NSM prestige ES160

hi everyone new to the group hopefully some one can point me in the right direction
the central was blowing fuse si2 , i found a shorted capacitor and replaced the 4 just up above that then i put it all back together fired it up and noticed now the display works with error c message displayed i looked again at central unit and discovered now si6 blew so no 56v led #101 and no 16v led #204 any ideas on what to do now i have checked all caps and checked diodes in circuit and checked resistor in relation to that circuit
Thank you for your Time, Tim
