SAFETY PRECAUTIONS
1.
The design of this product contains special hardware, many circuits and components specially for safety purposes. For continued protection,
no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to
those used in the original circuits. Service should be performed by qualified personnel only.
2.
Alterations of the design or circuitry of the products should not be made. Any design alterations or additions will void the manufacturer's
warranty and will further relieve the manufacturer of responsibility for personal injury or property damage resulting therefrom.
3.
Many electrical and mechanical parts in the products have special safety-related characteristics. These characteristics are often not evident
from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher
voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in the parts list of Service manual.
Electrical components having such features are identified by shading on the schematics and by ( !) on the parts list in Service
manual. The use of a substitute replacement which does not have the same safety characteristics as the recommended replacement part
shown in the parts list of Service manual may cause shock, fire, or other hazards.
4.
Don't short between the LIVE side ground and ISOLATED (NEUTRAL) side ground or EARTH side ground when repairing.
Some model's power circuit is partly different in the GND. The difference of the GND is shown by the LIVE : (") side GND, the
ISOLATED(NEUTRAL) : (#) side GND and EARTH : ($) side GND. Don't short between the LIVE side GND and ISOLATED(NEUTRAL)
side GND or EARTH side GND and never measure with a measuring apparatus (oscilloscope etc.) the LIVE side GND and
ISOLATED(NEUTRAL) side GND or EARTH side GND at the same time.
If above note will not be kept, a fuse or any parts will be broken.
5.
If any repair has been made to the chassis, it is recommended that the +B setting should be checked or adjusted (See +B ADJUSTMENT).
6.
The high voltage applied to the picture tube must conform with that specified in Service manual. Excessive high voltage can cause an
increase in X-Ray emission, arcing and possible component damage, therefore operation under excessive high voltage conditions should
be kept to a minimum, or should be prevented. If severe arcing occurs, remove the AC power immediately and determine the cause by
visual inspection (incorrect installation, cracked or melted high voltage harness, poor soldering, etc.). To maintain the proper minimum level
of soft X-Ray emission, components in the high voltage circuitry including the picture tube must be the exact replacements or alternatives
approved by the manufacturer of the complete product.
7.
Do not check high voltage by drawing an arc. Use a high voltage meter or a high voltage probe with a VTVM. Discharge the picture tube
before attempting meter connection, by connecting a clip lead to the ground frame and connecting the other end of the lead through a 10k
"
2W resistor to the anode button.
8.
When service is required, observe the original lead dress. Extra precaution should be given to assure correct lead dress in the high voltage
circuit area. Where a short circuit has occurred, those components that indicate evidence of overheating should be replaced. Always use
the manufacturer's replacement components.
