Hi,

I have a problem with my Naomi1. He dont detect my game (error 1). When i make a RAM TEST in the TEST MENU, the IC29 appear to be BAD.

Have you some idea to resolve my problem?

Thanks!

My friend Ken Westerfield, will be your friend too..

IC29 sounds like a Korean Memory IC, they normally get shafted.

Man, that sucks. IC29 is a section of RAM on the Naomi mobo. Ken is great! He's fast, efficient and has good prices. I'd love to learn what he knows! :smt110

Ken answer:

"Don't change IC29. It's not bad. Your back up RAM cap leaked and corroded traces and eyelets open. If you don't have a microscope, it will be nearly impossible to repair. I can repair it for $75 + shipping provided this is all thats wrong. Normall this is all thats wrong"

And it's right i see some strange things on the IC29.

Thank you very much!

Naomi 1's are NOT worth fixing IMO, cheaper to buy a replacement from eBay.

Second that. Especially if it's $75 + shipping (no offense, aslasha, commendable nonetheless that you're able to)

I have a motherboard that is randomly freezing I went into the test menu and it came up with IC29 bad before freezing again argh. After reading this thread I checked the cap and it is the exact same problem.

I have removed the leaky cap and can see that the trace that went to the gnd pin of the cap is broken. I've just bought a replacement cap from maplin (N99CN - ?1.45) which I will stick in there and add a wire for the gnd pin, I'll let you all know how I get on and if it fixes the problem.
