (SDAM).
1. Use the master setup remote control to identify the television’s operational mode
(either “consumer” or “commercial”). Place the master setup remote control in
setup mode by pressing the TV SETUP key.
2. Press the RECALL key. Information similar to the following will be displayed.

3. To change the television’s mode, ensure the master setup remote control is in
setup mode, then press the 0-2-4-9-9-5-MENU keys in order, without permitting
the display to time out while entering the key sequence.
N
ote: If the operational mode is changed, the television must be turned off and then back on to
complete the mode change. When the television is in consumer mode, do not use the master setup
remote control to activate commercial mode features.
4. When the television is in commercial mode, the Institutional Television Menu may
be accessed by pressing the MENU button. Though the specific items in the menu
will vary, information similar to the following will be displayed.

through OP 7.
5. 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").
6. The selected value must be between 0 and 255.
7. 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.
8. To ensure the option byte changes take effect:

•Horizontal Bow(HB). Aligns straight horizontal lines at the top and the bottom of
the screen; horizontal rotation around the center.
•Horizontal Shift(HSH). Aligns the horizontal center of the picture to the
horizontal center of the CRT.

Figure: Vertical geometry alignment screens
Vertical:
•Vertical slope (VSL). Aligns the picture so the proportions are the same at the
top and bottom of the screen. This alignment must be performed first, before all
other vertical alignments. Turning SBL ON will assist in performing this
alignment.
•Vertical Amplitude(VAM). Aligns the height of the picture (other vertical
alignments are NOT compensated).
•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.
•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.
•Vertical Zoom(VX). Adjusts picture height.
•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).
