(4) As shown in Fig. 6, use the crimping tool to crimp the
metal sleeve at the center position. Be sure to crimp fully
to the complete closure of the tool.

e@Safety Check after Servicing
Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have been returned
to original positions, Afterwards, performe the following tests and confirm the specified values in order to verify compliance with safety
standards.
|. Insulation resistance test
Confirm the specified insulation resistance or greater between
power cord plug prongs and externally exposed parts of the set
(RF terminals, antenna terminals, video and audio input and out-
put terminals, microphone jacks, earphone jacks, etc.). See
table below.
2. Dielectric strength test
Confirm specified dielectric strength or greater between power
cord plug prongs and exposed accessible parts of the set (RF
terminals, antenna terminals, video and audio input and output
terminals, microphone jacks, earphone jacks, etc.). See tabel
below.
3. Clearance distance
When replacing primary circuit components, confirm specified
clearance distance (d), (d') between soldered terminals, and bet-
ween terminals and surrounding metallic parts. See table below.
4. Leakage current test
Confirm specified or lower leakage current between B (earth
ground, power cord plug prongs) and externally exposed accessi-
bie parts (RF terminals, antenna terminals, video and audio
input and output terminals, microphone jacks, earphone jacks,
etc.).
Measuring Method: (Power ON)
Insert load Z between B (earth ground, power cord plug prongs)
and exposed accessible parts. Use an AC voltmeter to measure
across both terminals of load Z. See figure and following table.
