I have a problem with my TOM....

When I start a game, the left flipper energizes. I've tried replacing the flipper opto board, but that didn't fix anything.

I've replaced the TIP102, the TIP36C and the 2N4403 transistors.

I'm still having the same problem.

What else do I need to replace?

I forgot to mention that I also replaced the flipper opto board.

Quoted from LTG:

If it goes up when you turn the game on, transistor issue.
If it goes up when you start a game - check for two diodes on the coil soldered on good. Then Tests Switch Edge - push the flipper button in slowly, two optos, first one registers on the DMD for lowers then second one registers for uppers and lane changes etc.
LTG : )

Being the impatient person that I am,,,,I went ahead and installed 2 new diodes to the new flipper coil....

Went into test edge...I'm getting nothing from the left flipper button.

Lloyd, you're a genius...

The plastic opto blades were hitting the opto switch
