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 milliampmeter. 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 battery-operated 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 cover-plate 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).

SELF-DIAGNOSTIC FUNCTION
Self Diagnosis
Supported model
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to ash. The number of times the LED ashes translates to a probable source of the problem. A denition of the STANDBY/TIMER LED ash 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 ash 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 rst 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".

Self-Diagnostic Screen Display For errors with symptoms such as "power sometimes shuts off" or "screen sometimes goes out" that cannot be confirmed, it is possible to bring up past occurrences of failure on the screen for confirmation. To Bring Up Screen Test In standby mode, press buttons on the Remote Commander sequentially, in rapid succession, as shown below: Display Channel 5 Sound Volume Power ON Note that this differs from entering the Service Mode (Sound Volume + ). Self-Diagnostic Screen Display SELF DIAGNOSTIC 2: 000 3: N/A 4: 000 5: 001 101: N/A
Numeral "0" means that no fault was detected. Numeral "1" means a fault was detected one time only.
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: Channel 8 ENTER

Anode Button
Turn up one side of the rubber cap in the direction indicated by arrow a . Use your thumb to pull the rubber cap firmly in the direction indicated by arrow b . 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 c .
HOW TO HANDLE AN ANODE CAP
1. Do not use sharp objects which may cause damage to the surface of the anode cap. 2. 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. 3. Do not force turn the foot of the rubber cover. This may cause the shatter-hook terminal to protrude and damage the rubber.
