HANDLING CHIP COMPONENTS

	1-4
GB WARNING	ESD	NL WAARSCHUWING

All ICs and many other semi-conductors 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 wrist wrap with resistance. Keep components and tools also 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 verminderen. 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 longévité pourrait être considérablement écourtée par le fait qu’aucune précaution n’est prise à leur manipulation.

Lors de réparations, s’assurer de bien être relié au même potentiel que la masse de l’appareil et enfiler 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.

GB

D WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD).

Unsorgfältige Behandlung im Reparaturfall kan die Lebensdauer drastisch reduzieren. Veranlassen Sie, dass Sie im Reparaturfall über ein Pulsarmband mit Widerstand verbunden sind mit dem gleichen Potential wie die Masse des Gerätes.

Bauteile und Hilfsmittel auch auf dieses gleiche Potential halten.

I AVVERTIMENTO

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 riparazioni occorre quindi essere collegato allo stesso potenziale che quello della massa dell’apparecchio tramite un braccialetto a resistenza.

Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used.

“Pour votre sécurité, ces documents doivent être utilisés par des spécialistes agréés, seuls habilités à réparer votre appareil en panne”.

NL

Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in

zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen, identiek aan de gespecificeerde, worden toegepast.

F

Les normes de sécurité exigent que l’appareil soit remis à l’état d’origine et que soient utiliséés les piéces de rechange identiques à celles spécifiées.

D

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten. Der Original zustand des Geräts darf nicht verändert werden; für Reparaturen sind Original-Ersatzteile zu verwenden.

GB Warning !

Invisible laser radiation when open.

Avoid direct exposure to beam.

S Varning !

Osynlig laserstrålning när apparaten är öppnad och spärren är urkopplad. Betrakta ej strålen.

I

Le norme di sicurezza esigono che l’apparecchio venga rimesso nelle condizioni originali e che siano utilizzati i pezzi di ricambio identici a quelli specificati.

"After servicing and before returning set to customer perform a leakage current measurement test from all exposed metal parts to earth ground to assure no shock hazard exist. The leakage current must not exceed 0.5mA."

SF Varoitus !

Avatussa laitteessa ja suojalukituksen ohitettaessa olet alttiina näkymättömälle laserisäteilylle. Älä katso säteeseen!

DK Advarse !

Usynlig laserstråling ved åbning når sikkerhedsafbrydere er ude af funktion. Undgå udsaettelse for stråling.

DISMANTLING INSTRUCTIONS

Dismantling of the Front Panel assembly

1)Open the Tray and remove the tray cover assy (pos 101- 19-1 + 101-19-5) and remove it as shown in figure 1.

Note: The Tray can be manually open by inserting a minus screw driver (approximately 9mm) and push lever in the direction shown in figure 2.

2)Loosen the 5 screws to dismantle the Top Cover (pos 252)

-2 screws on each side

-3 screws on the Rear Panel (pos 251).

3)Uncatch 6 catches (2x on side & 2x on the bottom and 2x on the Loader C2) to slide the Front Panel assembly (pos 101) as per figure 3.

DISMANTLING INSTRUCTIONS

Dismantling of the PSU, Loader Mechanism & MPEG board

1)Remove the Tray cover as per instruction to remove the Front panel assembly

2)Loosen 4 screws A and 2 catches C2 to remove the Loader Module (pos 1002) as per figure 3.

3)Loosen 5 screws (2x screw B and 3x screw E) to remove the MPEG board (pos 1003) as per figures 3 and 4.

4)Loosen 2 screws D and 2 catches C1 to remove the PSU board (pos 1001).

DVD Region code

There is only 1 version of software (for region 2) in this range, therefore no special re-programming is required. However, it is possible to change the region code but do note that selecting a different region code will not change the existing setting like TV system, output format, etc.

Region code change is done as follows:

1)Power up the set and open tray.

2)Press <System Menu> button

3)Press <Stop> <Previous> follow by <X> buttons on the

Remote control.

where x = numeric 1 to 6 denoting the regions below:

1	=	USA
2	=	Europe

3= Asia Pacific

4= Australia, New Zealand, Latam

5= Russia, India

6= China

Procedure to view Software version and Region code

1)Power up the set

2)Press <System Menu> button on the Remote control.

3)Press <Stop> <Previous> and <Next> buttons on the Remote control.

3) The TV screen will shows: VERSION : DP330.4.19 REG : 2

Region code Application software (backend)

Procedure to upgrade software

1)Power up the set and open tray.

2)Place upgrade CD-ROM onto tray and close it.

3)The FTD on the set [and TV screen] will response and display the following:

-LOAD [TV screen shows: DISC LOADING]

-DATA [TV screen shows: READ]

-UPGRADE [TV screen shows: UPGRADING

followed by DONE when it is completed]

4)The tray opens for you to remove the CD-ROM and the set switches to Standby.

5)The whole process should last less than 5 minutes.
