Resolved another issue late last night, that I was having with the slingshot on the SW CPU board

I went back to the repair I did when the POP Bumper's transistors blew to high heaven.
There were 2 IC's that I replaced and put it sockets, in case they ever blew again.
I did a bit of testing with the multimeter around the IC sockets and found that this IC socket had a bad connection:


Desoldered the socket and soldered in a new one making sure that each leg on the socket had a good connection both on top & bottom of the board.

Reinstalled into machine and BAM ! The right sling now works as it should 

A word of advice when buying IC sockets:
You can see the difference in the picture below, the one on the left is the one to go for when you need a connection on both side of the board.
I tried to get them, but where I went didn't have them, so I got the ones on the right.
If I had of got the ones on the left, I wouldn't have had any troubles.
