WARNING
GB
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.
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.

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.
WAARSCHUWING
NL
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.
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.
GB
Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used.
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.
“Pour votre sécurité, ces documents doivent être utilisés par des spécia­listes agréés, seuls habilités à réparer votre appareil en panne”.

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."

Repair Hints
Figure 14
1) During repair it is possible to disconnect the ECO6 Tuner Board completely unless the fault is suspected to be in that area. This will not affect the performance of the rest of the set.
2) The flex cables are very fragile, care should be taken not to damage them during repair. After repair, be very sure that the flex cables are inserted properly into the flex sockets before encasing, otherwise faults may occurs.

Check the correctness of the IIC bus to the NVRAM. (This test need about 3 minutes to perform)
Check writing to the NVRAM.
Check writing to the SDRAM. (This test is executed very fast and hence user will not be able to see this display message)
Result of all the tests.
Disconnect mains cord to exit the Service Test Program.
DVD Dealer Test is used to check the flash RAM, the SDRAM, the DRAM, the NVRAM and the I2C communication.
When all the tests are passed, display shows "ALL TEST PASS". If at least one of the test fails, display shows "ALL TEST FAIL".
DVD Player Test is used to start several DVD specific tests. At the end of the test, an error code "aa-bbb cccc" (see Step15) will be shown that indicates which module(s) failed.
** User has to give a confirmation by triggering one of the following:
- If the test is OK, press "PLAY"(RC) button then follow by T (RC) button to go to the next step.
- If the test is not OK, press "RESUME"(RC) button then follow by T (RC) button to go to the next step.
Note : By pressing only the T (RC) button to go to the next step without
triggering a confirmation, the test will be assume as OK by default.
Equipment required to run the DVD Player Test:
- television set
- 6 audio speakers
- an external video source
