Hi all,

First of all a big thanks to all the resources I've already found on the forums here while fixing up our Whitewater. Been very helpful.

I'm still struggling to get our playfield flashers up and running. I will try to list below the observations we've made so far.

- The whirlpool enter flasher (#23) stays on as soon as the game is powered on. Had to remove the bulb to stop.
- Removing CPU ribbon from power driver, whirlpool stays on (not a CPU issue)
- All flashers have 20v - 21v when testing their prongs while grounding the DMM.
- All flashers fire when manually grounding their TIP102 chips via the braid & tab
- All TIP102 (including #23's Q28) seem to test fine (not stuck open) by doing a buzz test between legs
- Pre drivers seem ok based on my amateur DMM tests while machine is on

I am not very experienced when it comes to PCBs, but I can follow instructions well and know to follow a table / matrix. If soneone is able to help us continue to diagnose this, it would be realllllly appreciated.

Now the wildcard, which may be related. Our power driver board has a repair hack on the IC's - I have no idea what it is for, perhaps shorted trace behind the chip? I was told these are for the Solenoids, but I also know flashers run on solenoid so am nervous perhaps the issues all come from this repair. I have attached pictures which hopefully show what's going on

I don't have a logic probe, but happy to use the DMM if instructed to test whatever may need testing.

Really appreciate any help here

After removing the power driver board it was clear from the connections on the back the IC had been replaced at one point along with two of the TIP102 components.

A quick touch with a hot solder iron to the tip102s and a little clean up of the IC legs and now all is working.

The whirlpool flashlamp is still stuck on, but I suspect that's a more regular issue among its components.

Very happy!
