ESD
All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wristband with resistance. Keep components and tools at this potential.
Alle IC´s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.
f
ATTENTION
Tous les IC et beaucoup d´autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévite pourrait être considérablement écourtée par le fait qu´aucune précaution nést prise à leur manipulation. Lors de réparations, s´assurer de bien être relié au même potentiel que la masse de l´appareil et enfileer le bracelet serti d´une résistance de sécurité. Veiller à ce que les composants ainsi que les outils que l´on utilise soient également à ce potentiel.

WARNUNG
i
AVVERTIMENTO
Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kann die Lebensdauer drastisch reduzieren. Sorgen Sie dafür, daß Sie im Reparaturfall über ein Pulsarmband mit Widerstand mit dem Massepotential des Gerätes verbunden sind. Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem Potential.
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevità potrebbe essere fortemente ridatta in caso di non osservazione della più grande cauzione alla loro manipolazione. Durante le riparationi occorre quindi essere collegato allo stesso potenziale che quello della massa delápparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

DISMANTLING INSTRUCTIONS
Dismantling the Top Cover
· Remove 9 screws as shown in picture 1. · Release side walls on bottom and raise top cover upwards.
Manual Opening the Tray
In case the loader is defect or cannot be opened electrically, proceed as follows: · The tray can be released by means of screwdriver. The locking slider of the tray can be accessed through a slot on the bottom side of the set. To prevent dust coming into the drive this slot is covered by an adhesive tape on the cabinet of the drive (see picture 4). Push through this adhesive tape and move the white pin of the slider to the left side (see picture 5). The tray will move out a bit and is now released. · Pull the tray out. Make sure that a new adhesive tape has been applied to the drive when the repair is finished!

LEAD FREE PRODUCED SET
This set is manufactured with lead-free production technology. This is also indicated by the PHILIPS-lead-free logo you find on the printed boards. The set is produced with lead-free solder-alloy as well as with lead-free sub-parts. It can be considered as lead-free. Due to this fact some rules have to be respected by the workshop during a repair: · Use only lead-free soldering-tin Philips SAC305 with order code 0622 149 00106. If lead-free solder-paste is required, please contact the manufacturer of your solder-equipment. · Use only adequate solder tools applicable for lead-free soldering-tin. · Adjust your solder tool so that a temperature around 217° 220° is reached at the solder joint. · Do not mix lead-free soldering-tin with leaded soldering-tin. This would lead to unreliable solder joints. · On our website http://www.atyourservice.ce.philips.com you find more information to aspects of lead-free technology BGA-de-/soldering, heating-profiles of BGAs used in Philips-sets, and others.

NTC Front: sensor for ambient temperature, located on Display board. NTC Amp(lifier): sensor for the temperature of the heatsink on the Power Amplifier board. The signals NTC_Front and NTC_Amp are compared with a special algorithm and result in the control signal Set_Fan_Ctrl which controls the speed of the set fan. In each test step of the temperature test the speed of the set fan can be set in four steps.

Press S or T button and select AUD TEST
Press PLAY button. Y
The AUDIO TEST is derived from a factory test defined to test the Combi board as stand alone test object. During the relevant test steps the Audio tuner and the DVD module are not switched on. Input signals have therefore to be fed in directly at the dedicated sockets on the Combi board. The defined input signals stated in table 4 are intended for quantitative measurements of the different software settings. For a quick test in repair workshops it is recommended to use test step 1. Test step 1 produces output on 6 channels. XX stands for the number This allows either a simple check of the signal path from of the test step acc. Line in 1-socket to Line out-socket and the headphone table 4. amplifier or a complete check of all 6 channels inclusive the power amplifiers. At the beginning of the Audio test the user settings are set to following default values: Volume: 10 (-33dB) Bass/Treble: flat Loudness: off Clear Voice: off Bass ALC: on All speaker outputs: Volume 0dB During test step1 manual setting of the sound parameters is possible. When test step 1 is left the default values will be restored.

5. Diagnostic Software
Due to the complexity of the DVD recorder, the time to find a defect in the recorder can become long. To reduce this time, the recorder has been equipped with Diagnostic and Service software (DS). The DS offers functionality to diagnose the DVDR hardware and tests the following: · Interconnections between components · Accessibility of components · Functionality of the audio and video paths This functionality can be accessed via several interfaces: 1. End user/Dealer script interface 2. Command Interface 5.1.2 Structure

5.1.1
End User/Dealer Script Interface
Description The End user/Dealer script interface gives a diagnosis on a stand alone DVD recorder. During this mode, a number of hardware tests (nuclei) are automatically executed to check if the recorder is faulty. The diagnosis is simply a "fail" or "pass" message. If the message "FAIL" appears on the display, there is apparently a failure in the recorder. If the message "PASS" appears, the nuclei in this mode have been executed successfully. There can be still a failure in the recorder because the nuclei in this mode don't cover the complete functionality of the recorder.

Command overview Digital Board Chrysalis Below you will find an overview of the nuclei, their numbers, and their error codes. This overview is preliminary and subject to modifications.
Figure 5-7 Enter "Y" to program a safe string. With this automatically generated string the board will work in principle but it has to be checked if all board settings were detected correctly.
