IMPORTANT SAFETY NOTICE Proper service and repair is important to the safe, reliable operation of all Philips Consumer Electronics Company** Equipment. The service procedures recommended by Philips and described in this service manual are effective methods of performing service operations. Some of these service operations require the use of tools specially designed for the purpose.
FIRE AND SHOCK HAZARD 1. Be sure all components are positioned in such a way as to avoid the possibility of adjacent component shorts. This is especially important on those chassis which are transported to and from the service shop. 2.
LEAKAGE CURRENT COLD CHECK 1. Unplug the ac line cord and connect a jumper between the two prongs of the plug. 2. Turn on the power switch. 3. Measure the resistance value between the jumpered ac plug and all exposed cabinet parts of the receiver, such as screw heads, antennas, and control shafts.
TV SAFETY NOTES SAFETY CHECKS After the original service problem has been corrected, a complete safety check should be made. Be sure to check over the entire set, not just the areas where you have worked. Some previous servicer may have left an unsafe condition, which could be unknowingly passed on to your customer.
The use of a substitute part which does not have the same safety characteristics as the Philips recommended replacement part shown in this service manual may create shock, fire, or other hazards.
PREVENTION OF ELECTROSTATIC DISCHARGE (ESD) Some semiconductor solid state devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices, Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD).

PRACTICAL SERVICE PRECAUTIONS IT MAKES SENSE TO AVOID EXPOSURE TO ELECTRICAL SHOCK. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard. ALWAYS RESPECT VOLTAGES. While some may not be dangerous in themselves, they can cause unexpected reactions –...

E8 CHASSIS SERVICE ADJUSTMENTS REQUIRED TOOLS FOR SERVICING Isolation Transformer Multimeter Oscilloscope High Voltage (100:1) Oscilloscope Probe Sencore VG91 Universal Video Generator Caution: The E8 chassis incorporates a ”hot“ ground system. Always use a separate isolation transformer when applying power to the exposed chassis. Service Adjustment Notes: Unless Otherwise Specified: 1.
Service Mode Introduction 1. There are three service modes used in the E8 chassis. They are: SDM - Service Default Mode SAM - Service Alignment Mode 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.
Page 36
Service Default Mode (SDM) 1. The Service Default Mode (SDM), set the option codes and bytes of the set, and display the error codes (the Power LED begins blinking procedure for error code display, if errors are detected). SDM also overrides software protections.
10. To exit the Service Default Mode and erase the error codes, turn the unit off with the Power button on the remote control, then unplug the ac cord. 11. To exit the Service Default Mode and save the error codes, unplug the ac cord to turn off the set. When the set is turned on again, the Service Default Mode will still be active.
Page 38
EEPROM check-sum error The last five errors, remembered in the EEPROM, are shown in the service menu. This is called the error buffer. The error that is found last is displayed on the left, except when protection (1 to 3) is active. Errors 1, 2, and 3 are often shown at the right of the error buffer display whenever they are detected.
Reading Error Codes Error codes are displayed in the following ways: 1. By SDM display or CSM display 2. By blinking Power LED 1. If the on screen display is working, enter SDM or CSM and read the error buffer display. 2.

Service Alignment Mode (SAM) 1. The Service Alignment Mode (SAM) is used to make tuning adjustments, align the white tone, adjust the picture geometry, and make sound adjustments. 2. To enter the Service Alignment Mode (SAM), press the following key sequence on the remote control transmitter: 0-6-2-5-9-6-Status Do not allow the display to time out between entries while keying the sequence.
6. To change the value of a highlighted SAM menu item (AKB or VSD), use the Menu Left or Menu Right keys on the remote control. 7. To enter a highlighted SAM sub menu, use the Menu Left or Menu Right keys. After entering the sub menu, use the Menu Up or Menu Down to select an item within the sub menu.
Tuner sub menu The tuner sub menu contains the following items: IF-PLL AFA and AFB The items AFA and AFB cannot be selected, they are for monitoring purposes only. The item values are stored in EEPROM if this sub menu is left. A sample display of the Tuner sub menu is shown below.
Page 48
AGC Takeover Point (AGC): 1. Enter the Service Alignment Mode (SAM) by pressing the following key sequence on the remote control transmitter: 0-6-2-5-9-6-Status Do not allow the display to time out between entries while keying the sequence. 2. From the top level SAM menu, use the Menu Up/Down keys to highlight the Tuner sub menu. 3.

