i went to the store to buy bulbs for the coin mech i come back my retarded sister popped open the coin mech flipping the switch.
then i got home the damn thing is off with no power going to the monitor or anywhere else on the machine.
my machine is a street fighter 2 game.
i called the guy up who i bought it from he said it might be an airlock protection or someBS.
i only had this machine 3 days!
PLEASE SOMEONE HELP ME!!!!!!!!!!!
has this happened to anyone else yet??

Do you have a multimeter?

what the world is a multimeter??

Some game cabinets have a white pushbutton switch that the back door, coin door, or control panel slide out drawer pushes when the game is closed up properly. This is called an "Interlock" switch or "Safety" switch. It's purpose is to kill the power to the machine when the back door is open, the coin door is open, or the control panel slide out drawer is open. Frequently the screws holding the switch mounting bracket loosen allowing the switch to slide back just enough that the power is killed to the machine. Sometimes the bracket bends a little causing the same problem.
Some people have removed these switches and bypassed them. For safety's sake DON'T bypass these switches (especially if you have small children in your house!). They were put there for a reason.

so wheres the screw or switch at on my machine AND how do i disable this protection crap??

The switch would look something like the one in this link.

As for where it is located on your machine, there is no way for any of us to know exactly where it is. But it would be near a coin door or some other door on the cabinet like Ken said.

hmmm ... learn something new everyday ... "Interlock" switch you say (wondered what that was for when browsing the Happs site) ... haven't had the pleasure to come across one of those yet ;D

Open the back door of the game and there should be a white switch near the door. The door pushes the stem of this switch when the door is closed which in turn turns the power on. Most games also have a regular power off-on toggle switch at the upper right side of the cabinet above the lighted marquee (JAMMA standard).
As for disabling a critical safety feature I never do that. In fact when I work on someone's games and I find that switch disabled I hook it back up and I charge them for doing it, too.

ok i found the on off switch BUT i turned it around and to my surprise there isnt a back door!!
please help is there anything else i can try to see whats causing this??
i havent got a voltmeter yet but i will later on today just curious if it aint getting no power when i get the voltmeter does it mean its ALL dead??
-
If this is a dedicated cabinet then unlatch the control panel and tip it down. Then you should see a couple more latches that allow the entire drawer to slide out. This is where an interlock switch may be mounted. Shine a flashlight in there and look around. It's possible your main line fuse may have blown (it should be in a fuseholder near the power supply).
Can you post a picture of the cabinet?
-

No...
Don't worry too much...
Most likely this is just a small problem & fix.
If you can post pics of the back & front of your cabinet it would help greatly to know what we are dealing with.
If you don't have a digital camera, see if you can borrow a friend's (or this could be a good excuse to get one...).
& there will be some sort of back door to this thing... Usually there is a lock of some sort near the top (still on the back panel though) and when it is released the back panel comes off completely... (tilts back & lifts off).
Don't panic & just try to work with us & we might get this figured out pretty easily.

check the fuses on the power supply --no back door??? that seems odd--more surprising is that you have had it three days and didn't know there wasn't one until just now??
-
ive been playing it constantly until it died now i look thru the coin door area with a flashlight then i noticed a problem.. my entire back side is bolted together.
and one more thing i called the guy he said he had this machine for 10 YEARS without problems he had it put in a barn..
if my machine is fixable how much would it cost for a tech to fix it??
i will be getting a multimeter to test it.
what would i be testing?? the power supply or PCB??
-
Where are you at, William? If you're anywhere in the KC area, I can come by an take a look at it for you... I know it's a long shot that you're anywhere near me, but ya never know.
Digital pics would help a lot.

I'm thinking a switch. Or maybe a fuse.
If you get the multimeter, then you open the back of the cab, plug the thing in, and start following the power supply. Hold both probes in one hand only. Keep the other hand behind your back.
Repeat: KEEP ONE HAND BEHIND YOUR BACK!!
Find where the plug goes into the cab. follow the wires. when you see a place where the wires are exposed, look for a black one and a white one. You should get 120 V when you touch the probes (with one hand only. Keep the other hand behind your back).
Just keep following the power wires. Eventually you're either going to find a fuse, or a switch that power isn't flowing past. If you get all the way to the power supply, then test the leads coming out of it for voltage. Probably 12v and or 5v.
If you've got power going to your motherboard, and the game is still not functioning, then you've got a real problem I think.
For your purposes, any multimeter will be as good as any other. Home Depot sells some pretty decent ones for $20 or so, but even the super crappy $12 meter that Radio Shack sells will do the trick.
Did I mention you should keep one hand behind your back? And wear rubber sole shoes. Those two things are safety precautions that greatly reduce the chances of getting killed if you accidentally touch a hot wire.
I had a similar problem with my cab that had me stumped for a good half hour. Then I remembered that power switch on top of the cab. Doh!

I had a Street Fighter II on location that I couldn't get to power up. It turned out it had an interlock on the boardset drewer near the bottom front of the machine. Someone kicked it or whatever, and dislodged the drawer enough to kill the game.
Good luck. If the entire game is down (no monitor/sound/coinlights, etc) it should be a really simple fix. I realize that everything that I just said is pretty much a summary of the advice from others... Oh well. :)

hey... william.... since you ask what is a multimeter...
I would assume (I could be wrong...) that you don't know much about electronics....
1 thing I would suggest is....
BEFORE you try to poke around inside the cab... UNPLUG first...
and even when its UNPLUGGED... do NOT poke around the monitor part.... the monitor part can still hold a charge when unplugged....
if you have a digi-cam.... then take some clear pics... and post it here.... we can help take a look.... might be able to give you some suggestions....
if no digicam.... then its hard to tell you what's wrong just by your descriptions....
good luck...

Uhhhh..... Do you really think it wise to have someone who is not familiar with multimeters or electricity to do testing on a live cab?

i found someone who would look at it for me he said he will do his best to help me!!
-
i tested the power supply with a voltmeter all i got was.
50 volst on the power supply...then i looked at the back of the board..
i saw a long fuse named
313 3ac
2a 125v
so where can i buy a power supply cheap and this fuse??
-
UPDATE!!!!!!!!
it turns out i had a blown fuse i took the fuse to radio shack they showed me what i needed.
BAM!!!!!!! back to playing street fighter 2
hell yeah!!!
