cassette deck

Hello, I am trying to keep my oem stereo going in my 96 3.0l. One day the stereo completely stopped working aside from the clock if you pressed the button. I took it out, found a leaking capacitor on the circuit board, and replaced it. There was also a circuit board trace that was eaten away...

my cassette deck recently stopped working in my truck, and I'm having a hard time figuring out how to fix it. a tape will oad like normal, but it wont depress at all.
