MPU Board Repair (7 Flashes) Stern M200
« on: October 16, 2011, 02:45:22 PM »


I bought the MPU for Stern M200 board from ddstoys.

It needed some work on the board, mainly corrosion issues.

I have cleaned out the corrosion on the MPU board, also cleaned up the acid, replaced all IC sockets, three IC and some tracks.

Have installed MPU repair kit from G.P.Electronics.

Thanks to ddstoys for the MPU board.


Testing was done on Bally MPU board tester.
