PRODUCT SAFETY SERVICING GUIDELINES FOR DVD+VCR PRODUCTS

1-4
SERVICING PRECAUTIONS
CAUTION: Before servicing the VCR+DVD covered by this
service data and its supplements and addends, read and
follow the SAFETY PRECAUTIONS. NOTE: if unforeseen
circumstances create conflict between the following servicing
precautions and any of the safety precautions in this
publications, always follow the safety precautions.
Remember Safety First :
General Servicing Precautions
1.Always unplug the VCR+DVD AC power cord from the AC
power source before:
(1) Removing or reinstalling any component, circuit board,
module, or any other assembly.
(2) Disconnecting or reconnecting any internal electrical
plug or other electrical connection.
(3) Connecting a test substitute in parallel with an
electrolytic capacitor.
Caution : A wrong part substitution or incorrect polarity
installation of electrolytic capacitors may result in an
explosion hazard.
2.Do not spray chemicals on or near this VCR+DVD or any of
its assemblies.
3.Unless specified otherwise in this service data, clean
electrical contacts by applying an appropriate contact
cleaning solution to the contacts with a pipe cleaner, cotton-
tipped swab, or comparable soft applicator.
Unless specified otherwise in this service data, lubrication of
contacts is not required.
4.Do not defeat any plug/socket B+ voltage interlocks with
which instruments covered by this service manual might be
equipped.
5.Do not apply AC power to this VCR+DVD and/or any of its
electrical assemblies unless all solid state device heat sinks
are correctly installed.
6.Always connect the test instrument ground lead to an
appropriate ground before connecting the test instrument
positive lead. Always remove the test instrument ground
lead last.
Insulation Checking Procedure
Disconnect the attachment plug from the AC outlet and turn
the power on. Connect an insulation resistance meter (500V)
to the blades of the attachment plug. The insulation resistance
between each blade of the attachment plug and accessible
conductive parts (Note 1) should be more than 1Mohm.
Note 1: Accessible Conductive Parts include Metal panels,
Input terminals, Earphone jacks,etc.
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged
easily by static electricity. Such components commonly are
called Electrostatically Sensitive (ES) Devices. Examples of
typical ES devices are integrated circuits and some field effect
transistors and semiconductor chip components.
The following techniques should be used to help reduce the
incidence of component damage caused by static electricity.
1.Immediately before handling any semiconductor component
or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known earth
ground. Alternatively, obtain and wear a commercially
available discharging wrist strap device, which should be
removed for potential shock reasons prior to applying power
to the unit under test.
2.After removing an electrical assembly equipped with ES
devices, place the assembly on a conductive surface such
as aluminum foil, to prevent electrostatic charge buildup or
exposure of the assembly.
3.Use only a grounded-tip soldering iron to solder or unsolder
ES devices.
4.Use only an anti-static solder removal device. Some solder
removal devices not classified as “anti-static” can generate
electrical charges sufficient to damage ES devices.
5.Do not use freon-propelled chemicals. These can generate
an electrical charge sufficient to damage ES devices.
6.Do not remove a replacement ES device from its protective
package until immediately before you are ready to install it.
(Most replacement ES devices are packaged with leads
electrically shorted together by conductive foam, aluminum
foil,or comparable conductive material).
7.Immediately before removing the protective material from
the leads of a replacement ES device, touch the protective
material to the chassis or circuit assembly into which the
device will be installed.
Caution: Be sure no power is applied to the chassis or
circuit, and observe all other safety precautions.
8.Minimize bodily motions when handling unpackaged
replacement ES devices. (Normally harmless motion such
as the brushing together of your clothes fabric or the lifting
of your foot from a carpeted floor can generate static
electricity sufficient to damage an ES device.)

