Hello guys, I've re-installed the CPU on my CFBL yesterday after replacing the connectors for cabinet switches. Now the game start (I hear the single "bong" sound and could play games) but the DMD shows no signs of life. I have reseated the connectors multiple times but with no luck..it worked flawlessly before..any idea on what to do? I share some pics, maybe I forgot something..

I have checked the fuses (f115 included) and they are good! Checked ribbon cables and reverted j211 to get all the red stripe on pin 1. Still the display stays black.. I have tested the voltages on the display and these are the readings:

Pin 1: 95,7
Pin 2: 96,3
Pin 4: 0
Pin 5: 0
Pin 6: 4,96
Pin 7: 12,5
Pin 8: 64,9

Any thought?? Thanks!!

UPDATE

I have tested the voltage directly on the board and the values on pin 1 and 2 change:

Pin 1: 119,9
Pin 2: 96,9
Pin 4: 0
Pin 5: 0
Pin 6: 4,96
Pin 7: 12,5
Pin 8: 63,5

Tested the suspected dmd display on my Dracula and it works flawlessly.
I have to suspect DMD board?

I would like to do more tests on BSD but after the dmd swap now I have problems on this one too D: it is continually blowing F114 on startup.. damn how unlucky I am!!!

Quoted from Pin_Guy:

I think you are very lucky as every game on my wishlist is in your collection.
Swapping the DMD should not have caused this as F114 is your 18V lamp power...perhaps a wire got pinched and is shorting to ground?

Thank you! You have a great collection too

Anyway according to pinwiki, this f114 issue could be related to br2, i have to take the board down and do some test..i will keep you informed!!
