SERVIGE AIDS
@ wARNTNG
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.

. On our website you find more information to:
* BGA{er'soHering (+ baking instuctions)
* Heatingiprofiles of BGAs and other lCs used in Philips-sets
* Lead free
You will find this and more tecfinical information within the "magazine", chapter'workshop news'.
For additional questions please contact your local repair-helpdesk
SERVICE INSTRUCTION
Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to
the following points:

CUSTOMER INFORMATION
It is proposed to add an addendum sheet to the set which
informs the customer that the set has been checked
carefully - but no fault was found.
The problem was obviously caused by a scratched, dirty or
copy-protected CD. ln case problems remain, the customer
is requested to contact the workshop directly.
The lens cleaning (method ) should be mentioned in the
addendum sheet.
The final wording in national language as well as the printing
is under responsibility of the Regional Service Organizations
Because the material of the lens is synthetic and coated
with a special anti-reflectivity layer, cleaning must be done
with a non-aggressive cleaning fluid. lt is advised to use
"Cleaning Solvent
The actuator is a very precise mechanical component and
may not be damaged in order to guarantee its full function.
Clean the lens gently (don't press too hard) with a soft and
clean cotton bud moistened with the special lens cleaner.
The direction of cleaning must be in the way as indicated in
the picture below.
