I recently changed some of the incandescent bulbs over to leds. With the door open and power on, I noticed a burning plastic smell and a fair amount of smoke. Pulled the Processor board and noticed a burnt processor chip (see pics). Not sure what this chip controls or if its replaceable but would like to get to the bottom of this and determine if the bulbs were a factor or just a coincidence. Thanks. (See red box for location of chip on full pic)

Don't know for sure if those bulbs did it but you cannot replace those chips, they are soldered on that board
-
those items are not chips but transistors they can be replaced. will look at the schematic and tell you what may have happened. was it just Q-5 that got fried?

Not sure if this is your problem but something to be aware of,,,
Some brands of LED's have their wire leads done in a way that will cause a short in slot machine use. I don't remember the details but there has been much discussion about it here on NLG. Take a close look at the LED's you installed, see if the wire leads are both on the same side of the LED base, or if they are on opposite sides. That may be what happened to cause your smoke event.
-
Thanks for the info guys. First question, are the chips purchasable? I have a soldering station to install a new one, but not sure if IGT or you guys have access to them. Also, I checked the old and new bulb leads. They are in fact different (old: 2 leads, 1 on each side, new: 4 leads, 2 on each side). Im thinking "rokgpsman" is right in saying these new bulbs caused this problem. If this is the case, is there a place I can find the 2 lead bulbs? Lastly, if the chips are not replaceable, where can I get the 10MHz processor board?

You can look on the topside of the damaged chips to get the part number (maybe) or someone with a good board can read the number for you. I think those yellow chips are resistor packs in dip package, to the right are the transistors or mosfets that actually turn the lamp on or off. Electronic parts can be purchased a lot of places, here are 2 well known ones:
www.jameco.com (http://www.jameco.com)
http://www.mouser.com (http://www.mouser.com)
And of course you can probably find the parts on ebay or from some slot dealers that carry parts like that.
Some wedge-style lamps and LED's are made so that their base has the 2 wire leads only on one side of the base. Other lamps have the 2 wire leads wrap around so that they are on both sides of the base.
Take a close look at the old bulb you removed and the new LED bulb, you'll see the difference. Or do a search here on NLG for something like "I installed LED bulbs and my dang machine caught fire" or similar.
Other folks here can recommend where to get LED's that work with your slot machine and also the ones that don't. In general, I've heard that LED's made for automotive use are often the type that don't work in slot machines.
Also, you may need to inspect other boards in your machine for burned traces (circuit paths), it seems like the button lighting voltage goes thru a lighting board or display board in the door, but I may have that wrong.
In the example below you can see the different way the wire leads can be done.
-
Okay Ill make sure to check that out. Also, JIM, on closer inspection it looks like it may be just the Q5 transistor (Q5 has a crack in the side and solder is melted around the pins. Black burn marks radiate away from it onto the white chip. I believe I have some extra ones around here. Ill see if I cant install a new one.
-
Here's a few short threads about the type of damage that can occur if wrong style LED's are installed and what causes the problem in the first place. Some of the damage depends on what model of slot machine is involved, hopefully your damage will be limited:

Are you sure that "transistor" is not a Q201E3 logic level triac?
-
If you have the LED bulbs where the wire lead wraps around the bottom of the base, then you can just trim back each lead so that it's only on one side. I have done that to some I bought. They are directional. Meaning the will only light if installed in the correct dirrection.
-

Could be. Regardless, the number on the device will let him order the replacement.
-
What color are the sockets you used. Black ones will fry parts white ones will work without a problem
-
Q-5 is a L201E3 acts as a switch to turn on a lamp. Q-5 operates the insert coin lamp.

Thanks guys. I have ordered the transistors online. Also, the sockets are the black ones. Will the white ones work with the 4 prong or would I still have to trim the leads?
-
If you use white sockets no trimming needed.

I would like to just point out that some of the button LED lamps are too big in diameter
and cause the button to stick.
I don't remember the actual # of the right LEDs to buy but whatever you do, don't try sanding papering the bigger LEDs down to fit because they will melt the buttons!
I did that once and and believe me - it don't work! :arrowthruhead:
-
To replace the burned triac - remove the board from it's tray - cut the body off of the triac and leave plenty of lead length sticking out of the board.
Heat each pad with a leg sticking out of it while applying solder.
When the lead starts to move in the hole keep applying heat and pull the lead out with some small needle nose pliers.
Once the lead has been removed clean the hole out with some solder wick, you may have to apply wick on both sides of the board and may have to apply more solder on top of the wick to get the burned solder to flow.
Check and make sure all PC traces are still intact with a Ohm meter.

Thanks again for all the help! Id like to get some of these white led bases that work with the 4 lead bulbs. Where is a good spot to get these. Thanks.
-
Try Suzo Happ online.

Try Suzo Happ online.
The only thing I don't like about Suzo Happ is that they want you to spend like $100 on your order. You can't just place a $10-$20 order with them.
-
Then... how about AG&E in Las Vegas?

Does Spin, Inc have them?
http://www.spininc.com/ (http://www.spininc.com/)
Are you installing new lamp sockets instead of clipping off one side of the LED wire lead?
-

AG&E seem to be a good company. The only thing I noticed with them is that if your not all ready a customer with them, then they want you to fill out forms for a new account and line of credit? Sounds like they are use to dealing again with larger company's. They did not say I had to buy a min amount like the $100 at HAPP.. I have always had good like buying from Spin tho..
-
Since Suzo requires $100 I figured this would be a good time to order the led tube lights as well. Ive attached some pics of both what I believe to be the right wedge bulb bases for my 4 lead leds and the T8/18 led tubes that should work for my machine. If someone could take a look and verify they are correct or send a pic of what I should be looking at that would be great. Thanks.
-
Don't know about those sockets. I know the black IGT sockets will not work unless you clip the leads on the bulb.
I would see if one of our vendors could get you the white IGT ones. I would have to see a picture looking at the pins directly to know if those will work.
-
rokgpsman, yes Id like to install new sockets instead of clipping the leads. Also, these black bases state they are for all leds except #86 which I believe are the stock 2 prong lights that come factory. But, I will also check SpinInc as I have ordered from them before.
-
Checked SpinInc. All they have are the black ones.
-
I'm not saying they won't work because they are black, they may very well work fine since they are an aftermarket item.
I'm just saying you need to look at the contacts inside the socket and make sure they do not look the same as what you already have or you will get the same results.

First off save you money :yes: on the LED Tubes, you have an S+ machine, all the bulbs in that machine operate on 120 vac with a transformer type ballast and starter. you would have to buy a separate power supply to run the +24 vdc LED tubes. :duh:
read reply #7 by rokgpsman 34041 message, the middle one that was posted, see reply 13-14-15, those pictures show and explain exactly what has to be done to run LEDS for the denom lamp and insert coin and coin accepted lamps. Jim from Blueridge showed some up close and good pictures to explain what was going on, read this before you proceed. :talktothehand:
P.S. those wrap around sockets do come in black plastic as well as the tan version. :stirthepot:
Hope this helps
Jim
