Help with b5033ci IGT reel game

Okie reseated the chips and replaced board nothing has changed   sigh...

[poppo]

Next, I would pull the MPU back out and remove the motherboard (the board the MPU plugs into). Inspect the top and bottom for burnt traces. Also inspect the plug that comes from the power supply and plugs into the motherboard (the white one). They sometimes get toasty and no longer make good contact.

Especially that one, as it's a known issue. Pull it and look at the back side. See if the plastic connector looks burnt on one pin.
On the other hand, I don't think you would have stiff reels if this connector were causing a problem.

Bunker might be right about the display being bad, but what's bothering me is that the reels don't spin up once during the power on test. I was almost hoping that the SP socket would be empty.

Ok so I totally removed that board, looks great, its between plastic and what looks to be cardboard, no burnt marks, all the connectors look good i inspected each one. the previous owner told me (who knows) that a jackpot was hit and it didnt work after that??  maybe that helps

Not really. BTW, the candle is not flashing is it?

The only other thing I can think of that doesn't require locating another MPU and swapping it, is to pull the CMOS chip. That is the one next to the game and reel chip. It is the one that is battery backed up. Pulling it will make it lose it's memory (just pull it out for a couple of seconds and then plug it back in). It won't hurt anyting, but there could be some corrupt data that might be preventing the machine from booting. This is  where having a spare MPU really comes in handy.

I agree with Stat that I don't think the display is bad because you are not getting the initial reel spin. That tells me the machine is 'locking up' before it gets to that part of the program.

When you had the MPU out, did you check all of the pins on the bottom of the MPU? Spmetimes one will get bent and then the board will not seat all of the way.

the fact that the reels have voltage going to them (stiff) and the 25 cent denom. lamp is lit (1st.photo)  rules out the white connector.

with the door closed and ready to play mode, did you try and insert the flat key into the key switch on the side of the cabinet where the handle is located, turn this and see if you get any change on the displays.

next, I would remove the hopper and (with the power on) undo each fuse cap (one at a time) do not remove the cap, just do a quarter turn and it will become loose and observe what changes. one will remove power all together(flor. lamps go out), the other two, mainly you will see the 25 cent denom. lamp go out and the reels will spin freely, and sometimes you can hear static coming from the speaker. if all this works then your fuses and caps are working .

have you tried to press the white test button (located on the front of the panel halfway down) this is the front panel that holds your board in place. it has all the connectors that come from different areas of the machine.

you could undo the two screws that secure the display and make sure the display is plugged in properly, if you have a meter, you could measure that you are getting +vb across the larger cap located near the connector.

He said he already tried that in his first post.

... i tried the key on the side nothing, I see no error codes or anything on the machine...

[stayouttadabunker]

I'd be checking the +vb on the display caps as Jim suggested, if nothing,
then I'd be swapping out that display panel to get some info from the MPU.
At least with a working display - you can do some trouble shooting.

Unless the MPU is dead and there is nothing to display. Since the reels are not doing their inital spin, I would bet the display is fine. If his candle isn't doing anything either (waiting to hear an answer on that) it would be one more indicator of the MPU not booting

[Jim]

just trying to establish that the board is getting the proper voltages to operate it.  what if the bulbs are burnt out in the candle?

I see that you are in Ohio, send me the board and I can test it for you. 

Jim

[poppo]

what if the bulbs are burnt out in the candle?

I'm just trying to look at all of the symptoms and look at the probability. What are the odds that all of the bulbs are burned out AND the display is bad AND the reals don't do their maiden spin? IMO everything points to it being MPU related. Not to say there isn't more wrong, but that is where I would start.

[r5416]

Candle ( I assume the light on the top ) does nothing, I already checked the bulbs they seem fine, one thing to note, I had taken off the screws on the display and pulled the plug, if I reattach the plug with the machine turned on i see a brief flash (Random) of the LED's this is not a SHORT but I believe just a flash when putting voltage to the display. And again I need to ask would getting a jackpot do anything to make this happen? I am told that's the last thing the machine did. 

Jim, are you in ohio as well?  I would be willing to send you the board to test.  Also, the key does nothing. Thanks

[Jim]

And I have to agree, but you could put 100 known good boards in that machine, and if the power supply is not supplying the right voltages, none of them will work.

Yes I am.

FWIW, when I have a dead MPU, the LED display will flash breifly when powering up. But of course it will not display anything after that.  So again IMO I think your display is probably good.

[stayouttadabunker]

Getting the jackpot does not put a machine out of order - casino personnel do...
That machine may have been horribly mishandled and someone with a fat pair of hands holding a set of pliers
and screwdriver's shorted out your display board.
(This of course is only one scenario...    )

Did you see if the candle's lamp has continuity with a multimeter? 

The flashing of the display's LEDs doesn't really tell me anything other than the fact that
you haven't yet checked the reading of the +vb on the display circuit board.
Secondly, applying live power to a circuit board like that - is never good. 
You're suppose to utilize the power button. 

However, Poppo does think that it's okay and I don't mind agreeing with him.   
Do you have another MPU to put into the machine to try?

 

[poppo]

However, Poppo does think that it's okay and I don't mind agreeing with him.   

No, I don't think it's ok to plug in a board with power already applied. 
I was only noting that I have seen the LEDs flash during power up when the MPU was dead.

I suppose it's possible the display is bad, but I still think there are too many other things that don't work that point to there being a problem with the MPU. If it was just the display, the reels would probably spin and maybe some button lights would come on and the candle should flash.

Also I would take whatever the previous owner said with a grain of salt. For all we know he plugged in the SP chip backwards at some point and fried it.

[r5416]

OHHHH  May have something here, as per your suggestion i turned the caps on the bottom one i see reels loosen as i loosen the cap, on the middle one same thing, but on the top one i saw heard nothing, if I swapped the caps i could hear a popping sound on speaker, im sure at the least one of the caps are bad.  where to find one of thoes?

UPDATE

Ok now i have a different cap in, I get a 1 on winner paid and 0 on the coins played with the yellow (Bottom) candle flashing?

[r5416]

Un real i actually caught the candle during FLASH hahahaha  So now what?

[poppo]

Can you play it now? If not, what does it do?

BTW, I thought the fuses/caps were checked early on.

[r5416]

Until i got the suggestion to loosen the caps and watch/listen for something to change all i knew to do was check the fuses, but no at first i could see 3100 error on the display but now nothing but flashing candle and the display i described earler.  where do I go from here I cannot play the machine quarters still fall through

[stayouttadabunker]

Go buy some fuses...please
Get the right ones instead of messing around with the wrong stuff!!!


Here's an example...you have two bolts in your hands, you need to put a new bolt
in the hole that hold's your airplane's wings to the airplane.
One bolt is plastic and the other one is stainless steel and they're both the same size...
Do you put the plastic bolt in there to hold the wing to the fuselage?

You can...    



Is it THAT difficult to use the right stuff?

[r5416]

the proper fuses are installed 8amp 6amp 8 amp

[poppo]

Look at the coin comparitor and make sure you have the same type of coin you are using. It's hard to see from your picture if that is a quarter or a token in there.

[stayouttadabunker]

Good Good! Thanks!

Did you get a chance to pull the CMOS chip as Poppo suggested?
That may help reset the MPU if you do not have a clear chip.
Can you swap chips?
Put in a fresh known working set of SP and SS chips to see if the chips are okay.

[poppo]

I think he is ok now. He just the needs to get it to accept coins.

BTW, I knew the display was proably good.  And I think no power is technically 'MPU related'.
