S2000 fried display?

[cobra617]

Hey all,
I just picked up an S2000 Jeannie today. I have been out of this hobby for a while and this is my first S2000. I have a decent amount of experience with Bally 6000 and IGT S+. I apologize for the newbiness of this question, but since I have no docs with this, I have no idea on where to look.
 
Everything worked fine on the machine. I had some leds laying around and decided to convert the bulbs to led. I swapped the button bulbs and they were all fine. I then went to swap the bulb in the middle that illuminates the denomination. (25c for mine). I put in what I thought was a good 12V bulb (later I am thinking that it is not a 12v bulb at all). It lit for a second or two and then went out. Then smoke came out of the winner paid/credits/credits played display. I am ok if that display fried as I see them on eBay for about $14 shipped. My issue is that I have no voltage (is this supposed to be 12V?) on the connector that feeds that board (red/green wires, the same source as that bulb that I replaced). I want to address that issue first. Everything else appears to work properly on the slot. I am really hoping that it is just a fuse that blew.

Since I have no docs, I don't want to go poking around without knowing where to look.


Any thoughts?


Thank you.

Check out this thread from the old board for the most likely reason it fried.

Awesome. Thanks for that. I went ahead and ordered a replacement display.


Any thoughts on my 12V (or lack thereof)?


Thank you.

If replacing the display doesn't fix it you may have also fried the IO card socketed on the inner door panel. They are very sensitive to power surges and shorts

Whew. Another inexpensive part. Since I get no voltage reading on the power connector, I picked up a board off of eBay.


THANKS!

check fuses on both boards

they are surface mount and white, usually labeld F1 or the like.

I'm about 99% sure of what I'm about to say, the lights in the buttons on a S 2000 are 14 volt, The light for the illuminated  denomination sticker just maybe is 14 volt. The only reason I'm saying anything is when you get your new parts you might be getting some high readings with a multimeter.

Just a thought. on the distribution box located right behind  the hopper, on the top edge there is a circuit breaker. You can't see the damn thing, it's 3 or 4 inches from the left side and will feel like a rocker switch.

I am thinking if you smoked the 5-5-2 display board, that's why you have no power to the denom harness. It gets its power from the baord you fried.

Thanks for the reply.


I bought an I/O board as well. It was only about $14 delivered. Not too worried about that as I like to have spare parts on hand. I didn't think that the denom board was serially attached to the display board. (Thought they were each directly connected to their 12v source in parallel)


Thanks for the responses!!!!

I checked that rocker switch and it is good.


Thanks again!!!

Here's a pic of both ends of the denom light harness on the 5-5-2 side display (short reel glass). Red & Green wires.

I didn't know about them being serial so I was reading no voltage because I had unplugged the display red/greed wire. When I plug that back in I read 4.4V at the denom light. So that makes me think that it may just be the display.
Since I haven't gotten the docs yet for the S2000 I don't know which wires are the input voltage on the display board. The seller is supposed to email me the pdf early this week.

IGT was some what smart when color coding most wiring in the S2000 for power and grounds.
Usually the insulation color codes are as follows

Red - +13V DC
Orange - +25V DC
Black with red stripe ground/negative for 13V
Black with orange stripe ground/negative for 25V

Green is not always ground. Green is also used for Netplex signals

All the small lamps are 12-14V, fluorescent electronic ballasts/inverters are powered by 25V

i recently had a similar problem with a machine the display had a faulty connector that took out u67 on the mpu (502 board).
