19R-M100 19R-M100S IMPORTANT SERVICE SAFETY PRECAUTION Ë Service work should be performed only by qualified service technicians who are thoroughly 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.
PAGE 3
19R-M100 19R-M100S 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.

19R-M100 19R-M100S 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.

19R-M100 19R-M100S 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 adjusment is required. To enter the service mode and exit service mode. While pressing the Vol-up and Ch-up buttons at the sametime, plug the AC cord into a wall socket. Now, the TV set is switched on and enters the service mode.
