Quoted from Chris-Socal:

Gentleman, thank you! You are correct that the audio had reverted to minimum. I still have some lights that work great in test mode but dont light at any other time: Shoot again, ball serve, and the left two tied together. Isnt it safe to assume the SCR's are fine if they come on and flash in test mode. Any additional advice for that.

Quoted from Chris-Socal:

I agree about the volatility of the lamp sockets, thats a project on my list
! but why do they work great in test mode? I think thedefog answered my question of this being the decoder. I originally assumed the driver was not receiving a signal. I reiterate, they do not light during game play or standby, but the minute you press the red button they all light up just fine. Maybe I should see if these bulbs are all controlled by the same decoder. Hmmm.
You guys are giving a new member immense attention and I cannot thank you enough.
