Help me learn a $40 lesson

[Haloman800]

I was testing a 60 in 1 board along with wiring arcade buttons (I'm building an arcade from scratch, never done this).

The board powered up, controls worked, all was well. However P1 left wasn't working so I kept turning on the board, testing it, unplugging it, checking the wires, and repeating

I just plugged it back in and I heard a "pop" and now the board won't work at all. What did I do wrong? Any chance the board isn't fried?

You didn't plug it in while the power was live/on, did you? These aren't hot swappable like that.

[ark_ader]

Sure.  Send me $40, then consider it a lesson learned.

While we are talking about lessons, how about rule #5.

This 60 in one board is illegal, and probably dead which is a saving grace, so which law said that 60 in one boards are legal?  It's not year 2090.

If you fry an original arcade main board, help should be given but an illegal board should be ignored.  Ethics.

[Mike A]

Yeah. Because dowloading the ROMs is  more ethical than buying the 60-1 boards.
Exactly how tall is your high horse?

I thought the same.

Can you take a picture of the component that let go? Might give some clue as to what happened.

To be honest depending on how much spare time you have you might be better off just going over your harness very close, checking the power supply voltages and buying another board.

Its unethical to to pounce on 1 guy for buying a freely available product when he asks for help.

Aint like most of us are any better really....

OP regarding your problem nobody will really be able to tell you what happened based on the info you gave.

The chances are something has shorted out which could of happened in any number of ways from damaged wires in a loom, a error on your part connecting something wrong, could even be you accidentally shorted 2 pins by resting them on a screw or something daft like that.
Could just be a faulty component.

Which part actually went pop?
Has one of the capacitors gone pop?

Yep, he fried the board. The same thing would probably happen to any arcade board if you plug and unplug it like that while the power is live. I stupidly did the same thing to a force feedback board in a racer that I own.

If hes been unplugging the loom instead of the power very possibly lol

[big10p]

Maybe you plugged the edge connector in upside-down? That'd fry it.

Yeah. Because dowloading the ROMs is  more ethical than buying the 60-1 boards.

[Malenko]

Its not against the rules to discuss the 60 in 1 or fixing them, we just cant discuss where to get them (or link to store fronts).

That being said, the board probably isnt worth trouble shooting just get a replacement.  Is your JAMMA loom keyed? IE, is there a plastic piece separating the power side of the jamma from the rest?
If its not, get one that is. Already stated, but worth repeating is, dont try to hot swap it. Power down before connecting or disconnecting the edge connector.

I'd still like to see pix of the damage

[paigeoliver]

Examine all your caps carefully, I overvolted one of those boards once and popped a cap and it was fine after I replaced the cap. If that isn't it then it isn't worth troubleshooting further.

[pbj]

Except that store fronts that sell those boards also have banner advertisements on this very website.

 

Anyway, he's clearly getting power from the molex connector.  Probably flipped the JAMMA harness, pressed some buttons, and shorted out the power supply.

[Nephasth]

$40? I remember when these things were north of $100...

The traditional long term arcade vendors tended to charge a lot more for them than the guys who work out of their house. They have been hovering around $50 now for many years.

Last one I bought was $60 plus shipping about 5 years ago.

If you don't need it in a hurry you can get them from China for around $35 including the shipping

Well it's way up there.  60 in one boards do not show copyright information in the games, and they run old mame software.  I can download legal roms that have been donated to the community.  Remember Star Roms?  There are alternatives.

Clearly you guys are riding pigmy ponies.

[Mike A]

Those are pygmy ponies. At least spell it correctly if you are going to insult my integrity. I hope every ROM you have ever downloaded is 100 percent legal if you are willing to be a colossal --cream-filled twinkie-- over the issue.

[behrmr]

If you plugged it in and heard a pop you probably blew an SMD chip.  Look for one that is damaged.  You most likely over powered it or plugged it in backwards which is easy to do if your harness connector is not keyed.  Do you have power on your JAMMA harness or just on the connector on the side?  If you fed it more than 5.1-5.2v you probably blew it. 

And I have one of these on my test bench and I plug it in and pull it out while still powered on all of the time and have yet to damaged it. Doesn't mean it won't but doubt that's what did it.

[gdonovan]

One would think that a newcomer would be encouraged in these forums not berated.

WTF dude, you wake up with a stick up your bum this morning?

[Malenko]

Of the STAR ROMS and/or publicly released ROMs, none are available on the 60 in 1 board.
No one said that its not possible to use MAME without infringing on any copyrights, so I don't understand what  point you were trying to make.

[pbj]

Wasn't Star Roms shut down as a load of BS anyway?

[Malenko]

Nah they got the rights to resell, everything was on the up and up. But either sales weren't good or fees went up and their catalog dwindled down to like 25 ROMs then they shut down.
They havent been around for like 12 years but facts never slowed Ark down before, why should they now?

I remember buying pretty much everything they had. However how in the world do I prove that now?

For your sake, I hope you find some receipts or you done goofed.  The ROM Police have been merciless in their backtracing and consequences will never be the same.

[ark_ader]

Damn straight.  I'm going get on that high horse, and ride off into the sunset.  I remember reading how the 60 in one boards pissed off the mamedevs which can knock on rule 9.

The plot thickens....

[Haloman800]

Wow, it's nice to see my thread created such a vibrant discussion, lol.

Sorry for the delayed response. To answer questions:
1. The harness was plugged in the correct way
2. I only powered the board with molex (no power was hooked to the harness
3. I did not plug/unplug the harness while power was on
4. I had it plugged in to a power squid outlet, which was plugged into a normal wall outlet.

Here is a video of the board, if you want a closeup of any part, let me know

Sorry your thread got derailed. I just got irritated that you came here for help and the ROM policeman started spewing rule numbers and moral judgement at you. Notice he never answered whether her owned the rights to every ROM he has ever downloaded. Most of the people her are helpful. I will get out of the way and let the people who know their stuff try to help you out.

Thank you, I appreciate your help. If I can't fix this board, I just want to know what I did wrong so I don't break any more in the future.

Look at the board closely and look for any blown caps. They are the black cylindrical things with a cross on the top.
If they are blown the tops usually open up a little and they sometimes also diss-form slightly.

The other thing you can look at is any discolouration of the chips that may give you clues.

Use your nose (literally) and you may be able to smell out the dodgy component.

As for causes I listed some possibilities above but there are loads!

[Malenko]

another example where 1 hi res pic would have been better than a video

I didnt see any blown spots on the board so I really dont know what to say on what "popped"   Its entirely possible that you didnt do anything wrong and the board died.  They are mass produced and I dont think there is a QA team

[Mike A]

Sorry if I missed this, but did you try powering the board through the JAMMA connector instead of the molex plug? I don't know if that makes any difference with these boards.

[big10p]

Since you say the board does nothing now, I'd also check your input voltage. Maybe the PSU popped, and not the board...

[Malenko]

That is actually a brilliant idea. When I did use a 60 in 1 I had it wired to a regular switching power supply.

Also how I power mine.

Yes, check the power supply, and check the solder joints on the pins on the board where it plugs in.

Well unlike you I have a life, but to answer your rom question, I do have only 5 rom's in mame that I use as I have the physical board or disc from an approved licensed body.

I turn off auto correct on my phone, but when I get an update it activates again. So are still on a pigmy pony?

[pbj]

You don't own ---steaming pile of meadow muffin--- and if you have such a moral issue with being around ROM pirates, there's a simple solution:

Wow I guess I hit a nerve.  I think you need a time out.  If you cannot think objectively, that is your problem.  60 in one are not legal, find something that contradicts.
