My trusty 2600 fire button issues

Hey guys,

Sadly my 2600 heavy sixer (Sunnyvale ca) randomly started having the fire button always on issue. It worked totally fine a few months ago and has been sitting in a box. I was getting ready to give it to a friend and I wonder if static shock killed the input chip. I did also find an iffy cap in there, does it look bad to y'all?

I read about testing pin 6, I need to get around to that..

This thing has been the most reliable console I've ever had other than this!
