4. Service Modes

4.1 Service Modes

The Service Mode feature is split into following parts:

 Factory Mode.  Customer Service Mode (CSM).SAM and the Factory mode offer features, which can be used by the Service engineer to repair/align a TV set.

The CSM is a Service Mode that can be enabled by the consumer. The CSM displays diagnosis information, which the customer can forward to the dealer or call centre. In CSM mode, “CSM”, is displayed in the top right corner of the screen. The information provided in CSM and the purpose of CSM is to:

 Increase the home repair hit rate.  Decrease the number of nuisance calls.  Solved customers’ problem without home visit.

Note: For the new model range, a new remote control (RC) is used with some renamed buttons. This has an impact on the activation of the Service modes. For instance the old “MENU” button is now called “HOME” (or is indicated by a “house” icon).

4.2 Factory mode:

Purpose

 To perform extended alignments.

Specifications

 Displaying and or changing Panel ID information.  Displaying and or changing Tuner ID information.  Error buffer clearing.  Various software alignment settings.  Testpattern displaying.  Public Broadcasting Service password Reset.  etc.

How to Activate the Factory mode

To activate the Factory mode, use the following method:

 Press the following key sequence on the remote control transmitter: from the “menu/ho me” press “1999”, directly followed by the

“Back/Return” button. Do not allow the display to time out between entries while keying the sequence.

After entering the Factory mode, we can see many items displayed, use the UP/D OWN keys to display the next/previous menu items

Factory mode overview

How to Exit the Factory mode

Use one of the following methods:

 Select EXIT_FACTORY from the menu and press the “OK” button.

Note: When the TV is switched “off” by a power interrupt, or normal switch to “stand-by” while in the factory mode, the TV will show up in “normal operation mode” as soon as the power is supplied again. The error buffer will not be cleared.

4.4 Customer Service Mode (CSM)

Purpose

The Customer Service Mode shows error codes and information on the TVs 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.

Specifications

 Ignore “Service unfriendly modes”.  Line number for every line (to make CSM language independent).  Set the screen mode to full screen (all contents on screen is visible).  After leaving the Customer Service Mode, the original settings are restored.  Possibility to use “CH+” or “CH-” for channel surfing, or enter the specific channel number on the RC.

How to Activate CSM

To activate CSM, press the following key sequence on a standard remote control transmitter: “456987” (do not allow the display to time out between entries while keying the sequence). After entering the Customer Service Mode, the following items are displayed. use the Right/Left keys to display the next/previous menu items

Note: Activation of the CSM is only possible if there is no (user) menu on the screen!

CSM Overview

How to Navigate

By means of the “CURSOR-DOWN/UP” knob (or the scroll wheel) on the RC-transmitter, can be navigated through the menus.

How to Exit CSM

To exit CSM, use one of the following methods.

 Press the MENU/HOME button on the remote control transmitter.  Press the POWER button on the remote control transmitter.  Press the POWER button on the television set.

6.2 Power Supply

Power architecture of this platform.

6.2.1 Power Supply Unit

All power supplies are a black box for Service. When defective, a new board must be ordered and the defective one must be returned, unless the main fuse of the board is broken. Always replace a defective fuse with one with the correct specifications! This part is available in the regular market. Consult the Philips Service web portal for the order codes of the boards. Important delta’s with the platform are:

• New power architecture for LED backlight

• “Boost”-signal is now a PWM-signal + continuous variable

The control signals are:

• PS-ON

• Lamp “on/off”

• DIM (PWM) (not for PSDL)

In this manual, no detailed information is available because of design protection issues.

• +12 output (on-mode)

• +12V_audio (audio AMP power)

• Output to the display; in case of

- IPB: High voltage to the LCD panel

- PSL and PSLS (LED-driver outputs)

- PSDL (high frequent) AC-current.

6.2.2 Diversity

The diversity in power supply units is mainly determined by the diversity in displays. The following displays can be distinguished:

• CCFL/EEFL backlight: power panel is conventional IPB

• LED backlight:

- side-view LED without scanning: PSL power panel
