Hey all,

I have a Stern "Big Game" that I am trying to fix up and I'm running into a problem.
When powered on the MPU gives me 2 and then 4 flashes indicating a U11 problem as directed by the Bally Stern Wiki's Flash sequence guide:

Now I went and got a new U11 and replaced it and still the same 4 flashes with the LED NOT staying on.
Daaaaamn. I looked over the board and it looks really good! Very healthy looking. What should I do? I have a new U11 "seat" that I can replace on the board but that's a last resort. Anything else I can look for before I enter soldering hell?

Thanks!
Ryan
