Raiden Fighters Jet PCB problem

Kenchan · Post by **Kenchan** » Sun Aug 24, 2008 5:37 pm

I found an almost new Raiden Fighters Jet board that's busted, guy said he bought it new and had it for a week and the board just died. He's pretty knowledgable about arcade stuff, couldn't figure out what was wrong. I thought it strange that it died so fast, I was wondering if this is a common problem and if/how it can be fixed.

As for the problem, either nothing comes up, or a little bit of garbled graphics, usually nothing. Any help would be appreciated

Do you have another SP1 mobo lying around to check and see if it is the RFJ cart that is acting up or could it be your SP1 mobo is Fubar'd?

It does help to have more than one SP1 mobo to make that finding conclusive. ^_~

And have you tried increasing the 5v line on your Egret II to see if it clears up the problem? If not, try flexing the mobo and see if that helps.

Do you know what country region mobo and cart the RFJ combo is?

And what version number is your SP1 mobo as well?

Well it's not my board, but I suppose it's worth the trouble of picking it up. I'll try that, see how it goes. I can't say what region it is since the guy who has it doesn't buy exclusive US. I'd guess it's JP, can you tell from the box?

I know those carts and boards are region specific- maybe he lied about it working (just thought I'd throw that out

)

Seems shady.

Bought it new? So he paid a few grand for it.

So lets say he bought it new, it died a week later, supposedly he said "oh shit this sucks, oh well" and put it away? What about sending it in for warranty repair since it was a week old purchase?

Shady.

I don't remember it being a cart system :/ maybe it's a different game I'm thinking of? I'm pretty sure it was Raiden Fighters Jet tho.

That said, his office is about 5 miles from me and I tested the board myself. I'd be paying 10 dollars for it. Apparently he couldn't get it fixed under warranty, so I don't know the whole story. I'll probably drop by there tomorrow or Tuesday (picking up Last Resort) and fool with it, maybe bring it home. I know at least it was new, it was in the original box and he said he still has the marquee and stuff sitting around somewhere in the warehouse. We'll see :O

there are multiple versions of RFJ, some of which have 'carts' (although they sorta don't look like carts, and people rarely swap them) and some are 'single board' versions.

The carts are large-ish black things like this: http://page5.auctions.yahoo.co.jp/jp/auction/e64836479

Yeah I double-checked this on MAME, it is indeed single board. If it's a data error, I should be able to rewrite the ROMs probably? After looking at it again, I really can't see anything wrong either, so it's most likely a chip as opposed to something on the board. Thanks for the help guys, I guess I'll fool around a bit with voltage adjustments, if all else fails it was only $10 anyway.

Ten bucks = 40 quarters...ain't that much money lost if the RFJ PCB doesn't pan out, son. ^_~

A high-res PCB scan would be helpful

Will do, although like I said there doesn't appear to be anything visibly wrong with the board.

Might be one of the "2000" boards, show us a picture and we will help.

Yeah yeah slow, finally got around to this.

Any help would be great, otherwise I'm just going to try swapping the simpler ROMs then try the soldered ones if that doesn't work.

EDIT: bigger picture here. Appears to be a "2200".

Swapping ROMs? I would try re-seating the socketed EPROMs first. You won't be swapping the MASK ROMs with anything.

Oh man I have always wanted a single-PCB RFJ board. I'll give this high-res photo a look-over when I have some more time.(although if there is a cold solder joint it will be near impossible to spot, i'll just be looking for any physical damage).

Trying re-socketing. Reminds me, when I throw it in, it makes a bad sound, don't know if it's the speakers or the monitor, but it's almost like a fan starting up with a piece of paper stuck in it.

EDIT: Speakers. Turning the potentiometer makes it go down. Amp has had work on it in the past.

Nice picture, however this is not a 2000 version. The 2000 version looks like this:

Notice the copyright 2000 at the bottom of the PCB.

Your PCB is the proper single PCB version. The ROM is most likely
Raiden Fighters Jet (US, Single Board).

Your PCB has the original sound chip, an EEPROM instead of battery backed RAM but no stereo. Apart from that it's the same.

Do you have any other SPI boards, the RF series outputs a strange frequency which confuses a lot of monitors.

If you power it up do you get a sound if you coin up or press service ?

sw1 turns the screen black and goes back to the normal garbage+drone. Reset switch? It also increments the coin meter. Test, Service, and adding a credit don't do anything, same with the buttons.
