SERVICE ADJUSTMENTS
Required Tools For Servicing:
Isolation Transformer
Multimeter
Oscilloscope
High Voltage (100:1) Oscilloscope Probe
Sencore VG91 Universal Video Generator
Service Adjustment Notes:
Unless Otherwise Specified:
1. All service adjustments are "hot" voltagewise. For maximum safety, ensure
the use of properly insulated tools.
2. Refer to the F8 Main Chassis Printed Circuit Board for location of test
points and adjustable components.
3. Grid Locations (Ex.: D-2) next to the reference numbers for components
refer to the Main Chassis Printed Circuit Board.
Caution: The F8 chassis incorporates a "hot" ground system. Always use a
separate isolation transformer when applying power to the exposed chassis.
Focus Adjustment
1. Tune the set to a local or cable station.
2. Adjust the Focus Control (located on the upper part of the flyback
transformer) for best picture details at high light conditions.
Degaussing the Television
1. Position the television so that the screen faces the direction it will be
facing when in use.
2. Ensure the set is turned off.
3. Move a degaussing coil in a circular motion slowly around the sides and
front of the set.
4. Withdraw the degaussing coil at least six feet from the television before
disconnecting it from its power source.
Service Modes:
Introduction
1. There are three service modes used in the F8 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 waveforms
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 servicer 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 memorized 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.
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.
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)
Service Default Mode (SDM)
1. The Service Default Mode (SDM), sets the option codes and bytes of the
set, and displays the error codes (the Power LED begins blinking procedure
for error code display, if errors are detected). SDM also overrides software
protections.
The Service Default Mode (SDM) must be used when taking voltages and
waveforms.
2. To enter the Service Default Mode, press the following key sequence on
the remote control transmitter:
0-6-2-5-9-6-Menu
Do not allow the display to time out between entries while keying the
sequence.
SDM can also be entered by pressing the Channel Down and Volume Down keys on
the local keyboard simultaneously while in SAM mode.
When Service Default Mode is entered, the text "SDM" will be displayed in
the upper right corner of the screen.
3. When Service Default Mode is entered, the Power LED will begin blinking
to display any detected error codes, the set automatically tunes to Channel
3 (61.25 MHz), and service unfriendly modes are disabled. All customer
controls are set to predetermined values.
4. When the unit is operating in Service Default Mode, all normal on-screen
displays are suppressed and replaced by a special service display. A sample
SDM display is shown below.
5. To select an option code or option byte in SDM, use the Menu Up or Menu
Down keys on the remote control.
6. To change the value of an option code, use the Menu Left or Menu Right
keys.
7. To change the value of an option byte, enter the new value using the
numeric keys on the remote control.
8. Press the Status button on the remote control to toggle the OSD (except
"SDM") ON and OFF to prevent the OSD from interfering with measurements and
oscilloscope waveforms.
9. Press the Menu button on the remote control while in SDM to switch the
software to a Virtual Customer Mode; the text "SDM" will still be displayed
in the upper right corner of the screen. In this mode, all customer menu
adjustments to the set can be made. From the Virtual Customer Mode, press
the Menu button to return to the SDM display.
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.
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:
L90US11 1.0)
- 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: 11 = English/Spanish/French)
- X is the main version number (Ex: 1)
- Y is the sub version number (Ex: 0)
- 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
· 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.
Example 1:
Suppose the display shows: 8 - 11 - 2- 0 - 0
With 2 displayed at the right of the error buffer, high beam current
protection is active.
Example 2:
Suppose the display shows: 11 - 4 - 5- 3 - 0
With 3 displayed at the right of the error buffer, vertical protection is
active.
The following error codes have been defined:
Error Code Table:
0 = No error
1 = X-Ray / overvoltage protection active
2 = High beam current (BCI) protection active
3 = Vertical protection active
4 = I²C error while communicating with the sound processor (IC 7833)
5 = Signal processor (IC 7250) start-up error
6 = I²C error while communicating with the signal processor IC (IC 7250)
7 = General I²C error *
8 = Internal RAM error micro controller
9 = EEPROM Configuration error (Checksum error)
10 = I²C error, EEPROM error
11 = I²C error, PLL tuner
Note: I²C = (SCL/SDA)
* General I²C error means: no I²C device is responding to the particular I²C
bus. Possible causes: SCL short circuit to GND, SDA short circuit to GND,
SCL short circuit to SDA, SDA open circuit (at IC 7600), SCL open circuit
(at IC 7600)
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. If the on screen display is not working, do the following:
a. Remove AC power
b. Use a jumper to connect pin M24 to pin M25 at IC 7601 (D-3)
c. Apply AC power; read the error codes (see LED Sequence List below)
d. If there is no LED indication, take the following steps as needed:
Power on
Press 0-6-2-5-9-6-Menu on the remote control
Note: Some indications take 30 seconds or longer to appear on the LED.
3. LED Sequence List:
a. Wait for long LED on (1.5 seconds)
b. Count the following on flashes (individual errors are separated by 1.5
seconds LED off)
Example:
4. Displayed error codes are saved by removing the AC power. Displayed error
codes are erased by pressing the power button on the remote control or local
keyboard.

in the upper right corner of the screen. In this mode, all customer menu
adjustments to the set can be made. From the Virtual Customer Mode, press
the Menu button to return to the SAM Menu.
9. Press the Status button on the remote control to toggle the OSD (except
"SAM") ON and OFF.
10. To exit the Service Alignment Mode, turn the set off with the Power
button on the remote control. To turn off the set without exiting SAM (or
erasing any stored error codes), unplug the AC cord. When the set is powered
on again, the Service Alignment Mode will still be active.
Note: When SAM is exited or a power interrupt occurs, the volatile SAM items
AKB, VSD, AFW, and SBL will be reset to their original values.
