What was the bad connection IC for futrure reference?
That looks like a bad connection with your carts CHA or again I would have to state ZMC2 or B1 on the board.
BB
Looks similar to the problem with A3 - see here:- https://wiki.neogeodev.org/index.php?title=Graphic_glitches
.... Aaaaaaand we got a fix
Not sure what was the final golden touch - but I resoldered everything once again with high temperature and soaking in flux do make sure there are no micro solder bridges that can't be seen with the loupe and went over the whole board.. and it seems to work.
Thanks again guys - I am glad to be part of this great community
Great job! Another notch in your repair belt. Now if only some of your good luck would rub off on me.
I didn't even start my "bad board" yet - so it's no comparison really. The board that I repaired now was showing stuff and that's much easier than watchdog clicking or freezing garbage.
Maybe my MV-1FZ concept acrylic case will cheer you up ?
Is there somewhere that I can buy those cut acryllic pieces? They look cool!
EDIT: Great job btw =D
Phenomenal!
Wow, very cool! Would love to buy a that black one at some point!!! Maybe a clear too! Any idea on cost and shipping to the UK?
Have a good day
Thanks for that pdf! Saved me some time recently!!
have you tried the Unibios? I have a bad 1FZ, with the same issues (clicking due to faulty watchdog timer). With the unibios, it posts an error on boot, but after that works fine (shrug).
