SERVICE MANUAL Colour Television PAL/SECAM/BG/DK Models: 14" CTV-37V10 (chasis 3401) 21" CTV-55V10 (chasis 4401) RTV servis Horvat Tel: ++385-31-856-637 Tel/fax: ++385-31-856-139 Mob: 098-788-319 CAUTION Before serving the chassis, read the "X-Ray Radiation Precaution", "Safety Precaution" and "Product Safety | Notice" on page 2 of this manual. X-RAY RADIATION PRECAUTION 1. Excessive high voltage can produce potentially hazardous X-Ray Radiation.' To avoid such hazards, the high voltage must not be above the specified limit. The normal value of the high voltage of this receiver is 24KV at zero beam current (minimum brightness) under 220V AC power source. The high voltage must not, under any circumstances, exceed 30KV. Each time a receiver requires servicing, the high voltage should be checked following the High Voltage Check procedure in this manual. It is recommended the reading of the high voltage be recorded as a part of the service record, it is important to use an accurate and reliable high voltage meter. The primary source of X-Ray Radiation in this TV Receiver is the picture tube. For continued X-Ray Radiation protection, the replacement tube must be exactly the same type tube as specified in the part list. Some parts in this receiver have special safety - related characteristics for X-Ray Radiation protection. For continued safety, parts replacement should be undertaken only after referring to the Product Safety Notice. 2. 3. 4. SAFETY PRECAUTION Warning: Service should not be attempted by anyone unfamiliar with necessary precaution on this receiver. The following are the necessary precautions observed before servicing this chassis. 1. Since the power supply circuit of this receiver is directly connected to the AC power line, an isolation transformer should be used during any dynamic service to avoid possible shock hazard. 2. Always discharge the picture tube anode to the CRT conductive coating before handling the picture tube. The picture tube is highly evacuated and if broken, glass fragment will be violently expelled. Use shatter proof goggles and keep picture tube away from the unprotected body while handling. 3. When replacing a chassis in the cabinet, always be certain that all the protective devices are put back in place, such as: non-metallic control knobs, insulating covers, shields, isolation resistorcapacitor network etc. 4. When replacing parts or circuit boards, disconnect the power cord. 5. When replacing a high wattage resistor (Metal oxide film resistor) on circuit board, keep the resistor 10mm (1/2in.) away from circuit board. 6. Connection wires must be kept away from components with high voltage or high temperature. 7. If any fuse in this TV receiver is blown, replace it with the FUSE specified in the chassis part list. 8. The receiver is designed to operate with 220V(50/60Hz) AC mains. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in this chassis have special safety-related
