I installed the bulbs today when I got home from work. Everything is scoring properly on the display. The machine still pays out five tokens whenever a token in inserted and then does not pay out after the game is complete.

A quick question before I find someone to take the machine and have a look at the boards. What are the proper functions of the two below the coin slot. I just want to make sure they are functioning properly.

Also, what does the small light in the "IC" logo above the coin slot indicate?

I just want to make sure I understand how everything is supposed to work before taking the machine to someone for repairs.
