DO NOT CHANGE ANY MODULE UNLESS THE SET IS SWITCHED OFF The mains supply part of the switch mode power supply�s transformer is live. Use an isolating transformer. The receiver complies with the safety requirements. SAFETY PRECAUTIONS The service of this TV set must be carried out by qualified persons only. 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 fused 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 C808 before changing IC841 or other components in primary side of the SMPS part. Measurements: Voltage readings and oscilloscope traces are measured under the following conditions: Antenna signal�s level is 60dB at the color bar pattern from the TV pattern generator. (100% white, 75% color saturation) Brightness, contrast, and color are adjusted for normal picture performance. Mains supply, 220VAC, 50Hz.
