1.1.2 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 compli-
ance with safety standards.

(1) Insulation resistance test

Confirm the specified insulation resistance or greater be-
tween  power  cord  plug  prongs  and  externally  exposed
parts of the set (RF terminals, antenna terminals, video and
audio input  and  output  terminals,  microphone  jacks, ear-
phone jacks, etc.).See table 1 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 Fig.1-1-11 below.

(3) Clearance distance

When replacing primary circuit components, confirm spec-
ified clearance distance (d), (d') between soldered termi-
nals,  and  between  terminals  and  surrounding  metallic
parts. See Fig.1-1-11 below.

Fig.1-1-8

(4) Leakage current test

Confirm specified or lower leakage current between earth
ground/power cord plug prongs and externally exposed ac-
cessible parts (RF terminals, antenna terminals, video and
audio input  and  output  terminals,  microphone  jacks,  ear-
phone jacks, etc.).
Measuring  Method  :  (Power  ON)Insert  load  Z  between
earth  ground/power  cord  plug  prongs  and  externally  ex-
posed accessible parts. Use an AC voltmeter to measure
across both terminals of load Z. See Fig.1-1-9 and follow-
ing Fig.1-1-12.

Fig.1-1-9

(5) Grounding (Class 1 model only)

Confirm specified or lower grounding impedance between
earth  pin  in  AC  inlet  and  externally  exposed  accessible
parts  (Video  in,  Video  out,  Audio  in,  Audio  out  or  Fixing
screw etc.).Measuring Method:
Connect milli ohm meter between earth pin in AC inlet and
exposed accessible parts. See Fig.1-1-10 and grounding
specifications.
