SAFETY CHECK AFTER SERVING
Examine the area surrounding the repaired location for damage or deterioration. Observe that screw,
parts and wires have been returned to original positions. Afterwards, perform the following tests and con-
form the specified values in order to verify compliance with safety standards.
1. Insulation resistance test
Confirm the specified insulation resistance between power cord plug prong and externally exposed
parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, micro-
phone jacks, earphone jacks, etc.) is greater than values given in table 1 below.
2. Dielectric strengthen test
Confirm specified dielectric strengthen between
power cord plug prongs and exposed accessible parts
of the set (RF terminals, antenna terminals, video and
audio input output terminals, microphone jack, ear
phone jacks, etc.) is greater than values given table 1.
3. Clearance distance
When replacing primary circuit component, confirm specified clearance distance (d), (d
’
) between sol-
dered terminals, and between terminals and surrounding metallic parts. See table below.
