Notes:
•Only information that is related to the iTV module, is
published in this manual. For the other information, see the
relevant chassis manual (order code on front page).
•Figures below can deviate slightly from the actual situation,
due to the different set executions.
•Follow the disassembling instructions in described order.
Note: To diagnose the set with ComPair it is not needed to
open the set entirely.
To access the ComPair connector, proceed with the following:
1. Manually unlock and remove the cover cap.
2. Remove the tape shielding that covers the ComPair
connector (1).
Note: Make sure that both the ComPair connector and the
UART connector are shielded off with a piece of insulating tape
after repair for ESD reasons. Place this tape over the holes in
the rear cover of the set.
4.1Service Position
4.1.1 Foam Bars
Figure 4-2 Foam bars
The foam bars (order code 3122 785 90580) can be used for
all types and sizes of Flat TVs. By laying the plasma or LCD TV
flat on the (ESD protective) foam bars, a stable situation is
created to perform measurements and alignments. By placing
a mirror under the TV, you can easily monitor the screen.

4.3.1 Rear Cover
Warning: Disconnect the mains power cord before you remove
the rear cover.
1. Remove the screws that secure the rear cover.
2. Lift the rear cover from the cabinet cautiously. Make sure
that wires and other internal components are not damaged
during cover removal.

2. Release the two fixation clamps [2] and lift the panel out of
the bracket.
4.4Set Re-assembly
To re-assemble the whole set, execute all processes in reverse
order.
Notes:
•While re-assembling, make sure that all cables are placed
and connected in their original positions. See Figure "Cable
dressing". Also make sure that the anti-static copper foils
are not damaged and that they make good electrical
contact with the metal frame. Be careful with the fragile
LVDS cable.

Block Diagrams, Test Point Overviews, and Waveforms
•Only information that is related to the iTV module, is
published in this manual. For the other information, see the
relevant chassis manual (order code on front page).
•Figures below can deviate slightly from the actual situation,
due to the different set executions.
•The Service Default Mode (SDM) and Service Alignment
Mode (SAM) are described in chapter 5. Menu navigation
is done with the Cursor Up, Down, Left or Right keys of the
remote control transmitter.
8.1General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
Mains voltage and frequency: 100-240 V / 50/60 Hz.
Allow the set to warm up for approximately 10 minutes.
Test probe: Ri > 10 MΩ; Ci < 2.5 pF.
8.2Hardware Alignments
There are no hardware alignments foreseen for the LCD-TV.
8.3Software Alignments
With the software alignments of the Service Alignment Mode
(SAM) the geometry, white tone and tuner (IF) can be aligned.
To store the data: Use the RC button Menu to switch to the
main menu and next, switch to ‘Stand-by’ mode.
8.3.1Options
Options OP1...OP7 in the SAM menu can be used for quickly
restoring features or settings of the Hercules part of the TV set
to their original default factory values (8 groups of 8 features/
settings each). When the decimal value of one option byte
OP1...OP7 is changed (see the first table below) then a group
of 8 bits, representing 8 Hercules options or features, is
changed as well (see the second table below for a detailed
description of the features or settings that are changed).
The second table shows which option byte (OP1...OP7)
represents which group of 8 option bits. Each bit (0...7)
switches a particular Hercules feature or setting ON or OFF,
depending on its value (1 or 0).
It is also possible to change the features or settings mentioned
in the second table directly at bit level, by means of the NVM
Editor in the SAM menu. In the NVM Editor, first the correct
NVM address (ADR) has to be entered, then the correct value
(VAL, 1 or 0) for each bit (see second table), and finally the
settings have to be stored (STORE). For quickly restoring the
Hercules part of the TV set to its original factory settings,
however, it is more convenient to simply enter the default
factory settings OP1...OP7 that are given in the first table
below. How to do this, is described in the next paragraph.
How to Change Options at Bit Level
If you wish to know which features or settings of the Hercules
are changed via OP1...OP7, or if you want to change each
option or feature bit by bit, use the more detailed table below.

The table below shows a number of important NVM settings (in
decimal values) used for each TV model. Be sure to use the
correct editor in the SAM menu (NVM Editor), because this one
is used for the Hercules NVM, and the SC NVM Editor for the
SCALER (SC) part of the TV set.

Caution:
•Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
•Do not change the Scaler NVM settings below address
320 (dec), as this will hamper the DVI functionality of
the TV set!
•Always write down the existing NVM settings, before
changing the settings. This will enable you to return to
the original settings, if the new settings turn out to be
incorrect.

If the i-Board is directly replaced by a new off-shelf module
(already programmed with platform software), the correct iTV
model still must be programmed via below sequences to get to
the correct model type with its I/O configurations.
Alignments
EN 27LC4.1HE AB8.
1. Put the iTV remote control (e.g. RC2573) in setup mode.
2. Push a number on the remote control to switch “on” the TV.
3. Push the RECALL button.
4. Check the model number, listed in line 05.
If it is correct, the setting is done.
If the number is incorrect, continue with the next point.
5. Key in “042420”, immediately followed by “M”.
You now enter SDM.
6. Select and activate NVM EDIT mode.
7. Key in address “0022” (hex).
8. Push ARROW DOWN to activate the “Value” line.
9. From the Diversity table read the diversity code that
belongs to the type of TV set you are adjusting. Enter that
number in the “Value” line.
10. Select STORE to put the new value in the NVM.
11. Push the POWER button to switch “off” the TV set.
12. Pull the mains plug.
13. Reconnect the mains plug after a few seconds.
14. The new setting is now active.

9.1Introduction
The LC4.1 LCD iTV is a Hotel TV based on the LC4.1 chassis.
For a detailed circuit description, please use that specific
manual (order code on front page). The iTV specific board in
this chassis (i-Board) is for Service a “black box”, and therefore
must be replaced completely when defective (board swap).
