Have a tspp on location. Thought my dmd was gassing out. Went to turn it on and boom. Looks like new. Very strong. So i wiggled some wires the power idc was a little loose. Reset that. Thought i had it covered, played a few other pins. 15 minutes later its back to whats show in the image. So i went back and wiggled more wires. Couldnt get it to change. Other than turning it off and then back on. When its first turned on its fine. Then after a while it looks almost unreadable.

What voltages should i be looking for? I have a replacement dmd. But i dont think thats the issue.

Ideas?

The connector/wire that you wiggled is it in good shape no signs of burns?power off Try reseating all the ribbon connectors from board to board and see if makes any changes

No signs of burn or that it got hot. We re-seated a bunch but will re seat them all again.

Fixed it. Cracked solder joints on the display power supply board. Re flowed both connectors. Works like a champ now. Kind of suprised that a game this new has cracked solder joints. Glad it was a pretty simple fix.

Hope this helps someone down the road

Hey Nick,
I'm over there playing all the time. I was gonna suggest some cold solder joints to you if I ever bumped into you. You could bump the backboard and get the display to work again. Dead giveaway. Glad you got it fixed so I don't have to Fonzie it to see my score at the tournament tonight!
