d.zio,

blew up a capacitor there was something wrong with the car's electrical circuit, for example:
excess voltage due to failure in the voltage regulator alternator.
reversing the battery cables, error caused by some auto electrician.
in both cases most certainly broke down the components of this
ecu.
if you can post photos with good image definition, perhaps even the distance I can help you.
i work with repairs to the ECU, I have a little experience.

What about DTC codes do you get any?

Maybe circuit is damage,because capacitor acid or short circuit.
Had this problem once and needed to confirm all circuit around.
After repair some lines ecu worked.
Confirm

Do not know if is the same like i have worked,but confirm capacitor C 108 and bad contacts in the midlle of ecu.

Your photos resolutions is a bit bad man, you should take some high resolutions ones, so the components and leads appear clearly than this.
