CTV-1015 R Service Manual - CTV-1015 SAFETY PRECAUTION 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 in this receiver is 18KV. The high voltage must not exceed 25KV. Each time a receiver requires servicing, the high voltage should be checked according to the high voltage check procedure on this manual. It is recommended that 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. 2. The only source of X-RAY RADIATION in this television is the picture tube. For continued X-RAY RADIATION protection, the replacement of tube must be exactly the same type tube as specified in the parts list. 3. Some parts in this television 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 below. 4. Serviceman - WARNING : To Reduce the Risk of Possible Exposure to X-Radiation, take X-Radiation Protective Measures(See Service Manual) For Personnel During Servicing. CAUTION : SHORT ANODE LEAD ONLY TO CHASSIS. DO NOT PLACE THIS PRODUCT ON AN UNSTABLE CART, STAND, TRIPOD, BRACKET, OR TABLE. THE PRODUCT MAY FALL, CAUSING SERIOUS PERSONAL INJURY AND SERIOUS DAMAGE TO THE PRODUCT. USE ONLY WITH A CART, STAND, TRIPOD, BRACKET, OR TABLE RECOMMENDED BY THE MANUFACTURER, OR SOLD WITH THE PRODUCT. FOLLOW THE MANUFACTURER'S INSTRUCTIONS WHEN INSTALLING THE PRODUCT AND USE MOUNTING ACCESSORIES RECOMMENDED BY THE NUFACTURER. A PRODUCT AND CART COMBINATION SHOULD BE MOVED WITH CARE. QUICK STOPS, EXCESSIVE FORCE, AND UNEVEN SURFACES MAY CAUSE THE PRODUCT AND CART COMBINATION TO OVERTURN. SAFETY PRECAUTION WARNING : Service should not be attempted by anyone unfamiliar with the necessary precautions on this television. The followings are the necessary precautions to be observed before servicing. 1. Since the chassis of this television is directly connected to the AC power line (Hot chassis),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 handing the picture tube. The picture tube is highly evacuated and, if broken, glass fragments will beviolently expelled. Use shatterproof goggles and keep picture tube away from the body while handing. 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 resistor-capacitor network, etc. 4. Before returning the set to the customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet such as terminals, screwheads, metal overlays control shafts, etc. to insure t
