SHOCK, FIRE HAZARD SERVICE TEST :
CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and controls and chassis bottom. Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and verified before it is return to the user/customer. Ref. UL Standard No. 1492.

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 elektrostatische 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.

AVVERTIMENTO

Tous les IC et beaucoup d'autres semiconducteurs sont sensibles aux d�charges statiques (ESD). Leur long�vit� pourrait �tre consid�rablement �court�e par le fait qu'aucune pr�caution n'est prise a leur manipulation. Lors de r�parations, s'assurer de bien �tre reli� au m�me potentiel que la masse de l'appareil et enfiler le bracelet serti d'une r�sistance de s�curit�. Veiller a ce que les composants ainsi que les outils que l'on utilise soient �galement a ce potentiel.

Alle IC und viele andere Halbleiter sind empfindlich gegen elektrostatische Entladungen (ESD). Unsorgf�ltige Behandlung bei der Reparatur kann die Lebensdauer drastisch vermindern. Sorgen sie daf�r, das Sie im Reparaturfall �ber ein Pulsarmband mit Widerstand mit dem Massepotential des Ger�tes 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 longevita potrebbe essere fortemente ridatta in caso di non osservazione della piu 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.

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

D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten. Der Originalzustand des Gerats darf nicht verandert werden. Fur Reparaturen sind Original-Ersatzteile zu verwenden.

NL
Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkelijke toestand wordt terug gebracht en dat onderdelen, identiek aan de gespecifieerde worden toegepast.

I
Le norme di sicurezza esigono che l'apparecchio venga rimesso nelle condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli specificati.

F
Les normes de s�curit� exigent que l'appareil soit remis a l'�tat d'origine et que soient utilis�es les pi�ces de rechange identiques � celles sp�cifi�es.

SHOCK, FIRE HAZARD SERVICE TEST: CAUTION: After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and the face or Front Panel of product and controls and chassis bottom, Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and verified before return to user/customer. Ref.UL Standard NO.1492. NOTE ON SAFETY: Symbol : Fire or electrical shock hazard. Only original parts should be used to replace any part with symbol Any other component substitution(other than original type), may increase risk or fire or electrical shock hazard.

Warning for powersupply on position (PH16)
The primary side of the powersupply including the heatsink carries live mains voltage when the player is connected to the mains even when the player is swiched off ! This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing the player. Service personnel have to take precautions to prevent touching this area or components in this area . The primary side of the powersupply has been indicated with a lightning stroke and a stripe-marked printed on the printed wiring board Note: The screws on the mechanism of the ASD1 module (position 001M in on the exploded view drawing) may never be touched removed or re-adjusted. Handle the ASD1 module with care when the unit has to be exchanged! The mechanism of the ASD1 module is very sensative for dropping or shocks.

3.1.1 Switched Mode Power Supply Unit PZ03
This power supply unit is not repairable and must be exchanged completely in case of failure. A new power supply can be ordered with codenumber QW12922150 (3104 129 22150).

3.1.2 SACD module
This module can be repaired as follows: 1. The loader and DVD-M(echanism) is one assembly (VAL6011) item 81. This assembly is a not repairable unit and must be exchanged completely in case of failure. A new unit can be ordered with codenumber QE02361104 (9305 023 61104). 2. The mono board has to be repaired down to component level. Repair handling of the monoboard requires a workshop with sophisticated desoldering tools. Figure 3-3
