Important Safety Notice !!  \nMany electrical and mechanical parts in this chassis have special safety-related characteristics.  \nThese parts are identified by in the Schematic Diagram and Replacement Parts List.  \nIt is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent Shock, Fire, or other Hazards.  \nDo not modify the original design without permission of manufacturer.  \nLeakage Current Hot Check (See below Figure)  \nPlug the AC cord directly into the AC outlet.  \nDo not use a line Isolation Transformer during this check.  \nConnect 1.5K/10watt resistor in parallel with a 0. 15uF capacitor between a known good earth ground (Water Pipe, Conduit, etc. ) and the exposed metallic parts.  \nMeasure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity.  \nReverse plug of the AC cord into the AC outlet and repeat AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS, which is, corresponds to 0.5mA.  \nIn case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.  \nLeakage Current Hot Check circuit  \n| PDI-P23LCD SERVICE MANUAL | PAGE:3 |\n| --- | --- |\n\nSERVICING PRECAUTIONS  \nCAUTION!!  \nBefore servicing receivers covered by this service manual, read and follow the SAFETY PRECAUTIONS on page 2 of this publication.  \nGeneral Servicing Precautions  \n1.Always unplug the receiver AC power cord from AC power source before;  \nⓐRemoving or reinstalling any component, circuit board module or any other receiver assembly.ⓑDisconnecting or reconnecting any receiver electrical plug or other electrical connection.ⓒConnecting a test substitute in parallel with an electrolytic capacitor in the receiver. CAUTION!! A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in an explosion harzard.
