Hey guys,

I'm new here so sorry if i'm in the wrong section but i followed an old thread here in the hopes u guys can shed some light on the machine i just obtained i power it up and the monitor humms so i assume the monitor is good but i get no picture or sound what confuses me is i got 2 boards with it a jamma board (which i cant get to fit) and some other style of board which seems modded to fit...if i post a few pics any chance u guys may be able to unclutter my head a bit lol

Cheers

Post pics. Is it a JVS, Irem, Namco or Konami board? It's possible it may have been modified to a JAMMA connection? Are you saying your JAMMA loom doesn't fit the board or you can't physically install the board in your cabinet?

is the link to my photos on flikr...

the only identfier i can find on the modded board says Falcon? tell me what u think after u have a gander

I'm no expert, plenty of other people here that would be better to help you. However I think your Double Dragon 3 won't fit because you have an different type of JAMMA connector in your cabinet?

No idea what's going on with that poker PCB. Looks like it has connections soldered to it to get it to work right, not sure quite what though.

cheers for having a look mate, from what i can deduce from looking and reading the orange wire is the 12v which is soldered to the board as for the other side i got no idea lol

This is what I had in mind for your Technos PCB.

Technos PCB? is that my poker one? that just turns it to the same jamma that double dragon is that dosent fit the plugs lol

[Pyongyang]

No, your Double Dragon PCB is made by Technos. Technos boards may have a different wiring/connector standard hence you can't connect it or it doesn't work.

Shows wat i know lol but like i said it looks the same as the connector on the board im trying to google different connector types but getting no where

wow, some of the modifications on these old cabs are crazy, i thought the weird jamma harness in my atari nova cab was weird until i seen this!

in the power supply picture, that looks like the old power supplys in the likes of an original pacman etc.. i could be wrong though. could it have been a dedicated cab to one of the pre jamma games that was modified to use jamma?

Looks like a newer power supply and jamma harness was added in? I could be way off, i dont know as much as some of the other lads.

on the monitor when you power it up, does the neck glow on it?

That is more or less what I'm thinking. Hopefully someone will see it and know the answer straight away.

i havent noticed any neck glow but i only powered it up in the day i should power it on now and see if it glows

[keithgeo]

In the pic with the board and the jamma connecter, it looks like the ground and +5v are running from the jamma connecter to that small bit of board. no idea why though haha

check out this image for a diagram of a jamma connecter.

yeh the "bulb" type thing should glow after a few seconds if its recieving power and working, if not then something is wrong. I have a cab with the same issue at the minute. its a pain when you are a beginner to figure these things out (im only getting into this myself.)

Dont touch anything on that by the way, im sure you know already but they can be dangerous. even when turned off, make sure you read up on the crts before you start messing with them.

if the monitor don't "glow" which means its dead i might convert it to a MAME machine
