SERVICE MANUAL MANUEL D'ENTRETIEN WARTUNGSHANDBUCH CAUTION: Before servicing this chassis, it is important that the service technician read the "Safety Precautions and "Product Safety Notices in this service manual. " " ATTENTION: Avant d'effectuer l'entretien du chвassis, le technicien doit lire les «Prйcautions de s йcuritй» et les «Notices de sйcuritй du produit» prйsentйs dans le prйsent manuel. VORSICHT: Vor Цffnen des Gehдuses hat der Service-Ingenieur die ,,Sicherheitshinweise " und ,,Hinweise zur Produktsicherheit in diesem Wartungshandbuch zu lesen " . June 2000 1-6 Safety instructions GB Avertissements F ­ Safety regulations demand that the set be restored to its original condition and that components identical with the original types be used. Safety components are marked by the symbol ­ Les normes de sйcuritй exigent qu'aprйs rйparation I'appareil soit remis dans son йtat d'origine et que soient utilisйes les piйces de rechange identiques а celles spйcifiйes. Les composants de sйcuritй sont marquйs ! ! ­ All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during repair may reduce life drastically. When repairing, make sure that you are conneted with the same potential as the mass of the set via a wrist wrap with resistance. Keep components and tools on the same potential. ­ A set to be repaired should always be connected to the mains via a suitable isolating transformer. ­ Never replace any modules or any other parts while the set is switched on. ­ Use plastic instead of metal alignment tools. This in order to prelude short-circuit or to prevent a specific circuit from being rendered unstable. Remarks ­ The direct voltages and oscillograms ought to be measured relative to the set mass. EXCEPTION At the power supply, the DC voltages and the oscillograms at the primary side are measured to LIVE GND. ­ The direct voltages and oscillograms mentioned in the diagrams ought to be measured with a colour bar signal and the picture carrier at 503.25 MHz (C25). ­ The oscillograms and direct voltages have been measured in RECORD or PLAY mode. ­ The semiconductors, which are mentioned in the circuit diagram and in the parts lists, are fully exchangeable per position with the semiconductors in the set, irrespective of the type designation of these semiconductors. ­ Tout les IC et beaucoup d'autres semi-conducteurs sont sensibles aux dйcharger statiques (ESD).
