COLOR TELEVISION SERVICE MANUAL MODELNO.PF21GB300 CHASSISNO.ETE-3 Please read this manual carefully before service. 1. SAFETY INSTRUCTIONS AND MAINTENANCE WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "X-RAY RADIATION PRECAUTION", "SAFETY PRECAUTION"AND "PRODUCT SAFETY NOTICE"INSTRUCTION BELOW. 1.1 X-RAY RADIATION PRECAUTION 1.1.1 The EHT must be checked every time the TV is serviced to ensure that the CRT does not emit X-ray radiation as result of excessive EHT voltage. The maximum EHT voltage permissible in any operating circumstances must not exceed the rated value. When checking the EHT, use the High Voltage Check procedure in this manual using an accurate EHT voltmeter. 1.1.2 The only source of X-RAY radiation in this TV is the CRT. The TV minimizes X-RAY radiation, which ensures safety during normal operation. To prevent X-ray radiation, the replacement CRT must be identical to the original fitted as specified in the parts list. 1.1.3 Some components used in this TV have safety related characteristics preventing the CRT from emitting X-ray radiation. For continued safety, replacement component should be made after referring the PRODUCT SAFETY NOTICE below. 1.1.4 Service and adjustment of the TV may result in changes in the nominal EHT voltage of the CRT anode. So ensure that the maximum EHT voltage does not exceed the rated value after service and adjustment. 1.2 SAFETY PRECAUTION WARNING: REFER SERVICING TO QUALIFIED SERVICE PERSONNEL ONLY. 1.2.1 The TV has a nominal working EHT voltage. Extreme caution should be exercised when working on the TV with the back removed. Do not attempt to service this TV if you are not conversant with the precautions and procedures for working on high voltage equipment. When handling or working on the CRT, always discharge the anode to the TV chassis before removing the anode cap in case of electric shock. The CRT, if broken, will violently expel glass fragments. Use shatterproof goggles and take extreme care while handling. Do not hold the CRT by the neck as this is a very dangerous practice.. 1.2.2 It is essential that to maintain the safety of the customer all power cord forms be replaced exactly as supplied from factory. 1.2.3 Voltage exists between the hot and cold ground when the TV is in operation. Install a suitable isolating transformer of beyond rated overall power when servicing or connecting any test equipment for the sake of safety. 1.2.4 When replacing ICs, use specific tools or a static-proof electric iron with small power (below 3 5W). 1.2.5 Do not use a magnetized screwdriver when tightening or loosing the deflection yoke assembly to avoid electronic gun magnetized and decrement in convergence of the CRT. 1.2.6 When remounting the TV chassis, ensure that all guard devices, such as nonmetal control buttons, switch, insulating sleeve, shielding cover, isolating resistors and capacitors, are installed on the
