Damn too late. Just curious is this fighting Bujutsu or fighting wushu 2nd! the updated version with extra characters and balance tweaks and such?
 
Darn. Well hopefully it gets some tlc and the parts it needs to work again. Hopefully it gets a good home. I hear the Konami cobra pcb is very complex and delicate.
 
I'm the one that picked it up and I fully intend to get it as close to working as I possibly can and documenting the fixes if I find them. No promises on timeline though.

So far what I've discovered is that the thermal compound on the video board has completely crumbled to dust and the spring tensioners on the heats syncs weren't even making good contact (all head syncs were essentially "lose" and could be moved by hand). So it's likely those chips all cooked themselves to death once the thermal compound failed.
 
I see. Are you plan on putting it in a cabinet? I’ve seen adverts that place it in a Konami Windy II cabinet. Much different than the one the original was with the two seats and huge screen.

yeah I really haven't touched this since my initial investigation when I got it in.
basically the "leaf springs" that hold down all of the black heatsyncs with the temp monitors had lost all of their tension and the thermal compound had turned to dust on all of them too so none of them were making pressure against the chips and were just flopping around.

I did some searching for some replacement springs but couldn't find anything.

honestly if the temp monitors are there to shut down on overheat then they really f-ed up the design because if the springs or the thermal paste fail then the CPUs will cook themselves without the temp monitors even realizing it. could be why all these things are dead.

Yeah it’s basically a bunch of pcbs stacked together correct even if you did get it working which I’m sure you’re more than capable there’s the issue of getting an E1 error… right?
 
I did some ai research and feedback and it mentioned something about thermal paste and non conductive shims and standoffs. I think

  • nylon bolts, nuts, and non-conductive washers. This allows them to manually dial in the exact amount of "clamp" pressure needed to keep the heatsink tight against the chip.
  • Modern Thermal Pads: Instead of liquid paste, they might use high-quality thermal pads. These are "squishy" and can bridge small gaps if the board has warped slightly over time, ensuring 100% contact.
