transistor problem ?

[Caveoftreasures]

a mate gave me some advice but i want to get a general consensus.

i purchased a machine bally 1990 bugs bunny from a guy and he said the kicker wasnt working -he attempted to fix it cause the wire was loose.
he touched the wire on something other than the kicker when the machine was powered up and he now thinks the machine has a blown transistor of some description ?
could this be a very expensive fix, or a straight forward fix.any help would be great.

If only one solenoid is not working, here is your 2 levels of repair that may be needed:

1 - Driver and pre-driver transistor - straightforward
2 - driver, pre-driver transistor and maybe a 7408 IC - a bit fiddly but reasonably straightforward

You do step 1 first anyway, so step 2 is "just" swapping an IC...

I'd be carefully checking the rest of the machine, to make sure no other drivers have been taken out (flashers, lamps, other solenoids). Probably not, but check anyway
