SERVICE
SAFETY CHECKS — FIRE AND SHOCK HAZARD
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.

Receiverss with Isolated Gr
Ground
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.

TAGE LIMITS
X-RAY
RADIATION
OLT
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.
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.
Hot Leaka
ge Current Chec
Leakag
Checkk
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.
GENERAL GUIDELINES
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.

SHUTDOWN
Turn receiver on, adjust customer controls for normal operation. Temporarily apply an external bias of
14.0V to the emitter of QX3002. The receiver should lose raster. If the receiver does not lose raster the
shutdown circuit should be repaired. Remove AC power, wait 30 seconds and test for normal operation.

To access the service menu adjustments by using the remote transmitter
keypad, press and hold the menu button until the menu display disappears
from the screen. Key in 9, 8, 7, 6, and press the enter button.
Tune in a crosshatch pattern. Set brightness, picture, and color to minimum.
Call up service menu, select functions 27, 28, and 29, set data values to 0.
Adjust data values for functions 30, 31, and 32 of the two least predominate
colors to obtain a white pattern. Tune in an active black and white channel
and adjust functions 27, 28, and 29 for best white to black tracking at high

To access the service menu adjustments by using the receiver keypad, press
the menu button until the display disappears from the screen. Without
releasing the menu button simultaneously press the adjust right and channel
up buttons.
The receiver is now in service menu mode with function 03 H Pos 16
displayed. The first line on the service menu is a version number of the
software used in the receiver. On the bottom is a date the module went
through the factory. Use the select up and down buttons to select function.
Use the adjust buttons to make changes to selected function. The function
00 F Mode (Factory Mode) is always set to 0. Only the first seven items in
the service menu can be brought up. Use the select key to select the 00 F
Mode function and change the adjustment to 1, now all the menu items will
be accessible.
NOTE: Set value of function 00 F Mode (Factory Mode) to 0 before exiting
the service menu mode. If not set to 0 the receiver will not shut off with the
remote or power button on the receiver.
Tune in a crosshatch pattern. Call up service menu, select function 11, set
data value for slight overscan on both sides.
