Space fever help

[Egames]

Hi. So about 2 weeks ago I got a space fever cocktail that doesn't work so after cleaning out many coins from the transformer and emptying (around 20 year old) rice out of the coin door I powered it up to be greeted with nothing. No sound, picture (but I have confirmed that the monitor works) and not even the coin counter works so after 2 weeks of doing nothing I was looking at the space fever when something in the power supply caught my eye. After opening it up I found 3 terminals, jumper wires and some liquid (my guess is acid) all around the bottom of the board and around a capacitor on the top corner of the board. my First question, are the terminals and jumpers original and finally is the acid from the capacitor. Thanks.
