SELF-DIAGNOSTIC FUNCTION

The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to flash. The number of times the LED flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER LED flash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the Remote Commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.

Diagnostic Test Indicators

When an error occurs, the STANDBY/TIMER LED will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the first of the problem areas. Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.

Handling of Self-Diagnostic Screen Display

Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during repairs. When you have completed the repairs, clear the result display to “0”. Unless the result display is cleared to “0”, the self-diagnostic function will not be able to detect subsequent faults after completion of the repairs.

Clearing the Result Display

To clear the result display to “0”, press buttons on the Remote Commander sequentially when the diagnostic screen is displayed, as shown below:

+B overcurrent (OCP) Occurs when an overcurrent on the +B (135V) line is detected by pin 18 of IC355 (A Board).

If the voltage of pin 18 of IC355 (A Board) is less than 1V when V.SYNC is more than seven verticals in a period, the unit will automatically turn off.

+B overvoltage (OVP) Occurs when the feedback circuit from +B opens IC643 or T603 (G Board)/IC6003 or PH6001

(GA Board) or any other associated feedback components.

V-STOP Occurs when an absence of the vertical deflection pulse is detected by pin 15 of IC355 (A

Board). Power supply will shut down when waveform interval exceeds 2 seconds.

IK (AKB) If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will

be detected by IC355 (A Board). TV will stay on, but there will be no picture.

*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer:

1. Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface for solder splashes and bridges.

2. Check the interboard wiring to ensure that no wires are “pinched” or touching high-wattage resistors.

3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators.

4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement.

5. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement.

6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer.

7. Check the B+ and HV to see if they are specified values. Make sure your instruments are accurate; be suspicious of your HV meter if sets always have low HV.

8. Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

Leakage Test

The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instructions.

2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low voltage scale. The Simpson’s 250 and Sanwa SH-63TRD are examples of passive VOMs that are suitable. Nearly all batteryoperated digital multimeters that have a 2 VAC range are suitable (see Figure A).

How to Find a Good Earth Ground

A cold-water pipe is a guaranteed earth ground; the coverplate retaining screw on most AC outlet boxes is also at earth ground. If the retaining screw is to be used as your earth ground, verify that it is at ground by measuring the resistance between it and a cold-water pipe with an ohmmeter. The reading should be zero ohms. If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble- light (not a neon lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should light at normal brilliance if the screw is at ground potential (see Figure B).

7. Place the set with the CRT face down on a cushion and remove the degaussing coil holders.

8. Remove the degaussing coils.

9. Remove the CRT grounding strap and spring tension devices.

10. Unscrew the four CRT fixing screws [located on each CRT corner] and remove the CRT [Take care not to handle the CRT by the neck].

REMOVAL PROCEDURES

Anode Button

Turn up one side of the rubber cap in the direction indicated by arrow

Use your thumb to pull the rubber

cap firmly in the direction indicated by arrow

When one side of the rubber cap separates from the anode button, the anode cap can be removed by turning the rubber cap and pulling it in the direction of arrow

HOW TO HANDLE AN ANODE CAP

Do not use sharp objects which may cause damage to the surface of the anode cap.

To avoid damaging the anode cap, do not squeeze the rubber covering too hard. A material fitting called a shatter-hook terminal is built into the rubber.

Do not force turn the foot of the rubber cover. This may cause the shatter-hook terminal to protrude and damage the rubber.

SAFETY RELATED ADJUSTMENTS

3-1. R530, R531 CONFIRMATION METHOD

(HOLD-DOWN CONFIRMATION) AND READJUSTMENTS

Always perform the following adjustments when replacing the following components marked with a diagram:

Part Replaced ( ) Adjustment ( )

R387, R550, R529, R530, R531, R532, R533, D519, D520, D521, IC501, C531, C532, T503, IC351, IC355, D302, Q301, R356, R359,

IC643, R661 .................. G Board

IC6003,R6008 ............. GA Board

mark on the schematic

HV HOLD-DOWN R530, R531

Preparation before Confirmation

1. Using a V ariac, apply AC input voltage: 130+2.0/-0.0 VAC.

2. Turn the POWER switch ON.

3. Input a white signal and set the PICTURE and BRIGHT controls to maximum.

4. Confirm that the voltage of more than 23.0 VDC appears between TP85 and ground on the A Board.

Hold-Down Readjustment

If the setting indicated in Step 2 of Hold-Down Operation Confirmation cannot be met, readjustment should be performed by altering the resistance value of R530, R531 component marked with

digital multimeter

ammeter 3mA DC range

Hold-Down Operation Confirmation

1. Connect the current meter between Pin 11 of the FBT (T503) and the PWB land where Pin 11 would normally attach (See Figure 1 above).

2. Input a dot signal and set PICTURE and BRIGHTNESS to minimum: IABL = 2175 + 100/ -325 µA.

3. Confirm the voltage of A Board TP91 is 135 ± 1.5 VDC.

4. Connect the digital voltmeter and the DC power supply to TP85 and ground. (See Figure 1 above).

5. Increase the DC power voltage gradually until the picture blanks out.

6. Turn DC power source off immediately.

7. Read the digital voltmeter indication (standard = 27.24 + 0.0/ - 0.1 VDC).

8. Input a white signal and set PICTURE and BRIGHTNESS to maximum: IABL = 2175 + 100/ -325 µA.

9. Repeat steps 4 to 7.

3-2. B+ VOLTAGE CONFIRMATION AND

ADJUSTMENT

Note: The following adjustments should always be performed when replacing the following components, which are marked with on the schematic diagram on the G Board or GA Board.

G BOARD: IC643, R661 GA BOARD: IC6003, R6008

1. Using a V ariac, apply AC input voltage: 130 + 2.0/-0.0 VAC

2. Input a monoscope signal.

3. Set the PICTURE control and the BRIGHT control to initial reset value.

4. Confirm the voltage of G Board CN641 or GA Board CN6007 between pin

5. If step 4 is not satisfied, replace the R661 on G Board or R1008 on GA Board and repeat the above steps.
