I just finished a recaping 2 4600's, Discgolfer72 is right ther fairly strait forward once you get it apart start by discharging the tube, then remove the 2 screw's on the left hand side, you should be able to loosen all the cables that attach the tube to the chassis then remove the screw on the right had side of the chassis that hold's the flyback. now you should be able to pull the chassis right out and stick it on your bench. Then remove the 4 screw's that hold the bottom place on and desolder the horz width coil this will give you acess to the solder side of the pcb. First thing is to remove the daughter boards start by remove the black plastic retainer should just have to clip a zip tie. be carefull when removing the daughter boards the connections on the bottom can get brittle over 30yrs. replace the caps on the main chassis and there are 2 on the regulator board then replace all the caps on bothe daughter boards. Before you put it back together the connectors on the daughter boards that plug in to the main chassis there nutorious for problems also solder the opposite side on the connector on the main pcb. plus it would'nt hurt to check the flyback and drive transformer for loose connections. then reasemble the monitor. you'll have to realighn it cause thing will change!!!! for the better
