IGT S-plus Repair Difficulty / Chip Sets?

[knagl]

I installed the lVc123 chip but it doesn't seem to be doing anything. The machine did something but it was so fast that I can't tell you what it was. And now nothing.

Could the battery be dead?

A dead battery will give an error code of 12 on the LED displays.  Did you have an error code showing?

Did you press the self test twitch after you put the clear chip in?  Make sure you've done all of this to clear the RAM:

- Remove the chip in the GAME PROM socket.

- Replace it with the IVC123 clear chip.  Make sure that the notch in the chip matches the notch in the socket (look at the other chips on the board if you need help).  That is, the notched end of the chip goes towards the notched end of the socket.  Ensure that all the pins are seated correctly in the socket.

- Turn on the machine.  Wait a few seconds.

- Press and release the white Self Test switch next to the power switch.  The displays should count up to 999 a couple of times.  Once all the counting is done and there is no more movement of numbers on the displays, turn the power off.

- Remove the IVC123 chip and replace it with your original GAME chip.

- Turn the machine on and follow the instructions for the 61 error you will likely have (instructions here).

That's just it. Nothing is showing now. I didn't turn the machine on before I took the board out. My uncle unplugged the machine I believe, it was unplugged when I took the board out. I removed the game chip in the game prom socket. I placed the IVC123 chip in the socket. I have a degree in electronics and did a lot of projects with chips so I know it was in the socket correctly. Placed the board in the machine. Plugged it in and turned it on. I waited for a bit and pressed the white test switch and something happened for a second. I didn't see the displays and my cousin couldn't tell me what he saw. I turned the machine off and unplugged it. Replaced the clear chip with the game chip and nothing. The machine literally does nothing. We plugged it in and turned it on and it did nothing.

There is no error code because there are no lights turning on or anything.

All dead as if it is un-plugged dead? or are any lights coming on like the belly glass and reel glass tubes? If completely dead check the power cord at both ends for fit and damage, check the fuses lower right and power connection to motherboard center of floor behind hopper. and plug something else into the wall outlet to check it..

[AllyRaisin]

Yes. Dead as in unplugged dead. There was the flash of something on the display and then nothing after I hit the white test switch. No lights anywhere.

I'll check all of that. Thanks. My uncle is ready to toss the machine into his fire pit but I really want to get it working now!

Also pull the MPU back out and look at the two large card edge connectors that seat into the mother board for any bent pins, happens

I am leaning towards fuse, power cord or house outlet

Do you have a multi-meter or access to one ?

Completely dead is not a chip or program level event. more like power supply, fuse, power cable, on/off switch, house outlet ...need to check some basic things first then to the multi-meter to continue

[AllyRaisin]

Yeah, I have a multimeter and my uncle is an electrician so I assume he has one as well. I'm heading over there tomorrow and will let you know what I find. If there is anything else I should check please let me know.

Thanks!!

check fuses and fuse caps with meter not eyes!!

let us know

Hey guys!! I finally got the machine up and running!! But it's not quite perfect yet.

- The bill acceptor isn't working.
- It won't store credit. It pays out immediately when you win.
- It isn't making any noise. When you win, no bells.

Any advice on how to fix these?

And thanks so much to everyone!! You guys have been a great help!!

First go to this page and tell us what SP chip you have. We can answer #2 & #3 then.

Since you used a clear chip, you will need to use a set chip to enable the BV.

I concur with the above post.

Reel Sounds, Win noises are features - not broken.
Bill Validator requires activation via set chip.

You need to clarify the information asked.

Are you getting ANY sounds (coin-in or the like) ever?  If not, check the volume knob which is located on the outside edge of the silver tray that holds the MPU board.  Turn it back and forth a number of times (it has a stop on both ends of quiet/off and loud), and then move it to the middle of the two stops.  You can adjust the level later once you start getting sounds.

If not, check the volume knob which is located on the outside edge of the silver tray that holds the MPU board.  

One of the reasons I asked about the SP # was to see if it was a 10mhz or 16mhz MPU or she might be saying "What knob? "

[knagl]

She, but that's a good point, Poppo.
