2. HOW TO ENTER SERVICE MODE AND ADJUST DATA VALUES TO PHILIPS LCD TVS

Service Modes
Service Default mode (SDM) and Service Alignment Mode (SAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call centre and the customer.  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.

Service Default Mode (SDM)
Purpose
* To create a predefined setting for measurements to be made.
* To override software protections.
* To start the blinking LED procedure.
* To inspect the error buffer.
* To check the life timer

Specifications
# Tuning frequency: 475.25 MHz
# Color system: PAL-BG.
# 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. The service unfriendly modes are:

> Timer / Sleep timer.
> Child / parental lock.
> Blue mute.
> Hotel / hospital mode.
> Auto shut off (when no “IDENT” video signal is received for 15 minutes).
> Skipping of non-favorite presets / channels.
> Auto-storage of personal presets.
> Auto user menu time-out.
> Auto Volume Leveling (AVL).

How to enter
To enter SDM, use one of the following methods:
 Press the following key sequence on the remote control transmitter: “062596” directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence).
 Short "Service" jumpers on the small signal board during cold start and apply mains (see Figure "Service jumpers").  Then press the mains button (remove the short after startup).
Caution: Entering SDM by shorting "Service" jumpers will override the +5V-protection. Do this only for a short period.  When doing this, the service-technician must know exactly what he is doing, as it could damage the television set.

SERVICE JUMPERS

After entering SDM, the following screen is visible, with SDM in the upper right corner of the screen to indicate that the television is in Service Default Mode.

How to navigate

Use one of the following methods:
 * When you press the MENU button on the remote control, the set will switch on the normal user menu in the SDM mode.
* On the TV, press and hold the VOLUME DOWN and press the CHANNEL DOWN for a few seconds, to switch from SDM to SAM and reverse.

How to Exit
Switch the set to STANDBY by pressing the mains button on the remote control transmitter or the television set.  If you turn the television set off by removing the mains (i.e., unplugging the television) without using the mains button, the television set will remain in SDM when mains is re-applied, and the error buffer is not cleared.

Service Alignment Mode (SAM)
Purpose
• To change option settings.
• To display / clear the error code buffer.
• To perform alignments.
Specifications
• Operation hours counter (maximum five digits displayed).
• Software version, Error codes, and Option settings display.
• Error buffer clearing.
• Option settings.
• AKB switching.
• Software alignments (Tuner, White Tone, Geometry & Audio).
• NVM Editor.
• ComPair Mode switching.

How to Enter
To enter SAM, use one of the following methods:
• Press the following key sequence on the remote control transmitter: “062596" directly followed by the OSD/STATUS button (do not allow the display to time out between entries while keying the sequence).
• Or via ComPair.

After entering SAM, the following screen is visible, with SAM in the upper right corner of the screen to indicate that the television is in Service Alignment Mode.

Menu Explanation

Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and information on the TV’s operation settings. The call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps the call centre to diagnose problems and failures in the TV set before making a service call.
The CSM is a read-only mode; therefore, modifications are not possible in this mode.

How to Enter
To enter CSM, press the following key sequence on the remote control transmitter: “123654” (do not allow the display to time out between entries while keying the sequence).  Upon entering the Customer Service Mode, the following screen will appear:

Menu Explanation
1. Indication of the decimal value of the operation hours counter, Software identification of the main microprocessor
(see "Service Default or Alignment Mode" for an explanation), and the service mode (CSM= Customer Service Mode).
2. Displays the last five errors detected in the error code buffer.
3. Displays the option bytes.
4. Displays the type number version of the set.
5. Reserved item for P3C call centers (AKBS stands for
Advanced Knowledge Base System).
