ok, I EFFED up a guy's centipede, need some help

Let this be a lesson to not try to fix other people's games.

Fixed

If it were a harness (edge connector) issue you should be able to wiggle the connector and "fix" it temporarily. I kind of doubt it's strictly a connector issue personally. You didn't mention swapping the boards so there's no good reason that the edge connector should have decided to fail at that moment. I would still at least take a look at it and swap the boards to determine if it's a board problem.

I went to try to change a monitor on a guys non working centipede.
He happened to have a working centipede there as well, so that was cool so I
could trouble shoot a bit.

Anyway, as I am testing the non working one in different ways with the working one I got into a situation where the working one, started showing just a white or yellow screen.
It played blind, but no video recognition.

It happened shortly after I discharged the monitor in question(working game) not sure if it's relevant.
I had an extra monitor and hooked up the video wires and power to it, and got the same yellow screen.
Then I got the non-working centipede (which was playing blind) hooked up to the extra monitor i brought and it came up just fine.

So now I have a non working centipede that plays blind and cannot figure out the issue with the monitor. I thought maybe it was a sync issue.
I am hoping someone knows what I should do next.
The guy lives 1 1/2 hours away and I need to go back there next week and figure this out.

Swap the boards and see what happens. I kind of skimmed the thread but it sounds to me like you have enough working parts to follow through with the trial and error trouble shooting to figure out what blew up, if anything. I probably would have taken the boards to test at home.

Is this guy a friend of yours or something? Is he paying you for the repairs? 1.5 hours seems like a long drive unless this guy is a good friend.

EDIT: I have working Centipede boards to sell. $100 shipped. If that's too high check ebay.

Just saw this thread. I bet you toasted A9 on the main board when you discharged the monitor.

That's cool.

Price reflected my desire to pull a board out of storage and test it

for anyone who is interested, the guy went ahead and tested the other board in
the originally fully working machine and said it worked.

So I fried the board, lol.

lesson learned

thanks for the feedback

Kinda figured..... but it may just be one chip.
It was mentioned earlier as maybe A9 I believe.
