02.PDF1. Precautions 1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields. 2. When reinstalling the chassis and its assemblies, be sure to restore all pretective devices, including : control knobs and compartment covers. 3. Make sure that there are no cabinet openings through which people--particularly children --might insert fingers and contact dangerous voltages. Such openings include the spacing between the picture tube and the cabinet mask, excessively wide cabinet ventilation slots, and improperly fitted back covers. If the measured resistance is less than 1.0 megohm or greater than 5.2 megohms, an abnormality exists that must be corrected before the unit is returned to the customer. 4. Leakage Current Hot Check (See Fig. 1) : Warning : Do not use an isolation transformer during this test. Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI C101.1, Leakage Current for Appl
03.PDF2. Reference Information 2-1 Servicing Jigs and Special Tools 2-1-1 Servicing guide 1. For this VCR chassis, the program switch and the sensors (start/end/reel) are located on the main PCB, not on the deck ass’y. 2. As long as the deck ass’y is connected to the main PCB, all repairs are possible. Important : In order to repair the main PCB without the deck ass’y connected, the X-5 chassis jig should be used. 3. To emulate the function of the sensors, connect a jumper or solder land (two point) at service option(W750) on the function-timer PCB. 4. The X-5 chassis jig can be used for the following : 1) When repairing or confirming the operation of the deck ass’y. 2) When replacing or repairing the components located under the deck ass’y. 3) When repairing the function PCB. 5. The X-5 chassis jig can not be used for the following : 1) Repairing defects in the video section. 2) Repairing defects in the audio section. 3) If the defect is related to tape speed. Note : 1) Repair may not be po
