 SAFETY&PRECAUTIONS
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.

4. Leakage current test
  Confirm specified or lower leakage current between
  B(earth ground, power cord plug prongs) and externally
  exposed accessible parts (RF terminals, antenna termi-
  nals, video and audio input 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 on AC voltmeter to measure across both terminals of load Z. See figure2 and
  following table.

  Leakage current ratings for selected are as
