SAFETY PRECAUTIONS

WARNING: The chassis of this receiver has a floatingground with the potential of one half the AC line voltage inrespect to earth ground. Service should not be attempted byanyone not familiar with the precautions necessary whenworking on this type of equipment. The following precautions must be observed:1. An isolation transformer must be connected in the power

line between the receiver and the AC line before any ser-vice is performed on the receiver.

2. Comply with all caution and safety-related notes provid-ed on the side of the cabinet, inside the cabinet, on thechassis, and the picture tube.

3. When replacing a chassis in the cabinet, always be certainthat all the protective devices are installed properly, suchas control knobs, adjustment covers, shields and barriers.

DO NOT OPERATE THIS TELEVISION RECEIVER WITHOUT THE PROTECTIVE SHIELD IN POSITION ANDPROPERLY SECURED.

4. Before replacing the back cover of the set, thoroughlyinspect the inside of the cabinet to see that no stray partsor tools have been left inside.Before returning any television to the customer, the service technician must perform the following safetychecks to be sure that the unit is completely safe to operate without danger of electrical shock.

ANTENNA COLD CHECK

Remove AC plug from the 120 VAC outlet and place ajumper across the two blades. Connect one lead of an ohm-meter to the jumpered AC plug, and touch the other lead toeach exposed antenna terminal (UHF and VHF antenna ter-minals). The resistance must measure between 1M ohm and5.2M ohm. Any resistance value below or above this rangeindicates an abnormality which requires corrective action.

LEAKAGE CURRENT CHECK

Plug the AC line cord directly into a 120 VAC outlet. (Do notuse an isolation transformer for this check.) Use an AC volt-meter, that has 5000 ohms per volt or more sensitivity.Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15 µF150 VAC capacitor, between a known good earth ground(water pipe, conduit, etc.) and all exposed metal parts of thecabinet (antennas, handle bracket, metal cabinet, screwheads, metal overlays, control shafts, etc.). Measure the ACvoltage across the 1500 ohm resistor. The AC voltageshould not exceed 750 mV. A reading exceeding 750 mVindicates that a dangerous potential exists. The fault mustbe located and corrected. Repeat the above test with thereceiver power plug reversed.

NEVER RETURN A RECEIVER TO THE CUSTOMER WITHOUT TAKING THE NECESSARY CORRECTIVE ACTION.

X-RADIATION PRECAUTION

The primary source of X-RADIATION in solid-state receivers isthe picture tube. The picture tube is specially constructed tolimit X-Ray emission. For continued X-RADIATION protection,the replacement tube must be the same type as the original(including the suffix letter in the part numbers). Excessive highvoltage may produce potentially hazardous X-RADIATION. Toavoid such hazards, the high voltage must be maintained withinspecific limits. Refer to the X-RADIATION WARNING NOTE onthe CHASSIS SCHEMATIC in this service manual for specifichigh voltage limits. If the high voltage exceeds specified limits,check the components specified on the chassis schematicdiagram and take the necessary corrective action. Carefullyfollow the instructions for the +B Voltage Check and the HighVoltage Check to maintain the high voltage within the specifiedlimits.

HIGH VOLTAGE HOLD-DOWN TEST

To prevent X-RADIATION from the picture tube due toexcessive high voltage, a HOLD-DOWN circuit is provided inthe high voltage circuit. Every time the receiver is serviced,the high voltage HOLD-DOWN circuit must be tested forproper operation. Refer to the HIGH VOLTAGE HOLD-DOWN TEST in service adjustments.

PRODUCT SAFETY NOTICE

When replacing components in a receiver, always keep inmind the necessary product safety precautions. Pay specialattention to the replacement of components marked with astar ( ) in the parts list and in the schematic diagrams. Toensure safe product operation, it is necessary to replacethose components with the exact same PARTS.

Note: Do not set to excessive brightness level, otherwisethe contrast level will be suppressed.

HIGH VOLTAGE HOLD-DOWN TESTEvery time the receiver is serviced, the HIGH VOLTAGE HOLD-DOWN circuit must be tested for proper operation by following these steps:

1. Connect receiver to 120V AC line. Tune receiver to activechannel. Reset the picture controls to the Auto levels.

2. Check that the voltage measured between TP7 and TE7(ground side) is within 16.5 VDC to 21 VDC. If the voltageis out of this range, the Hold-Down Circuit must be checked.

3. Connect a DC Voltage supply to TP7 and TE7 through a100 ohm 1/4W resistor. Adjust the DC voltage to 23 VDC.The receiver should shutdown, losing raster and sound.Then the receiver should turn off automatically. Thisreaction indicates that the Hold-Down circuit is function-ing properly. If the receiver does not shutdown, amalfunction is indicated and its cause must be found andcorrected.

4. To obtain picture again, remove the DC Supply and waita few minutes. Now turn on the receiver.

HIGH VOLTAGE CHECK

Note: +B (+130V) Voltage Check and Grayscale Adjustmentmust be completed before attempting High VoltageCheck.

1. Connect high voltage voltmeter – lead to ground, andconnect + lead to anode of picture tube.

2. Tune receiver to an active channel and confirm TV isoperating properly.

3. Eliminate the beam current by adjusting the contrast andbrightness controls to minimum.

4. Confirm high voltage is within 27.4 KV and 31.9 KV. Ifreading is not within range, check horizontal circuit.

No high voltage adjustment is provided on this chassis.

SERVICE HINTS

POWER FAILURE DETECTOR

This unit is equipped with a Power Failure Detector function included in the CPU which checks for an abnormal condition inthe chassis power supplies, including the power supply derived from the Horizontal Output Transformer.

If, while the power is on, a failure is caused by any of the following that results in a low voltage supply, the CPU will turn theunit off in 1.5 seconds to prevent unnecessary damage:

• Failure within the power supply circuits.

• A short circuit in the load side from the supply.

• Stoppage of the Horizontal Output Oscillator caused by the X-Radiation protection Hold-Down Circuit.

If, while the power is off, the power is switched on and any of these failures remains uncorrected, the CPU will shut off thepower within three seconds.

Check the following if the unit is turned off by the power failure detector.

1. Disconnect the AC power cord (120V AC line) for at least 10 seconds.2. Connect a DC Voltmeter to the following TEST POINTS.

3. Press the Power key and check for the proper voltage supplies.4. If any of these voltages is low, the power failure detector should turn the unit off within three seconds.5. Check all circuits listed above.

Note: This unit is equipped with a Power Surge Protection feature included in the CPU. If power failure occurs three timeswithin 15 minutes, the CPU will automatically stop functioning to help prevent secondary damage. (TV will not turn onby pressing the power key.) To reset the operating programs within the CPU, disconnect the AC power cord for at least10 seconds.
