WARNING
-
The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug and power receptacle, when servicing this chassis. To prevent electric shock, do not remove cover. No user - serviceable parts inside. Refer servicing to qualified service personnel.
SHARP CORPORATION
IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service personnel only. SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE TUBE
When servicing the high voltage system, remove static charge from it by connecting a 10 kohm Resistor in series with an insulated wire (such as a test probe) between picture tube dag and 2nd anode lead. (AC line cord should be disconnected from AC outlet.)
1. 2. 3. 4. Picture tube in this receiver employs integral implosion protection. Replace with tube of the same type number for continued safety. Do not lift picture tube by the neck. Handle the picture tube only when wearing shatterproof goggles and after discharging the high voltage completely.
X-RAY
This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions or servicing may produce potentially hazardous radiation with prolonged exposure at close range, the following precautions should be observed:
1. 2. When repairing the circuit, be sure not to increase the high voltage to more than 25.3kV, (at beam 800uA) for the set. To keep the set in a normal operation, be sure to make it function on 22.0kV + 1.5kV (at beam 800@) in the case of the set. The set has been factory - Adjusted to the above-mentioned high voltage. . . . If there is a possibility that the high voltage fluctuates as a result of the repairs, never forget to check for such high voltage after the work. Do not substitute a picture tube with unauthorized types and/or brands which may cause excess X-ray radiation.
3.
BEFORE RETURNING THE RECEIVER
Before returning the receiver to the user, perform the following safety checks.
Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the receiver. 2. Inspect all protective devices such as non-metallic control knobs, insulating fishpapers, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacity networks, mechanical insulators etc. 1.

If the right and left green spots are both deviated outwards from their landing positions as shown in Fig. B, push the deflection yoke forwards until their positions are corrected. 8. If the beam landing is shifted to right or left as shown in Figs. Cand D, adjust the opening degree of the purity magnet so that the beam landing is correctly positioned. 9. Adjust the purity magnet so that the beam landing is correct at either of the central part, right and left parts of screen, then check that the green beams at four corners of screen are all correctly positioned. Finally, check that the beam landing at any pat of screen is satisfactory with the Rank "B" specifications. 10. If the green beam is positioned to mix with the other colour, pull the deflection yoke backward. l Outside of the specified landing: To front of the deflection yoke. l Inside of the specified landing: To back of the deflection yoke. 11. Set the raster rotation at "0" position (with the unit facing the east). 12. Tighten the screws of the deflection coil. Tightening torque: 11 kg + 2 kg. 6.
