Hi all (again, in my second thread),
I have 2 MVS MV1FZ boards which dont work.
The first board worked fine 3 month ago...but a day show Color Ram Bank0 error. I dont want repair this MVS.
The second MVS, on boot shows garbage screen. I have recorded a video, you can watch it here:

I am using parts of the first MVS board to repair the second.
The second MVS dont show nothing, one time with the neo diagnostics Bios I saw "BRAM Dead".
I have replaced the chips marked in the pic, and now i have garbage screen, Neo Diag bios doesnt show nothing, original bios the same, and the same with unibios.
I have logic probe...but I dont know well how it works...
I hope you can help me.
