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 contact 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 right.
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 WT­540A. Follow the manufacturers’ instructions to use these instruments.
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 250 and Sanwa SH-63Trd are examples of a passive VOMs that are suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)

REMOVAL OF ANODE-CAP
NOTE: Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon painted on the CRT, after
removing the anode.
REMOVING PROCEDURES
b
a
1Turn up one side of the rubber cap in the
direction indicated by the arrow a.
2Using a thumb pull up the rubber cap
firmly in the direction indicated by the arrow b.
HOW TO HANDLE AN ANODE-CAP
1Don’t scratch the surface of anode-caps with sharp shaped
material!
2Don’t press the rubber hardly not to damage inside of anode-
caps! A material fitting called as shatter-hook terminal is built in the rubber.
3Don’t turn the foot of rubber over hardly!
The shatter-hook terminal will stick out or damage the rubber.
c
Anode Button
3When one side of the rubber cap is
separated from the anode button, the anode-cap can be removed by turning up the rubber cap and pulling up it in the direction of the arrow c.

Landing Rough Adjustment
1. Enter the full white signal. (or the full black dots signal)
2. Set the contrast to “CONT”=MAX.
3. Make the screen monogreen. Note: Off the outputs from R ch and B ch of SG.
4. Reverse the DY, and adjust coarsely the purity magnet so that a green raster positions in the center of screen.
5. Adjust the "H.CENTER" with the H CENTER Volume .(RV502 on the D board)
6. Moving the DY forward, adjust so that an entire screen becomes monogreen.
7. Adjust the tilt of DY, and fix lightly with a clamp.
Note: “TILT” shall be set at 0
Landing Fine Adjustment
1. Put the set inside the Helmholtz coil.
5. Attach the wobbling coil to the designated part of the CRT neck.
6. Attach the sensor of the landing adjustment unit on the CRT surface.

7. Adjust the DY position and purity, and the DY tilt.
8. Fasten DY with screw.
2. Set the TLH to the Zero position.
3. Receive the single green signal.
4. Demagnetize the CRT surface with the hand degausser , and perform
auto degaussing.
Note:Torque 22 ±2kgcm (2.2 ± 0.2 Nm)
Perform auto degaussing.

9. Adjust each top and bottom pins by two wedges and then not swing DY
13. If using the magnet, be sure to demagnetize with the degausser and neck right and left. (When fixing DY with wedges, insert wedges completely so that the DY does not shake.)

"a" and "b" must be equal.
10. Adjust the top and bottom pins with the TB.PIN VR complettely. And ajust the V.Size simulation.
11. Adjust the V.key (=H.Trapxoid) with the H-Trp VR so that [a] become equol to the [b]

14. Remove the sensor and wobbling coil.
15. Fix the purity magnet paisted on the DY with the white pen.Fix it with the RTV.
Convergence Rough Adjustment

12. If the corner is not within the standards, adjust disc magnet to satisfy L/ D adjustment standards.
Note: (1) When necessary to paste magnets more than 2 pieces, be careful that the
convergence and the distortion would be alterable.
(2) Paste within 80 to 120 mm from the DY on the diagonal line of the
magnet.
3. Adjust H. STAT and V. STAT with 4 pole magnet.
4. Recieve the white crosshatch signal.(White line on black)
5. Adjust HMC and VMC with the 6 pole magnet.

"YBH_T_HI", "TBH_T_LO" "YBH_B_HI", "YBH_B_LO" "VSTAT_T_HI", "VSTAT_T_LO" "VSTAT_B_HI""VSTAT_B_HI"
9. Adjust the H Static and V Static with the register "HSTAT_HI" and "VSTAT_HI". (These registers should be within the limit between -40 and +40.)
10. Insert to TLH correction board and correct H. TILT.
11. Adjust XCV with the XCV volume.
12 Adjust YCH with the YCH volume. 13 Adjust V. TILT with the TLV-VR.
