conform the specified values in order to verify compliance with safety standards.
1-1. Insulation resistance test
Confirm the specified insulation resistance between power cord plug prong and externally exposed
parts of the set (video and audio input terminals, speaker out terminals etc) is greater than values
given in table 1 below.
1-2. Dielectric strengthen test
Confirm specified dielectric strengthen between
power cord plug prongs and exposed accessible
parts of the set (video and audio input terminals,
speaker out, etc) is greater than values given
table 1 below.
1-3. Clearance distance
When replacing primary circuit component, confirm specified clearance distance (d), (d’) between
soldered terminals (see Fig1), and between terminals and surrounding metallic parts. See table 1
below.
