Sega-Naomi

I have error 22 problems on the motherboard.It tells me that it is not picking up the dimm pcb.I have 3 dimms and it does the same.But i also have tried it on my other 2 naomis.Comes up with the same error.

What the hell is going on.

I have spare i/o pcbs motherboards and dimms and gd roms players but i am getting this error,even when i swap parts.Voltage is set at 5.2 volts.

I was playing Trizeal last night with no problems.

All the problems started when i swap games.

I just bought vitrua tennis 2 and i thought i test it and play it.I swaped discs and security chip and thats when all the trouble started.



Please Help.

Try using another usb cable. I had an instance where I had the GD system connected and lost usb connection. It seems that the Naomi's error priority is a bit odd... :smt017

Anyways, changing the usb cable stopped the Error 22 when all else failed.

I have done that,but it didnt help.It boots up sometimes.I suspect that the dimm rams are faulty.

Any one else confirm of ever having faulty ram?

If you can go into service mode, you can run the RAM test and find out.

It does not even resister the dimm pcb.I have tried 2 dimms with no luck.

Any other ideas,or am i looking at getting new dimm pcbs?
