SECTION 1
PRECAUTION
1.1 SAFETY PRECAUTIONS
(1) The design of this product contains special hardware and 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 product 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 product have special safety-related characteristics. These characteristics are often
not evident from visual inspection nor can the protection afforded by them necessary 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 the 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) The leads in the products are routed and dressed with ties, clamps, tubing’s, barriers and the like to be separated from live parts,
high temperature parts, moving parts and / or sharp edges for the prevention of electric shock and fire hazard. When service is
required, the original lead routing and dress should be observed, and it should be confirmed that they have been returned to
normal, after re-assembling.
WARNING
(1) The equipment has been designed and manufactured to meet international safety standards.
(2) It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
(3) Repairs must be made in accordance with the relevant safety standards.
(4) It is essential that safety critical components are replaced by approved parts.
(5) If mains voltage selector is provided, check setting for local voltage.

SPECIFIC SERVICE INSTRUCTIONS
2.1 FEATURES
• New chassis design enable use of an interactive on screen
control.
• The TELETEXT SYSTEM has a built-in FASTEXT (UK
system) and WST (world standard system) system.
• Because this TV unit corresponds to multiplex broadcast,
users can enjoy music programs and sporting events with live
realism. In addition, BILINGUAL programs can be heard in
their original language.
• Users can make VCR dubbing of picture and sound by
controlling the AV selector to select an optional source at the
EXT-2 output.

COATING OF SILICON GREASE FOR ELECTRICAL INSULATION ON THE CRT ANODE CAP SECTION.
Subsequent to replacement of the CRT and HV transformer or repair of the anode cap, etc. by dismounting them, be sure to coat
silicon grease for electrical insulation as shown in Fig.7. Wipe around the anode button with clean and dry cloth. (Fig.7) Coat silicon
grease on the section around the anode button. At this time, take care so that any silicon greases dose not sticks to the anode
button. (Fig.8)