INFORMATION ABOUT LEAD-FREE SOLDERING
Philips CE is producing lead-free sets from 1.1.2005 onwards.
INDENTIFICATION:
Regardless of special logo (not always indicated)
one must treat all sets from 1 Jan 2005 onwards, according next rules:
Example S/N:
Bottom line of typeplate gives a 14-digit S/N. Digit 5&6 is the year, digit 7&8 is the
week number, so in this case 1991 wk 18
So from 0501 onwards = from 1 Jan 2005 onwards
Important note: In fact also products of year 2004 must be treated in this way as long as you avoid mixing solder-alloys
(leaded/ lead-free). So best to always use SAC305 and the higher temperatures belong to this.
Due to lead-free technology some rules have to be respected by the workshop during a repair:
•Use only lead-free solder alloy Philips SAC305 with order code 0622 149 00106. If lead-free solder-paste is required,
please contact the manufacturer of your solder-equipment. In general use of solder-paste within workshops should be
avoided because paste is not easy to store and to handle.
•Use only adequate solder tools applicable for lead-free solder alloy. The solder tool must be able
* To reach at least a solder-temperature of 400°C,
* To stabilize 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 stabilized 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-fluid will be destroyed. To avoid wear-out of tips switch off un-used equipment, or reduce heat.
•Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible but PHILIPS recommends strongly to avoid
mixed solder alloy types (leaded and lead-free).
If one cannot avoid or does not know whether product is lead-free, clean carefully the solder-joint from old solder alloy
and re-solder with new solder alloy (SAC305).
•Use only original spare-parts listed in the Service-Manuals. Not listed standard-material (commodities) has to be
purchased at external companies.
•Special information for BGA-ICs:
- always use the 12nc-recognizable soldering temperature profile of the specific BGA (for de-soldering always use the
lead-free temperature profile, in case of doubt)
- lead free BGA-ICs will be delivered in so-called ‘dry-packaging’ (sealed pack including a silica gel pack) to protect the
IC against moisture. After opening, dependent of MSL-level seen on indicator-label in the bag, the BGA-IC possibly still
has to be baked dry. (MSL=Moisture Sensitivity Level). This will be communicated via AYS-website.
Do not re-use BGAs at all.
•For sets produced before 1.1.2005 (except products of 2004), containing leaded solder-alloy and components, all
needed spare-parts will be available till the end of the service-period. For repair of such sets nothing changes.
•On our website www.atyourservice.ce.Philips.com you find more information to:
* BGA-de-/soldering (+ baking instructions)
* Heating-profiles of BGAs and other ICs used in Philips-sets
You will find this and more technical information within the “magazine”, chapter “workshop news”.
For additional questions please contact your local repair-helpdesk.comparable conductive material).

VCR ELECTRICAL ADJUSTMENT PROCEDURES
1. SERVO ADJUSTMENT
1) PG Adjustment
• Test Equipment
a) OSCILLOSCOPE C) PAL MODEL : PAL SP TEST TAPE
b) NTSC MODEL : NTSC SP TEST TAPE
MODE MEASUREMENT POINT ADJUSTMENT POINT SPECIFICATION
PLAY V.Out R/C TRK JIG KEY 6.5 ±0.5H
H/SW(TP)
• Adjustment And Specification
•Adjustment Procedure
a) Insert the SP Test Tape and play.
Note - Adjust the distance of X, pressing the Tracking(+) or Tracking(-) when the “ATR” is blink after the
SP Test Tape is inserted.
b) Connect the CH1 of the oscilloscope to the H/SW(TP) and CH2 to the Video Out for the VCR.
c) Trigger the mixed Combo Video Signal of CH2 to the CH1 H/SW(TP) and then check the distance (time
difference), which is from the selected A(B) Head point of the H/SW(TP) signal to the starting point of
the vertical synchronized signal, to 6.5H ± 0.5H (412µs, 1H=63µs).
•PG Adjustment Method
a-1) Playback the SP standard tape
b-2) Press the “OK” key on the Remote control and the “REC” key on the Front Panel at the same time for
more than 5seconds, then it goes in to Tracking initial mode.
c-3) Repeat the above step(No.b-2), then it finishes the PG adjusting automatically.
d-4) Stop the playback, then it goes out to PG adjusting mode after mony the PG data.
