I just recieved a japanese cart system today and it wont seem to work. No matter what game i put in, whenever i turn on the system all i get is scrambled pictures without sound. I cleaned the system with compressed air and it stil didnt work. Anyone know what could be wrong?

All I think of trying is to insert the game fully then back it out a hair, then turn the system on. However it sounds like your system may be toast if this doesn't work. I know there are a few members on this board that may be willing to repair it if possible.

Thanks for the reply samurai, however that didnt work either. Anyone know how much it would cost to repair it?

You really need to give more information.

What cable are you using? Is it a standard RF (goes in aerial socket) one?

If so, it has a weird tuning - retune a spare channel with your Neo connected and turned on until you get a picture.

If you have no joy, plug headphones in the front and see if you get sound.

Also are you *sure* its a Jap unit and not a PAL one (you're in the states, right?)?

Its definately a japanese unit. Im using AV cables, and ive tried two sets. Yes im in the states. Also the slots are very tight, would this have anything to do with it.

Hey,

Do you only have one game? FF2? Maybe it is the game, because I have a 230XXX NEO GEO and FF2 does what you described--scrambled picture w/ no sounds.

Hmmm...what are the 5 carts. I will try them too to double check.

NeoMark, you didn't say - have you tried headphones in the front, and what result do you get from doing that?

I'd suggest cleaning the carts first with contact cleaner (must be NON lubricating type) and q-tips as you'd call them.

Check the cart port too for obvious signs of damage (e.g. bent or missing pins), or bad dirt/corrosion.

I had that problem with mine that I bought from a person, but drove over to snk usa about 2 years ago and they replaced the system for $75!!! They said there were bugs in it and they scrambled the chips and stuff. (Interesting story behind this whole visit, I will get to it later) Well I paid $90 for the cart system and 5 games when i bought it off a person, you get what you paid for hehe

It has nothing to do with the carts. I have another system and all the carts work perfectly. All the cables work fine too. The only thing i can think of is that i might need a reverse voltage converter, does anyone know if one of these is required to run a japanese neo.

it doesn't matter what the input voltage to the PS is, it only matters what the output voltage to the neogeo from the PS is.
so a voltage converter wouldn't have any influence.

That isn't true. The AC adapter is designed to convert voltage/AC X to voltage/DC Y. If you change the input parameters, you are changing the output paramaters too. Most people feel that the US and Japanese standards are close enough that it doesn't matter much, though.

I use 5 US and jap systems with european power supplies (which are ENTIRELY different, 220 V/50 Hz as opposed to 110 V/60 Hz) and they work perfectly, as well as one US PS via a voltage converter, the output is identical in all and there are no problems.

NeoMark,

Could you post a pic of the AC adapter. I switched some of my ac adpters by accident once and I thought my neo geo was broken. There are three different ac adapters for the Japanese neo geo and each is designed to work with one (maybe two) versions. If the seller has many neo geos in stock, then perhaps he/she got the ac powers switched and you are experiencing the result of that.

OK, this is kinda getting off the topic... but to continue what seems to have been started....

NeoMark, does the transformer have an output voltage and current on it? If not, do you have a multimeter you can test these on?

However, I rather think the problem may lie elsewhere.

I wasn't saying that you had dirty cartridges, the point was more to check the connectors in the machine for any wear or broken contacts.

If you wanna e-mail me, my address is @hotmail.com

I guess this was probobly the first thing you did, but have you tried cleaning the cart slot? A N64 cart slot cleaning kit might do it? It does sound like a chip problem though. But its worth a try. <IMG SRC="smilies/frown.gif" border="0">

My neo uses propow3 ac adapter.
These are the output parameters for this adapter: DC 11V 700mA

I do not understand what you are saying. Are you located in Europe? I can't understand your point. If you are in Europe, you should be using European AC adapters.

Brent, read from the beginning of the thread. Arakon didn't start it, just stated that he has JAP machines which he uses in europe with european PSUs.

NeoMark,

I'll take a pic of mine and email it to you. Let me know if it is the same as as yours.
