How dead is dead?

What have you done so far to diagnose the board?

If the battery is good , you may have a bad connection between the "A" and "B" boards...


*edit*

please post some pics of what the board is doing

In addition, the battery may have been replaced after the board had committed suicide.  (By an operator who thought it would still work if they put a good battery in there).  In that case, the board looks like it's fine and the battery has juice, but the board itself is toast.

What kind of answer is that.  That's not going to help him is it.

The answer he seeks is one that cures his problem. First of all we need to know what output he's getting at bootup. Is it completely dead with nothing on screen or does he get the start of a boot sequence with a rom check that then fails.

If it's the second of those then it is fixable for most CPS2 boards. There are replacement boot roms that have the suicide code burnt in and that will never die. You just make a few wiring changes, buy the replacement boot roms and pop them in. You can recover a board that has died like this.

If on the other hand, it's the first of those then the battery and code may be fine, but the board may have another fault. We need to know exactly what's happening to be able to answer.

Best Regards,
Julian (Fozzy The Bear)

Actually, if the battery is dead and the encryption is thusly lost, you won't even get that boot sequence.  You'll just get a bunch of garbage on your screen.

That kind of comes right back to what Fozzy is saying. What does the OP get on boot? Is it an actual boot sequence or does s/he get garbage. It's a little silly to be arguing over a solution given the information the OP gave us....

dead cps2 board but the batteries fine...

That gives us a total amount of jack ---Cleveland steamer--- to work with. I too have a dead CPS2. My A and B boards don't need to be taken apart for a visual inspection to show some kind of starting point to the problem. Should I offer the solution that would repair my CPS2 board to the OP based on the information he gave us?

Seems kind of silly now doesn't it?  ;) ;D
