SAFETY NOTES

1-1. Warnings and Caution.
1) CAUTION :These servicing instructions are for use by qualified service
personnel only.
2) To reduce the risk of electric shock, do not perform any servicing other than
that stated in the operating instructions unless you are qualified to do so.
3) WARNING!!: An isolation transformer should be used during any service to
avoid possible shock hazard, because of live chassis. The chassis of this
receiver is directly connected to the ac power line. The replaceable fuse should
be in the neutral of the mains supply. When replacing the fuse, the mains must
be disconnected to de-energize the phase conductors. (*Except AC ADAPTOR,
because it does not carry out replacing an internal fuse.)
4) CARRYING THE TV: be sure to follow these guidelines to protect your
property and avoid causing serious injury:
- Carry the TV with an adequate number of people; larger size TVs require
two or more people.
- Correct hand placement while carrying the TV is very important for
safety and to avoid damages.
5) SAFETY-RELATED COMPONENT WARNING!!: Components identified by
shading and mark on the exploded views, and in the parts list are critical
for safe operations. Replace these components with Sony parts whose part
numbers appear as shown in this manual or in supplements published by Sony.
Circuit adjustments that are critical for safe operations are identified in this
manual. Follow these procedures whenever critical components are replaced,
or improper operation is suspected.
6) IMPORTANT REMINDER FOR TV MAIN BOARD REPLACEMENT:
It is mandatory for service centers to confirm the TV's system information after
each repair is carried out with Main board replacement. Whenever a TV Main board
is replaced, the correct TV Model and Serial number must be reinserted into
memory. This is a MANDATORY procedure that each service center must apply.
