Well your right. It's gotta be the adapter or a board issue. If you don't have jamma test right you may have to send the board out for repair.
 
I have a fully working 4 board stack if your interested. I also have the same adapter board and I know it's all working.

DM if interested.
 
Yea, this sounds like an issue isolated to just the board stack. Frustrating that you just saw it working once. But things can break at even given moment. Doesn't necessarily matter that it was just working 5 minutes ago.

Might as well check to see if you are getting 5V on the board. Not going to tell you much but can't hurt to know if you are at least getting 5V at the board.

Also doesn't hurt to reseat socketed chips and check for leg corrosion.

I'm going to get rid of it it's going to cost me an arm and a leg to send out to fix and I don't have the tools to fix it myself.

I had another Tkg3 board tested good, do the SAME THING. Why??? Is the mikes arcade pinout different than the tkg4? Why does tkg4 work and the other not???? TWO (tested good I might add) Tkg3 boards non working. I was frustrated now I'm a little pissed off. I'm 100% sure I wired my harnesses correctly.

I tested this in my TWO Nintendo cabs, rebuilt with mikes arcade harnesses. either I'm the dumbest person alive or someone is wrong with the adapter/harness combo.
 
GOT IT WORKING! Added some tin to the edge connector View attachment 797967
This was the STUPIDEST issue ever. I figured it out by licking the connector (stupid I know but hey, it worked on my Nintendo DS years ago…) and i got some red color… I told Mike from mikes arcade and we called and thought to tin the connectors… and voila!

Sounds like the pins on the harness need replacing since they're no longer tight.
