SERVICE MANUAL EU-48 48cm CTV Effective: JANUARY,2000 EU48SERV 1 DO NOT CHANGE ANY MODULE UNLESS THE SET IS SWITCH OFF The mains supply side of the switch mode power supply transformer is live. Use an isolating transformer. The receivers fulfill completely the safety requirements. Safety precautions: Servicing of this TV should only be carried out by a qualified person. - Components marked with the warning symbol on the circuit diagram are critical for safety and must only be replaced with an identical component. - Power resistor and fusable resistors must be mounted in an identical manner to the original component. - When servicing this TV, check that the EHT does not exceed 26kV. TV Set switched off: Make short-circuit between HV-CRT clip and CRT ground layer. Short C804 (150mF) before changing IC802 or other components in primary side of SMPS. Measurements: Voltage readings and oscilloscope traces are measured under following conditions. Antenna signal 60dB from colourbar generator. (100% white, 75% colour saturation) Brightness, contrast, colour set for a normal picture. Mains supply, 220VAC, 50Hz.
