Osborne 01 computer smoked..

I checked the Flyback and whole Video assembly , it looks fine on inspection.. I pulled the whole unit apart and I now know its the Switching Power Supply.. 1980 by Astec components LTD. The board mesures 4 by 7inches and looks very clean, exception of the Cap that blew, The fuse is not blown either.. LIke I said I shut it down as soon as I saw smoke.. The Obvoius bad component is the Capacitor (Its cracked on has skicky stuff leaking out) The Value is 0,1uF@X , brand is Rita, GPC , 250V-MP On inspection this looks to be the only bad part.. It is next to, in fact touching against I think a diod or transistor , its black with 3 legs (Wires) on it (GI KBP-10 8210).. I am not a professional board level techniction, but I do have alot of experiance soldering and working with electronic components.. I have basic tools like: Soldering iron, Ohm meter.. I should be able to reoair this myself with (Like the song goes) "A Little help So What do you think? Should I just replace the Bad Cap and plug it in again? Do you think it blew because of another shorted part ? Like I said the unit was still working when I shut it down, it was smoking like crazy tho.. It looks like the standard voltages +12, -12, Com, +5 noted on the circuit board.. Can anyone help...??? Thanks for your help... Phil Clayton
