DAEWOO ELECTRONICS DV-F562 Series, Service Manual

• 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, perform the following tests and confirm the specified values in order
to verify compliance with safety standards.

1. Insulation resistance test

Confirm the specified insulation resistance between power cord plug prongs and externally exposed parts of the set
(RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) is
greater than values given in table 1 below.

2. Dielectric strength test

Confirm specified dielectric strength 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.) is
greater than values given in table 1 below.

3. Clearance distance

When replacing primary circuit components, confirm
specified clearance distance (d), (d') between soldered
terminals, and between terminals and surrounding
metallic parts. See table below.

locality.

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 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 accesible parts. Use an AC
voltmeter to measure across both terminals of load Z.
See figure2 and following table.

locality.
