Hi all,

Got myself a pretty beat Firepower and been busy shotguning the boards since.

Now everything works perfectly except for the Match that displays 02 constantly.

Any idea on how to troubleshoot that?

What has been done so far:

- changed all headers (including the 40pins)
- swapped all IDC connectors to trifurcons
- replaced all harnesses connectors+housings
- replaced ALL caps on all boards
- Installed mosfets instead of TIP/ceramic resistors on the driver board
- reflowed all suspect joints
- installed Inkochnito bridge board
- installed barakandl NVram + Special Solenoid Saver board
- Replaced the 100V diodes by 91V on the Power board + some others following vid1900 bulletproofing guide

Solenoids, lamps, sounds, speech, are all working flawlessly.
Player 1-2-3-4 displays are all working flawlessly.
Everything looks good on the Master Display board.

Match window = Strobe 15 and 16,
so I've followed the wires from the display up to IC6 on the MPU but no signs of broken wires/trace. I have continuity.

Two other things thing I can report:
- in the Credit window, Strobe 8, there is a little flickering when on 1 (but not with the others numbers)
- I still have original ROMs sockets. So maybe Scanbe. Although wiggling the chips in game doesn't cause any issue.

Good question, will recheck tonight

It is set to 01

Ok it's official: I am completely dumb!! The left windows of the Master display actually shows... the Credits.

So I guess I simply have 2 credits here. The game was set to Free Play so I thought this was supposed to remain at 0 but I was forgetting about the credits earned in game... What a brain fart.

Will recheck everything tonight.

(still got to figure out that flickering number 1 in the Ball in Play window though)

Roger that. Will change it and see.

Thanks a lot PINTEC !

Ok everything works perfectly except for that very slight flickering on the Ones of both Credit and Ball-in-Play/Match windows. No big deal.

thanks again @pintec
