SELF-DIAGNOSTIC FUNCTIONSELF-DIAGNOSTIC FUNCTIONSELF-DIAGNOSTIC FUNCTIONSELF-DIAGNOSTIC FUNCTIONSELF-DIAGNOSTIC FUNCTION

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

Diagnostic TDiagnostic TDiagnostic TDiagnostic TDiagnostic Test Indicatorsest Indicatorsest Indicatorsest Indicatorsest IndicatorsWhen an error occurs, the STANDBY/TIMER LED will flash a set number of times to indicate the possible cause of the problem. Ifthere 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”.

After correcting the original service problem, perform thefollowing safety checks before releasing the set to thecustomer:

1. Check the area of your repair for unsoldered or poorlysoldered connections. Check the entire board surfacefor solder splashes and bridges.

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

3. Check that all control knobs, shields, covers, groundstraps, and mounting hardware have been replaced.Be absolutely certain that you have replaced all theinsulators.

4. Look for unauthorized replacement parts, particularlytransistors, that were installed during a previousrepair. Point them out to the customer andrecommend their replacement.

5. Look for parts which, though functioning, showobvious signs of deterioration. Point them out to thecustomer and recommend their replacement.

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

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

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

Leakage TLeakage TLeakage TLeakage TLeakage Testestestestest

The AC leakage from any exposed metal part to earthground and from all exposed metal parts to any exposedmetal part having a return to chassis, must not exceed0.5 mA (500 microampere). Leakage current can bemeasured by any one of three methods.

1. A commercial leakage tester, such as the Simpson229 or RCA WT-540A. Follow the manufacturers'instructions to use these instructions.

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

3. Measuring the voltage drop across a resistor bymeans of a VOM or battery-operated AC voltmeter.The “limit” indication is 0.75 V, so analog meters musthave an accurate low voltage scale. The Simpson’s250 and Sanwa SH-63Trd are examples of passiveVOMs that are suitable. Nearly all battery-operateddigital multimeters that have a 2 VAC range aresuitable (see Figure A).

How to Find a Good Earth GroundHow to Find a Good Earth GroundHow to Find a Good Earth GroundHow to Find a Good Earth GroundHow to Find a Good Earth Ground

A cold-water pipe is guaranteed earth ground; the cover-plate retaining screw on most AC outlet boxes is also atearth ground. If the retaining screw is to be used as yourearth ground, verify that it is at ground by measuring theresistance between it and a cold-water pipe with anohmmeter. The reading should be zero ohms. If a cold-water pipe is not accessible, connect a 60- to 100-watttrouble light (not a neon lamp) between the hot side of thereceptacle and the retaining screw. Try both slots, ifnecessary, to locate the hot side on the line; the lampshould light at normal brilliance if the screw is at groundpotential (see Figure B).

REMOVAL PROCEDURES

HOW TO HANDLE AN ANODE CAP

WARNING: High voltage remains in the CRT even after the power is disconnected. To avoid electrical shock, discharge the CRT beforeattempting to remove the anode cap. Short between anode and coated earth ground strap of CRT.

NOTE: After removing the anode, short circuit the anode of the picture tube and the anode cap to either the metal chassis, CRT shield,or carbon painted on the CRT.

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

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

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

2 Use your thumb to pull the rubbercap firmly in the direction indicatedby arrow b .

3 When one side of the rubber capseparates from the anode button,the anode cap can be removed byturning the rubber cap and pullingit in the direction of arrow c .

1 Turn up one side of the rubber cap inthe direction indicated by arrow a .

2. Input a dot signal and set PICTURE and BRIGHTNESSto minimum: IABL = 95 + 100/-95µA.

3. Confirm the voltage of A Board TP-600 is117.0 ± 0.3 VDC.

4. Connect the digital voltmeter and the DC power supplyvia diode 1SS119 to C574 (+) and ground(See Figure 1 on the following page).

5. Increase the DC power voltage gradually until the pictureblanks out.

6. Read the digital voltmeter indication.

7. Turn DC power source off immediately:(standard: less than or equal to 127.3 VDC).

8. Input a white signal and set PICTURE and BRIGHTNESSto maximum: (standard: less than or equal to 127.3 VDC).
