[SOLVED] Hyper Olympic / Track and field PCB help!

[yocke]

Have an original Hyper Olympic Konami PCB that have been a big burden!
My conclusion is that it must be an power failure of some kind, but I don't really seem to find it!

I'm looking for suggestions!

The state right know is: http://youtu.be/jnjhqdMdb0o

Have tried different power supplies, the one just now is 5v.(7A), 12v (1A), -5 (1A)!

Suggestions?

Looks like bad roms. I'm thinking bad code roms as it is resetting.

Ian, thanx for fast reply!
Well I have thought in in that as well, any suggestion where to start? The board have allots of roms! Reburn all should take some time!

I saw in an Centuri manual that 12v should have 2A!! Anyone know if Centuri and Konami board is the same??

The boards are the same for sure. It would't hurt to find a better power supply and see if that helps. That seems like a pretty small switcher.

If the power ends up still not helping, you should maybe start serially testing each eprom. If you have a burner or know of someone with one you can just remove one rom at a time and do a rom dump, compare with romident and see if you have any bad ones.

Hmmm,

No luck at all,,, but did find a chip with a broken leg..
Takes time to dump, and check each of all eproms,,,!!
