Only qualified service technicians who are familiar with safety checks
and guidelines should perform service work. Before replacing parts,
disconnect power source to protect electrostatically sensitive parts. Do
not attempt to modify any circuit unless so recommended by the
manufacturer. When servicing the receiver, use an isolation transformer
between the line cord and power receptacle.

Use EXTREME CAUTION when servicing the high voltage circuits. To
discharge static high voltage, connect a 10K ohms resistor in series with a
test lead between the receiver ground and CRT anode lead. DO NOT lift
the CRT by the neck. Always wear shatterproof goggles when handling
the CRT to protect eyes in case of implosion.

Be aware of the instructions and procedures covering X-ray radiation. In
solid-state receivers and monitors, the CRT is the only potential source of
X-rays. Keep an accurate high voltage meter available at all times. Check
meter calibration periodically. Whenever servicing a receiver, check the
high voltage at various brightness levels to be sure it is regulating
properly. Keep high voltage at rated value, NO HIGHER. Excessive high
voltage may cause X-ray radiation or failure of associated components.
DO NOT depend on protection circuits to keep voltage at rated value.
When troubleshooting a receiver with excessive high voltage, avoid close
contact with the CRT. DO NOT operate the receiver longer than
necessary. To locate the cause of excessive high voltage, use a variable
AC transformer to regulate voltage. In present receivers, many electrical
and mechanical components have safety related characteristics which are
not detectable by visual inspection. Such components are identified by a
##
# on both the schematic and the parts list. For SAFETY, use only
##
equivalent replacement parts when replacing these components.

Perform a final SAFETY CHECK before returning receiver to customer.
Check repaired area for poorly soldered connections, and check entire
circuit board for solder splashes. Check board wiring for pinched wires or
wires contacting any high wattage resistors. Check that all control knobs,
shields, covers, grounds, and mounting hardware have been replaced. Be
sure to replace all insulators and restore proper lead dress.

Unplug the AC cord, connect a jumper across the plug prongs, and turn
the power switch on (if applicable). Use an ohmmeter to measure the
resistance between the jumped AC plug and any exposed metal cabinet
parts such as antenna screw heads, control shafts, or handle brackets.
Exposed metal parts with a return path should measure between 1M
ohms and 5.2M ohms. Parts without a return path must measure infinity.

Plug the AC cord directly into an AC outlet. DO NOT use an isolation
transformer. Use a 1500 ohms, 10W resistor in parallel with a .15µF
capacitor to connect between any exposed metal parts on the receiver and
a good earth ground. (See figure below.) Use an AC voltmeter with at
least 5000 ohms per volt sensitivity to measure the voltage across the
resistor. Check all exposed metal parts and measure voltage at each point.
Voltage measurements should not exceed .75VAC, 500µA. Any value
exceeding this limit constitutes a potential shock hazard and must be
corrected. If the AC plug is not polarized, reverse the AC plug and repeat
exposed metal part voltage measurement at each point.

Apply 120VAC. Use the remote to set customer controls for normal operation. Momentarily short BC14901
base of Q14901 to ground. The receiver should lose raster and sound. If receiver does not lose raster and
sound, the shutdown circuit should be repaired. To resume normal operation, remove AC power for
approximately 30 seconds and then turn the receiver on.

To access the service menu, turn the receiver on, press the menu button on
the front panel, and hold it down while pressing the power button. While
holding down the menu button, release the power button and press the
volume + button. The screen will display a one line menu, on the left the
parameter P0, and on the right the value of that parameter V0. Release
buttons. Adjustments are made by selecting the proper parameter and
changing the value of that parameter. To change the parameter number use
channel up and down buttons. To adjust the current value of that parameter
use volume + and - buttons. To access and change any of the adjustments,
the proper parameter pass number must be entered. This information is
listed at the beginning of the alignment. When these parameters are
modified, the T-Chip and the corresponding EEPROM are updated. All
service adjustments are bus controlled, except focus and screen.
NOTE: In order to adjust the RF AGC, audio or video levels, tuner, PIP, or
stereo circuits, the Chipper Check hardware and software must be used.
This can be purchased from Thomson Electronics.

you to have clear details of the picture, press the VOL UP button to advance
the Value range to “80”, then press CH UP.
The incoming Video signal will be blanked out and a crosshatch pattern
with a small yellow centered cursor will be displayed. The volume and
channel buttons will move the cursor up, down, left, and right in single
steps. The four navigation move buttons on the remote will adjust the
selected color at the cursor point. The green color will be stationery, the red
and blue colors are to be adjusted to the green. To select between the Red,
or Blue adjustment press the INFO or DISPLAY button on the remote
control. When INFO button is pressed the cursor color change from yellow
to cyan indicating that the color to be adjusted is the blue instead of the red.
Pressing the power button on the remote will end and save changes to the
DigiCon EEPROM, and the screen will return to normal signal reception.
NOTE: Before making any changes in the service adjustments its recommended to keep a record of the on set values.
