All lcs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce lite
drastically-
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.
Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specmed,
be used
Safety components are marked by the symbol A.
. Roule the wire trees correctly and fix them with the 1'
mounted cable clamps.
. Check the insulation of the AC Power lead for external 2'
damage.
. Check the strain relief of the AG Power cord for proper 3'
function.
. Check the electrical DC resistance between the AC Power
Plug and the secondary side (only for sets which have a AC
Power isolated power supply): 4.
CLASS 1
LASER PRODUCT
Unplug the AC Power cord and connect a wire
between the two pins of the AC Power plug.
Set the AC Power switch to the'on" position (keep the
AC Power cord unplugged!).
Measure the resistance value between the pins ol the
AC Power plug and the metal shielding of the tuner or
the aerial connection on the set. The reading should be
larger than 4.5 Mohm (For U.S. it should be between
4.2 Mohm and 12 Mohm).
Switch'otf'the set, and remove the wire between the
two pins of the AC Power plug.
Check the cabinet tor defects, to avoid touching of any
inner parts by the customer.
