A1200 Short circuited pin 150 -12v with pin 149 +12v repair

Hello there,this afternood i was installing the acard scsi to ide to CF adaptoer to my blizzard 1230-iv scsi and the metal shield touched to pins of the blizzy.the pin 150 which is actually -12v and pin 149 which is +12v.a line was burnt from pin 150 to a capacitor near CIA .The amiga 1200 powers on OK , but it freezes moments after i use the mouse.I resolder the trace ,still same problem.Is the CIA to blame,shall i replace them or there must have be done some more damage and i shall buy a new motherboard?Also i noticed that the big black barrel capacitor near the cia has enlarged itself,can this problem be because i need to recap my mobo?what shall i do and where i could find CIA chips?
thank you .

If a capacitor has a bulged cap or 'wet' feet it needs to be replaced. Can't guarantee that it solves the problem tho...

Id replace the one cap first. Then if that doesn't fix it send it to a professional to attempt to repair and replace all the caps, if they find the problem.  Alternatively you could source a used or refurbished A1200 for probably close to the same price of the repairs and postage. I know it doesn't help but I have thick insulation tape on the edge of the shielding next to the edge connector.

After  some years of inactivity and having changed the caps by a professional , the blizzard was not working.It would lock up after 4 minutes of usage.Every time.It turns out that all i had to do was to remove the E123C and E125C as per Ians instructions and now the amiga works like new.Note than back in 1994 when i bought new the A1200 and the blizzard 1230iv it was working with the resistors in place.Salute!
