Proper
service and repair is important to the safe, reliable operation of all Philips equipment.
The service procedures recommended and described are effective methods of
performing service operations. Some of these service operations require the use
of tools specially designed for the purpose. The special tools should be used.
E8 chassis introduction
The
E8 series chassis is the Small Screen TV chassis produced by Philips Consumer
Electronics Company for the 1999-2000 model year. The E8 is used with 13, 19,
and 20 inch CRT’s. The E8 Tuning System features a 181 channel Tuning System
with On-Screen Display. The Tuning System uses two IC’s mounted on the main
chassis. It consists of a Microcomputer IC and Memory IC. The Microcomputer
communicates with the Memory IC, the Customer Keyboard, the Remote Receiver,
the U/V Tuner, the TV Signal Processor, the Stereo Decoder (optional), and the
Power On-Off circuitry. The Memory IC retains the settings for favourite stations, customer control settings, feature settings, and factory setup data.
The
chassis features a Very Large Scale Integration (VLSI) IC for TV Signal Processing.
This IC performs Video IF, Sound IF, AFT/AGC control, Horizontal Signal
Processing, Vertical Signal Processing, Horizontal/Vertical Synchronisation,
Chroma/Luminance Processing, and Video Switching between internal and external
inputs. On-Screen Graphics from the Microcomputer are placed on the main signal
within the TV Signal Processor. Automatic Volume Level (AVL) from the
Microcomputer is sent to the TV Signal
Processor (Mono Sets) and to the Stereo Module (DBX Stereo Sets via the I2C bus). AVL for Normal Stereo is switched by Pin 9 of the Microcomputer, 7600. The Mono version has a 1 watt audio amplifier. The Normal Stereo version has a 2x1 watt amplifier. The DBX Stereo version has a 2x3 watt amplifier. Latin American versions of this chassis may have a 2 or 3 watt Mono amplifier.

The
E8 chassis features a Switching Mode Power Supply. A ”HOT“ ground reference is
used in the primary side of the power supply. ”COLD“ (signal) ground is used
from the secondary of the power supply and throughout the rest of the chassis.
An isolation transformer is required when doing service on any chassis.
Power Supply Voltages
Chassis service adjustments
1. The
E8 chassis incorporates a ”hot“ ground system. Always use a separate isolation
transformer when applying power to the exposed chassis.
All
service adjustments are ”hot“ voltage wise. For maximum safety, ensure the use
of properly insulated tools.
2. Refer to the E8 Main Chassis Printed Circuit Board for location of test points and adjustable components.
3. Grid Locations (Ex.: D-3) next to the reference numbers for components refer to the Main Chassis Printed Circuit Board.

Service Mode
There
are three service modes used in the E8 chassis. They are:
a. SDM - Service Default Mode
b. SAM - Service Alignment Mode
c. CSM - Customer Service Mode
2. The Service Default Mode (SDM) is a technical aid for the service technician. It is used for setting of options, reading error codes, and erasing error codes. This mode displays the Run Timer, Software Version, and current option settings. Service Default Mode (SDM) also establishes a fixed, repeatable setting of controls to allow measurements to be made. On screen display is kept at a minimum to reduce the cluttering of wave forms with unwanted information.
3. The Service Alignment Mode (SAM) is used to make tuning adjustments, align the white tone, adjust the picture geometry, and make sound adjustments.
4. The Customer Service Mode shows error codes and information on the TV operation settings. The service person can instruct the customer to enter CSM by telephone and read off the information displayed. This helps the servicer to diagnose problems and failures in the TV set before making a service call.
5. When in a service mode, "SDM" (for Service Default Mode) or ”SAM“ (for Service Alignment Mode) or ”CSM“ (for Customer Service Mode) will be displayed (in green) in the top right corner of the screen. All other On Screen Display (except highlighted items in SDM or SAM) will be in red.
6. It will be memorised in the EEPROM that the TV set is in SDM or SAM. This is necessary because the TV must show up in SDM or SAM again after an ac power interrupt.
7. When the television is in SAM or SDM, all normal features (such as volume control and direct channel access) are available.
a. SDM - Service Default Mode
b. SAM - Service Alignment Mode
c. CSM - Customer Service Mode

7. When the television is in SAM or SDM, all normal features (such as volume control and direct channel access) are available.
EEPROM Replacement or Defective EEPROM
After replacing a EEPROM (or with a defective/no EEPROM) default settings will be used that enable the set to start up and that allow access to the Service Default Mode and Service Alignment Mode.
After replacing a EEPROM (or with a defective/no EEPROM) default settings will be used that enable the set to start up and that allow access to the Service Default Mode and Service Alignment Mode.
Service unfriendly modes
In the service modes, a number of modes/features are ignored since they interfere with diagnosing or repairing a set. These are ”service unfriendly modes.“ ”Ignoring“ means that the event that is triggered is not executed; the setting remains unchanged (Example: Timer OFF: 8:00 PM; the set will not switch OFF in service mode at 8:00PM, but the setting will remain).
The service unfriendly modes are:
(Sleep) timer
Blue mute
Auto switch off (when there is no video signal identified)
Hotel or hospital mode
Smart lock or blocking by V-chip
Skipping and/or blanking of ”Not Favorite“ channels
Automatic storing of Personal Preset settings
Automatic user menu time-out (menu switches back or OFF automatically)

Explanation of Display
Run Timer
The run timer counts the normal operation hours, not the standby hours. The actual value of the run timer is displayed in SDM and CSM. The run timer displays hours in hexadecimal format. This display will increment based on the amount of time the set has been on. The timer will also be incremented one hour each time the set is turned on.

Software Identification, Cluster, and Version
The software identification, cluster, and version will be shown in the service main menu display.
These numbers consist of the last part of the customer identification printed on the IC package; the screen will show ”AAABBC-X.Y“. (Example: L90US1 1.2)
AAA is the engineering project name (Ex: L90 = L9.0).
BB is a function specification indicating specific functionality or a region (Ex: US). Processors with the same engineering project name and function name are interchangeable, except for the languages they support.
C is the language cluster number within the ”BB“ software version (Ex: 1 = English/Spanish/French)
X is the main version number (Ex: 1)
Y is the sub version number (Ex: 2)
the main version number is updated with a major change of specification (incompatible with the previous software version)
the sub version number is updated with a minor change (backwards compatible with the previous versions)
if the main version number changes, the new version number is written in the EEPROM
if the main version number changes, the default settings are loaded
if the sub version number changes, the new version number is written in the EEPROM
if the EEPROM is fresh, the software identification, version and cluster will be written to EEPROM
Note: a new micro controller is considered to be compatible if it works instead of the old software and the functionality is not significantly changed.

Error Buffer
Error codes are required to indicate failures in the television. For intermittent complaints, always check the error buffer. A unique error code is available for:
activated protection (error codes 1, 2, and 3)
failing I2C device
general I2C error
RAM failure (e.g. internal RAM of microprocessor (IC 7600) )
Other error codes are
Signal processor (IC 7250) start-up error.
