My White Water is causing trouble again. Both the knocker and outhole solenoids are engaging immediately upon start up and stay on until F105 blows after about 3 seconds.

I've replaced the TIP36C transistor on the power driver board for the outhole, and that did not fix the issue. After replacement, I did notice the 1N4004 diode just under the transistor smoke. I'm planning on replacing the diode, but I need to procure the parts.

Is anyone else familiar with this issue? Is it possibly the TIP102? Really wish I could play the game; it's been full of problems since I've purchased it.

Easy to check the TIP102, it is likely bad.

Probably the tip 102 but also could be a bad coil in my experience

Check the TIP102, I'd probably start there.

If you've got a logic probe, go back to the 74ls374 that toggles the pre driver transistor on/off and see if maybe one of its outputs is shorted.
