Sega-Naomi

Hello,



I present my self I am a sega fan and I have a couple of cabinets.



I have a problem with one 1 my 2 chihiro system.



I can get it to boot, I always have a black screen, and on the boot sreen just before my first black screen, I had on the screen an error 02 (mainbd or motherbd).



As my other chihiro system boot correcty on the same cabinet it is not a voltage problem.



Does someone has an idea to what to do: maybe some thing wrong with the bios.



Thx

02 is main board malfunctionning. Nothing you can do without a solid technical knowledge. Send it to Craig or Ken Westerfield maybe ?

arrrrrrrrrr,core board failure

you could try cleaning and reseating all the boards but it sounds fatal to me

Can you get it to come up to the test menu? If so, run the memory tests to see if you have bad RAM.



If not, you'll need to send it off for repair.

Error 02 = Baseboard fault



The board in question is the smaller board which interfaces with the XBOX Arcade board.



Error 02 can be caused by a loose wire or connection, strip it down and re-seat everything.



Also black screen, make sure your fan is spinning on the CPU, they have a tendancy to die.

Thx to all,



after check fans are ok.



I will reseat board and see if it is better.



Thx for your support.

After re-seating everything, I always have a black screen.



As the chihiro mainbd is an xbox motherbd with xbox video and audio output, I tried to to connect chihiro mainbd video and audio output directly to my TV with xbox video cable (instead of to the smaller chihiro bd). And I got it the chihiro boot screen my gdrom start to load, and it came to caution 51 screen (wrong horiz or vertical frequency).

So something is wrong with the smaller bd connected to the mainbd.







Does someone has an idea to solve this matter.



What I can do now, i think that I can get in the menu but to check what?



Kind regards

Odd, you using an AVIP cable??



It goes from the XBOX AV connector into the Baseboard.



The frequency is controlled by the dips, but that is related to the base board.



Sounds to me like you have a faulty base board.

Do you think is it possible to repair it or that it is better to replace the base bd.



Or try to run the game without pass video and audio signal through the base bd and solve the caution 51 problem (on my point of view the problem is that the system detect that the screen is a 15khz monitor (my tv) and not a 31khz monitor as naomi cabinet monitor and do not start the game).



And as I said there is no native mode on chihiro system, this is the problem.

I doubt its too hard to repair, i'd guess more expensive to replace.
