What happened here? (PICS)

[urbecrisch]

I was over by a friend's house yesterday to replace his coin lamps with new 12 volt LED's.  He owns a Golden Tee Fore 2005 cabinet.  Since he's purchased it from a reputable Ebay seller, he has had no probelms with the game. 

With the game powererd up, I was moving around a coin lamp in the coin door when all of a sudden the lamps turned off.  I looked in back of the CAB and noticed the power supply did not have it's POWER light on indicating that it had power (PIC).  Also the power supply fan was not active (PIC).  I never looked at the monitor to see if it was running when I was moving around the coin lamps but the monitor does not work now.  There is a GLOW in the neck of the monitor but the screen itself is blank.

The betabrite also does not work but the lights on the marquee work as well as the florescent light under the CP to light up the TB and buttons.

So what happened?  Did the power supply go dead?  How?

I need your expertise!  Thanks.

All of the modern power supplies are designed to shutdown in the event of a short circuit or overload. Perhaps you momentarily grounded or shorted the light socket terminals or your LED was a different polarity.

[urbecrisch]

Thanks for the help Ken.

So did this damage the power supply unit?  How can I get power back to the game?

[unclet]

Nice updated picture Ken ...... must have gotten a new digital camera ...

Turn off the power supply,  unplug the AC cord.  Wait a minute and plug in the cord and turn on the supply.   If you are lucky it will reset and you will be good to go.   If it does not reset you may have caused a short that still exists and it will have to be cleared before the supply will power up again.

[urbecrisch]

Will the short still be in the power supply unit?  How can I tell where the short is?  My friend said he unplugged the chord from the wall, but I'm not sure if he turned off the power supply first.  I will tell him to do this but I'm still wondering where I check for the short.

It appears to have a small circuit breaker on it as well..... have you checked that?

Is the breaker what is circled in the PIC?

[Neverending Project]

That picture is a little fuzzy (or maybe it is my eyes?), but it appears that it says 10 AMP, which means it is either a breaker or a fuse. If it is a switch (I can't tell) try flipping it back on. If it is a fuse, you should easily be able to tell if it is blown by pulling it and looking at it.

[Kevin Mullins]

Yes, that's the breaker.
Worth a shot to make sure it's pushed in and set.

[urbecrisch]

I'll have my friend give it a try and report back sometime tomorrow.

[urbecrisch]

My friend finally tried the breaker and the power supply still does not work.  What next?

[urbecrisch]

If we replace the power supply box, that should fix the problem right? 

Where can we find the right power supply for a GT Fore 2005?

[Avrus]

Have you tried disconnecting the power supply from the associated components and powering it on seperately?  That's the next step I'd take in troubleshooting.

[urbecrisch]

Will give it a try.  Just thinking ahead if a new power supply box is needed I want to know where to look.  Thanks.

OK!!!...... Time to solve this one.....

First..... Check the fuses on the cab and make sure that the fuses on all internal parts of the cab are good. As the marquee is lighting up it's not a probelm of power getting in there.

Second... Check the mains lead that is connected to that supply.. Is there mains power on it. If there is then you got power that far. If there isn't, then that's why the power supply is not starting up and you then need to figure out why there is no power on the lead. 

Third..... That power supply also has an internal fuse. Open the case up and replace the fuse you find on the circuit board.

Fourth.... DON'T buy a replacement from Happs... its just a standard 300W ATX switch mode power supply.  Which doesn't cost the Happ price of $56... They're $10 from most PC Parts vendors.

Thanks Fozzy.  Will report back the results.  Thought there would be a cheaper alternative to Happs.  Hopefully it will only be a blown fuse. Thanks.

Good luck with the fix...

As a quick aside, worth noting that even when moving around/changing low voltage stuff like 12V lamps, it's always best to depower what you are working on first.

Not preaching - I'm talking from experience - having fried expensive kit thinking I could change a 12V fan with the power on...

[urbecrisch]

Right, I always do but in this situation I was merely removing a coin lamp.  Should not have blown power to the supply box.  I did not notice but supposedly the monitor had already lost power before I started removing the coin lamp anyway so it was a weird situation.  I will as usual power off before hooking up the 12v LED lamps.  Thanks.

[Fozzy The Bear]

OK!! That's interesting..... Why didn't you mention that before now... This is almost certainly a mains power loss inside the cabinet and nothing to do with the fact that you changed a coin lamp.

Again! check the fuses in the cabinet there will be more of them located elsewhere... Probably near to the back panel close to where the mains in socket is, you might also find a mains distribution bus somewhere near the back or on the rear side wall. There will be fuses associated with that as well. You may also find some in line fuses in the mains leads inside the cabinet. Meter them all and change any that are blown (remember to turn the power off and unplug while you do this or we'll be changing your name to UberCrispy).

If your marquee light is working and your monitor neck is glowing, it would not be a blown fuse in the primary line.  The only two things that generally will cause this fuse to blow are the marquee light or the monitor.  Also the golden tee power supply that is pictured is not an ATX power supply.  ITS only used ATX power supplies on their red game boards, not on their green ones.  If the fuse is blown in your power supply, it is highly unlikely that you will be able to simply replace the fuse and have it work, as this fuse will usually only blow if your switching transistors, bridge rectifier, clamping diodes, and/or your AC input capacitor in the power supply is faulty.  If you've unplugged the machine for a couple of minutes to allow the power supply to reset and you're receiving voltage to your power supply and nothing is coming out of your power supply, it pretty much means you need a power supply.

*UPDATE*

My friend replaced the fuse inside the power supply and ...presto!  Game works again.  Thanks for the help, especially to Fozzy since he tipped me off to the internal fuse.

One more question about this cab.  If I was to install 12v LED lamps to replace the 5v, can I just tap into the power supply unit with a Y connector and use the 12v and ground connection to hook up the lights?  That's what I did to my cab although mine is running a PC.  My friend has got a dedicated CAB although there is an empty molex connecter where I can use a Y connector for powering the LED's.

Is this OK to do?

The answer to that is a probably yes....... Because the 12V LED Lamps will be drawing way less current than the 5V Incandescent lamps... However, because you're drawing the current from the 12V Bus on the power supply, instead of the 5V Bus you could overrun the rating of the of the 12V Bus. They are independent in a switch mode.

It is however unusual for your coin door lights to be anything except 12V anyway! I'm not sure why they're 5V. Check again that you don't have 12V lamps in there. 12V is the most common, with 6V and 24V being the usual alternatives.

If they are 5V or 6V then I'd suggest that you could put a little 12V wallwart supply inside the cabinet to power your new LED Lamps. That way you can be certain that you're not going to overrun that PSU.

Either that or buy 5V LED's from Randy at GGG..... They are very bright! I mounted 2 (one red one yellow, which gives a bright orange glow) on a narrow bit of strip board, with the resistor.  That then plugs straight into the original lamp socket on the coin door. Works really well.

Below is a pic of the 12v wiring I want to use for the LED bulbs.  I'm not sure if the pic is clear enough but would this work?

I already answered this above......

Yes that molex will give you 12V but are you sure that, you won't be overloading the power supply by doing it?

See above!
