1-4. How to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw
on most AC outlet boxes is also at earth ground.
If the retaining screw is to be used as your earth ground, verify that it is at ground
by measuring the resistance between it and a cold-water pipe with an ohmmeter.
The reading should be zero ohms
c) 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.
The reading should be zero ohms.
If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble- light (not
a neon lamp) between the hot side of the receptacle and the retaining screw. Try
both slots, if necessary, to locate the hot side on the line; the lamp should light at
normal brilliance if the screw is at ground potential (see Figure B).
• Correct hand placement while carrying the TV is very important for safety
and to avoid damages.
d) Components identified by shading and ! mark on the schematic diagrams,
exploded views, and in the parts list are critical for safe operation. Replace
these components with Sony parts whose part numbers appear as shown in
this manual or in supplements published by Sony. Circuit adjustments that
this manual or in supplements published by Sony. Circuit adjustments that
are critical for safe operation are identified in this manual. Follow these
procedures whenever critical components are replaced or improper
operation is suspected.
1-6. Lead Free Information
The circuit boards used in these models have been processed using Lead Free
Solder. The boards are identified by the LF logo located close to the board
designation.

a) These servicing instructions are for use by qualified service personnel only.
To reduce the risk of electric shock, do not perform any servicing other than
that contained in the operating instructions unless you are qualified to do so.
b) 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 servicing of these boards requires special precautions. It is strongly
recommended to use Lead Free Solder material in order to guarantee optimal
quality of new solder joints. Lead Free Solder is available under the following
part numbers:-
FFC can reverse insertion to connector of B board.
If reverse insertion FFC, all pins short-circuit, and board is broken.

1. Remove screw for Rear Cover and “COVER AC”.
( Refer Section 6 for screw information).
3. Release AC cable connector.
2. Open Rear Cover with “COVER AC” and AC cable are attached.
Make sure to hold cable not to give any tension to connector
and scratch damage for cable.
4. Release hook of “COVER AC” and remove it.
Note:
Note:
Take care not to cut your hand when release hook, especially metal Rear Cover.
Confirm if the hook broken before reuse COVER AC.
In case hook broken is occurred, replace with new one.
