4QCZ1.0U LA 2. Safety Instructions, Warnings and Notes
2. Safety instructions, Warning and Notes
2.1 Safety Instructions
Safety regulation require that during a repair:
* Connect the set to the AC power via an isolation
transformer(>800 VA).
* Replace safety components, indicated by the symbol
,only by components identical to the original ones. Any other
component substitution(other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:
* Route the wire trees correctly and fix them with the mounted
cable clamps.
* Check the insulation of the AC power lead for external
damage.
* Check the strain relief of the AC power cord for proper
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):
- 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 of the AC
power plug and the metal shielding of the tuner or the aerial
connection on the set. The reading should be between 4.5M
ohm and 12M ohm.
- Switch “off” the set, and remove the wire between the two
pins of the AC power plug.
* Check the cabinet for defects, to avoid touching of any inner
parts by the customer.
2.2 Warnings
* All IC s and many other semiconductors are susceptible to
electrostatic discharge (ESD ). Careless handling during
repair can reduce life drastically. Make sure that, during
repair, you are connected with the same potential as the
mass of the set by a wristband with resistance. Keep
components and tools also at this same potential.
* Be careful during measurements in the high voltage section.
* Never replace modules or other components while the unit
is switched “on”.
* When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a circuit
becoming unstable.
2.3 Notes
General
* Measure the voltages and waveforms with regard to the
chassis (=tuner) ground( ), or hot ground( ), depending on
the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode with a color bar signal and stereo
sound (L:3 K Hz, R:1 K Hz unless stated otherwise) and
picture carrier at 475.25 M Hz for PAL, or 61.25 M Hz for
NTSC.
* Where necessary, measure the waveforms and voltages
with ( ) and without ( ) aerial signal. Measure the voltages
in the power supply section both in normal operation( ) and
in stand-by( ). These values are indicated by means of the
appropriate symbols.
* The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
semiconductors in the unit, irrespective of the type indication
On these semiconductors.
* Manufactured under license from Dolby Laboratories.
“Dolby” and the “double-D symbol”, are trademarks of Dolby
Laboratories.
Schematic Notes
* All resistor values are in ohms and the value multiplier is
often used to indicate the decimal point location(e.g. 2K2
indicates 2.2K ohm).
* Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220
ohm).
* All capacitor values are given in micro-farads(u=x ),
nano-farads(n=x10), or pico-farads (p=x10 ).
* Capacitor values may also use the value multiplier as the
decimal point indication(e.g. 2p2 indicates 2.2 pF).
* An “asterisk”(*) indicates component usage varies. Refer to
the diversity tables for the correct values.
* The correct component values are listed in the Electrical
Replacement Parts List. Therefore, always check this list
when there is any double.
Rework on BGA (Ball Grid Array) IC s
General
Although (LF) BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the power
board and replacing it with a new component. If an(LF) BGA
is removed form a power board, the solder balls of the
component are deformed drastically so the removed(LF) BGA
has to be discarded.
Device Removal
As is the case with any component that, it is essential when
removing an(LF) BGA, the board, tracks, solder lands, or
surrounding components are not damaged. To remove an(LF)
BGA, the board must be uniformly heated to a temperature
close to the reflow soldering temperature. A uniform
temperature reduces the chance of warping the power board.
To do this, we recommend that the board is heated until it is
certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the
appropriate temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the(LF) BGA. Removing an
IC often leaves varying amounts of solder on the mounting
lands. This excessive solder can be removed with either a
solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent. After the board is
properly cleaned and inspected, apply flux on the solder
lands and on the connection balls of the (LF) BGA.
NOTE: DO NOT APPLY SOLDER PASTE, AS THIS HAS
SHOWN TO RESULT IN PROBLEMS DURING RE-
SOLDERING.
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF) BGA should be
aligned under a microscope or magnifying glass. If this is not
possible, try to align the (LF) BGA with any board markers. To
reflow the solder, apply a temperature profile according to the
IC data sheet. So as not to damage neighbouring
components, it may be necessary to reduce some
temperatures and times.

to “Workshop information”. Here you will find information on how
to deal with BGA-IC s.
Lead Free Solder
Philips CE is going to produce lead-free sets(PBF) from
1.1.2005 onwards.
Lead-free sets will be indicated by the Philips-lead-free logo on
the Printed Wiring Boards(PWB):
Fig Lead-free logo
This sign normally has a diameter of 6mm, but if there is less
space on a board also 3mm is possible.
In case of double wether the board is lead-free or not(or with
mixed technologies), you can use the following method:
* Always use the highest temperature to solder, when using
SAC305(see also instructions below).
* De-solder throughly (clean solder joints to avoid mix of two
alloys).
Caution: For BGA-IC s, you must use the correct temperature
porfile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions). You will
find this and more technical information within the “Magazine”,
chapter “Workshop information”. For additional questions please
contact your local repairhelpdesk.
Due to lead-free technology some rules have to be respected by
the workshop during a repair:
* Use only lead-free soldering tin. If lead-free solder paste is
required, please contact the manufacturer of your soldering
equipment. In general, use of solder paste within workshops
should be avoided because paste is not easy to store to handle.
* Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able
- To reach at least a solder-tip temperature of 400 C°.
- To stabilise the adjusted temperature at the solder-tip.
- To exchange solder-tips for different applications.
* Adjust your solder tool so that a temperature around 360 C°-
380 C° is reached and stabilised at the solder joint. Heating
time of the solder-joint should not exceed ~4 sec. Avoid
temperatures above 400 C°, otherwise wear-out of tips will rise
drastically and flux will be destroyed. To avoid wear-out of tips,
switch “off” unused equipment or reduce heat.
* Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but Philips recommends strongly to avoid
mixed regimes. If not to avoid, clean carefully the solder-joint
from old tin and re-solder with new tin.
* Use only original spare-parts list in the Service Manuals. Not
listed standard material (commodities) has to be purchased at
external companies.
* Special information for lead-free BGA IC s : these IC s will be
delivered in so-called “dry-packaging” to protect the IC against
moisture. This packaging may only be opened short before it is
used(soldered). Otherwise the body of the IC gets”wet” inside
and during the heating time the structure of the IC will be
destroyed due to high (steam-) pressure inside the body. If the
Packaging was opened before usage, the IC has to be heated
up for some hours(around 90 C°) for drying (think of ESD-
protection!).
Do not re-use BGAs at all!
* For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will be
available till the end of the service period. For the repair of
such sets nothing changes.
Practical Service Precautions
* It makes sense to avoid exposure to electrical shock.
While some source are expected to have a possible
dangerous impact, others of quite high potential are of limited
current and are sometimes held in less regard.
* Always respect voltages.
While some may not be dangerous in themselves, they can
cause unexpected reactions - reactions that are best avoided.
Before reaching into a powered TV set, it is best to test the
high voltage insulation. It is easy to do, and is a good service
precaution.
