7N-S100, 27N-S180 CN27S10/14/18 IMPORTANT SERVICE SAFETY PRECAUTION Service work should be performed only by qualified service technicians who are throughly familiar with all safety checks and the servicing guidelines which follow: WARNING X-RADIATION AND HIGH VOLTAGE LIMITS 1. For continued safety, no modification of any circuit should be attempted. 2. Disconnect AC power before servicing. 3. Semiconductor heat sinks are potential shock hazards when the chassis is operating. 4.
27N-S100, 27N-S180 CN27S10/14/18 IMPORTANT SERVICE SAFETY PRECAUTION (Continued) • Connect the resistor connection to all exposed metal parts having a return to the chassis (antenna, metal cabinet, screw heads, knobs and control shafts, escutcheon and etc.) and measure the AC voltage drop across the resistor. AII checks must be repeated with the AC line cord plug connection reversed. (If necessary, a nonpolarized adapter plug must be used only for the purpose of completing these check.
27N-S100, 27N-S180 CN27S10/14/18 PRECAUTIONS A PRENDRE LORS DE LA REPARATION Ne peut effectuer la réparation qu' un technicien spécialisé qui s'est parfaitement accoutumé à toute vérification de sécurité et aux conseils suivants. AVERTISSEMENT LIMITES DES RADIATIONS X ET DE LA HAUTE TENSION 1. N'entreprendre aucune modification de tout circuit. C'est dangereux. 2. Débrancher le récepteur avant toute réparation. 3.
27N-S100, 27N-S180 CN27S10/14/18 PRECAUTIONS A PRENDRE LORS DE LA REPARATION (Suite) • Toucher avec la sonde d'essai les pièces métalliques exposées qui présentent une voie de retour au châssis (antenne, coffret métallique, tête des vis, arbres de commande et des boutons, écusson, etc.) et mesurer la chute de tension CA en-travers de la résistance. Toutes les vérifications doivent être refaites après avoir inversé la fiche du cordon d'alimentation.

27N-S100, 27N-S180 CN27S10/14/18 INSTALLATION AND SERVICE INSTRUCTIONS Note: (1) When performing any adjustments to resistor controls and transformers use non-metallic screwdrivers or TV alignment tools. (2) Before performing adjustments, the TV set must be on at least 15 minutes. CIRCUIT PROTECTION HIGH VOLTAGE CHECK The receiver is protected by a 4.0A fuse (F701), mounted on PWB-A, wired into one side of the AC line input.
27N-S100, 27N-S180 CN27S10/14/18 For adjustments of this model, the bus data is converted to various analog signals by the D/A converter circuit. Note: There are still a few analog adjustments in this series such as focus and master screen voltage. Follow the steps below whenever the service adjustment is required. See "Table-B" to determine, if service adjustments are required. 1. Service mode To enter the service mode and exit service mode.
