every components mostly connected in ckt through one end ground.(2) all vhf&uhf sets are positively ground.(3) to check the gronded components we have to remove it and check.(4) in simple proceedure coil to be check for continuity,capacitor to be checked for short&likage,diode to be checked for open or short,resistance to be checked for ohmic value.In ckt capacitors mostly work for the filtering action & leading laginng current.In rf section capacitors works for the frequency resonance,by pass the spikes ect.
