Not on power up but on game up my top pop number locks on. The wire is off now any help would be great

Check switch 38. White/blue wire and green/black wire.

A photo might be helpful. You mentioned via PM the other bumpers have multiple white wires and the top bumper only has one.

What am I checking in the switch 38?..

Checking to see if it’s stuck closed. It’s the switch that tells the pop bumper to activate.

How do I do that. Thanks

Look at the switch. It will look something like this one.

I feel like we might not be on the same page with the repair help. Can you remove the glass? Raise the playfield? Use a multi-meter?

Reconnect Coil and remove switch inputs at upper left driverboard connector.
Turn power on start a game check if coil still comes on
Yes? then there is a short on the driverboard.

Ok I did just that. And yes it still locked on

I have the right readings coming from the switch
Also Replaced Q2 and the one above it more than once. Still locks on when game on. Not at power on

If it locks on only once you've started a game, it has something to do with the pop bumper switch as PINTEC is alluding to. Bad transistors will lock the coil on when you turn the game on, so your transistors should be ok. Continue following PINTEC's advice and you'll be up and flipping soon!

Add one of these to protect the board and coil.
Must have in my experience.

Locks on after starting up game with disconnected special switch input:
Check Logic Signal IC 6 Pin 1 must be high.

Are you saying it should be high? What should I be reading on this. Thanks

This is confirmed using a Logic probe High should be very close around 5V of using a volt meter.

1.1 volts

Looks like a fun, different enough version of Borg’s 3rd flipper Tron layout, which I thought was a must from John. I think another Borg fan would’ve gotten major flak from the community. I prefer the pro and premium art packages. The way the noses are drawn on the art packages is not my favorite animated style of the turtles; but overall it’s good with only the playfield a little underwhelming compared to Deadpool. Can’t wait to hear the sound package on Deadflip tonight. Hope it’s Jerry Thompson on sound, his sound effects are always stellar. Cowabunga to the TMNT fans, who should be psyched.
