SAFETY PRECAUTIONS

WARNING: The chassis of this receiver has a floating ground with the potential of one half the AC line voltage in respect to earth ground. Service should not be attempted by anyone not familiar with the precautions necessary when working 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 service is performed on the receiver.

2. Comply with all caution and safety-related notes provided inside the cabinet, on the chassis, and on the back.

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

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

4. Before replacing the back cover of the set, thoroughly inspect the inside of the cabinet to see that no stray parts or tools have been left inside.

Before returning any television to the customer, the service technician must perform the following safety checks 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 a jumper across the two blades. Connect one lead of an ohmmeter to the jumpered AC plug, and touch the other lead to each exposed antenna terminal (UHF and VHF antenna terminals). The resistance must measure between 1M ohm and

5.2M ohm. Any resistance value below or above this range

indicates an abnormality which requires corrective action.

PRODUCT SAFETY NOTICE

When replacing components in a receiver, always keep in mind the necessary product safety precautions. Pay special attention to the replacement of components marked with a star (★) in the parts list and in the schematic diagrams. To ensure safe product operation, it is necessary to replace those components with the exact same PARTS.

LEAKAGE CURRENT CHECK

Plug the AC line cord directly into a 120 VAC outlet. (Do not use an isolation transformer for this check.) Use an AC voltmeter, that has 5000 ohms per volt or more sensitivity. Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15 µF 150 VAC capacitor, between a known good earth ground (water pipe, conduit, etc.) and all exposed metal parts of the cabinet (antennas, handle bracket, metal cabinet, screw heads, metal overlays, control shafts, etc.). Measure the AC voltage across the 1500 ohm resistor. The AC voltage should not exceed 750 mV. A reading exceeding 750 mV indicates that a dangerous potential exists. The fault must be located and corrected. Repeat the above test with the receiver power plug reversed.

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

SAFETY INSTRUCTIONS

READING SHOULD NOT EXCEED 750 mV.

The CPU (IC801) is programmed so the set will go to the standby mode when there is a circuit failure as described below. (Refer to”Power Supply Lines” page 38.)

1. Power Failure 1: Detected voltage failure for analog circuit. (Connected to IC801 pin 52.)

(Normal: High, Failure: Low)

2. Power Failure 2: Detected voltage failure for Audio AMP IC. (Connected to IC801 pin 53.)

(Normal: Low; Failure: High)

3. Power Failure 3: Detected voltage failure for digital circuit. (Connected to IC801 pin 54.)

(Normal: High, Failure: Low)

4. Temperature Failure: Detected temperature failure for Main Power Unit. (Connected to IC801 pin 57.)

(Normal: Low, Failure: High)

LED Flashing

When IC801 detects the Power Failure the LED will flash to indicate a power failure has occurred. The number of flashes will be determined by the type of failure detected as shown below.

POWER FAILURE CIRCUIT

Note: If power failure is detected 3 times in 15 minutes, the set will enter the standby mode and cannot be

switched On. To reset the operating programs of the CPU it is necessary to disconnect the AC cord

for a short time.

History of Power Failure

When finishing the repair or stopping the Power Failure, the history of past failures can be checked.

To see the history

1. Enter the service mode. See “Service Adjustments” page 3.

2. Select Item No. 355 POWER ERROR from the Service Adjustment Data Table.

History of Power Failures (Item No. 355)

Note: If simultaneous failures have been detected, the sum of each data is displayed. For example:

Power failures 1 & 2 01h + 10h = 11h(17)

Attention:

After finishing service, reset the data of Item No. 355 with the < or >keys to “00h(0).”

Times of Flashes Failure Name

1 Power Failure 1 2 Power Failure 3 3 Power Failure 2 4 Temperature Failure

Failure Name Data

No Failure 00h(0) Power Failure 1 01h(1) Power Failure 3 04h(4) Power Failure 2 10h(16)

Temperature Failure 20h(32)
