Reply to Deck A won't play in TSP2

I've been using TSP and TSP2 for quite a while and never had an issue. After a re install Deck A won't play in Vinyl mode. However, it does play with my X1 or by clicking the play button with the mouse.

I have tried everything I can believe of and concluded that the RCA cable to my left TT is bad. When I switch my right TT into deck A it plays.

The only other weird thing is the top left "ON" button for FX on my X1 doesn't light up. Everything else on the X1 works perfectly and has backlight so i am wondering if this has something to do with the issue?
