CHANGE WITHOUT NOTICE.  \nSERVICE NOTES  \n## GENERAL SERVICING PRECAUTIONS\n\n-CAUTION-  \nBefore attempting to service the monitor,dis-connect(or turn off)the external power supply;then,as an added precaution,discharge the CRT2nd anode before handling any high voltagecomponents.In addition,be sure to observeall safety warnings and service notes in thefront of this manual.  \nWhen it is necessary to disconnect the deflection yoke,and/or CRT socket leads,pull their small female pins straightout without any back and forth rocking motion.Thiswill prevent,or at least minimize deforming male pinsand/or breaking their solder connections.  \nUse caution around the heat sink of the horizontal outputtransistor.The heat sink is at the same potential as thetransistor collector.During normal operation with signalinput present,the horizontal heat sink has 165 volt P-Ppulses(with respect to system ground).  \n## GENERAL SUBSTITUTION OF PARTS\n\nWhen components need be replaced,order Motorola re-placement parts oniy.Avoid using other substitute semi-conductor devices as these can cause system performancedegradation.In the event of failure,and the need for emer-gency system restoration,generic substitution of semicon-ductor devices used are provided as an aid on the SchematicDiagram and Parts List.  \n## COMPONENT REMOVAL\n\nDue to the nature of solid state devices such as integratedcircuits (IC's),and etched printed circuit cards,special de-soldering tools and IC removing techniques should be used.Care should be exercised not to damage the printed circuitcard,break or lift the copper foil,and create cold solderconnections.  \nntegrated circuits are very reliable components and shouldnot be replaced until all checks have proven definitely thatthe IC is the defective component.Removal of the IC istime consuming and often careless or sloppy soldering tech-niques can cause additional problems.  \n### CIRCUIT TRACING\n\nFor ease in troubleshooting,circuit card components aremounted on one side,with foil circuitry on the reverse sideof the circuit card.Schematic reference symbols and num-bers are screened on both sides of the circuit card to help  \nlocate and identify circuit components during trouble-shooting.  \nFamiliarize and study the attached Schematic