Geometry sub menu OSD is kept to a minimum in this sub menu in order to make picture geometry adjustments possible. The item values are stored in EEPROM if this sub menu is left. The value of item Service Blanking (SBL) is not stored in EEPROM, and it is set to OFF when the geometry sub menu is exited.
Geometry Adjustments: Notes: 1. The following Geometry adjustments were performed with a Sencore VG91 Universal Video Generator. 2. Set the VG91 Generator as follows: STD TV Ch. 3, RF-IF Range set to HI, RF-IF Level set to NORMAL (1), Video Pattern = Raster, R-G-B raster controls OFF, crosshatch or center cross pattern as required. 3.
Page 52
Horizontal Shift (HSH): Note: This adjustment centers the video on the raster. It does not move the raster. 1. Enter the Service Alignment Mode (SAM) by pressing the following key sequence on the remote control transmitter: 0-6-2-5-9-6-Status Do not allow the display to time out between entries while keying the sequence. 2.
Service Blanking (SBL): Service Blanking provides a straight cutoff line in the center of the raster. It is useful when centering the raster. It can also be used in adjusting the yoke and setting vertical size and linearity. 1. Enter the Service Alignment Mode (SAM) by pressing the following key sequence on the remote control transmitter: 0-6-2-5-9-6-Status Do not allow the display to time out between entries while keying the sequence.
Audio Adjustment: Attack Time at AVL (AT): 1. Enter the Service Alignment Mode (SAM) by pressing the following key sequence on the remote control transmitter: 0-6-2-5-9-6-Status Do not allow the display to time out between entries while keying the sequence. 2.

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.
SIGNAL FLOW The incoming TV RF signal is applied to the U/V Tuner via the Antenna and RF input. The 45.75MHz IF signal is developed within the U/V Tuner, then amplified by an IF Preamplifier located inside the Tuner. The amplified IF signal is sent from Pins 10 and 11 of the U/V Tuner to the SAW filter, 1003.
Page 63
Amplifier 7954 or 7953 by a control line from the Microcomputer 7600 Pin 2. Volume for the Normal Stereo is controlled in the Stereo Module by a control line from the Microcomputer 7600 Pin 2. Volume control for the DBX Stereo is controlled in the Stereo Module by the Microcomputer via the I 2 C bus. Composite Video from Pin 6 of 7250 is buffered by 7266 and sent to 1200, a 4.5MHz trap, to remove any sound.
Page 64
E8 CHASSIS POWER SUPPLY BLOCK When a 120Vac source is connected to the E8 chassis, approximately 160Vdc is developed by the bridge rectifier circuit. The 160 volts dc goes through 5545 to the FET switch. The start voltage for the switching mode power supply is taken from the hot leg of the input ac.
SCHEMATIC NOTES: UNLESS OTHERWISE SPECIFIED: ALL VOLTAGES AND WAVEFORMS WERE TAKEN UNDER THE FOLLOWING CONDITIONS: LINE VOLTAGE MAINTAINED AT 120VAC, 60Hz VIA AN ISOLATION TRANSFORMER. PLACE THE TELEVISION SET IN SDM (SERVICE DEFAULT MODE). TO ENTER SDM, PRESS 0-6-2-5-9-6-MENU ON THE REMOTE CONTROL. ALL VOLTAGES WERE TAKEN FROM MODEL PR1390C121.
