Dead MPU?

[Harvs]

So.. I happened upon quite a deal on these beasts this wkend.. All was well until..

The Wild Cherry simply needed a new battery.. Simple (so far.. BV needs help but will get to that later)

The Tabasco is a totally different story.

- Once I got her home I fired it up and there was nothing displayed, no reel spin, nothing. Just lights on. I turned it off, removed the MPU and re-installed. Got 'RAM ERROR, Lose data etc', went through the jackpot key, open close door a few times and got it up and running fine. While the wife was playing for a bit it suddenly stopped (no errors, just stopped and went blank). Test button does nothing, nothing showing in the VFD. I can hear a slight change in tone in the speakers (static, off....on...off...) and thats about it. All LEDS on the MPU are on except the red/bottom) I's there anything I can try other then posting a WTB? Or is she fried?

(I did test the Wild Cherry MPU in the machine and it showed the eeprom mismatch? in the display.)

Thanks

I'd check out your power supply and make sure it's fully seated and tight.

I'll give that a shot quick.

Btw, I finally have a machine with SOUND..

[Harvs]

Same.. Nothing but that slight change in static, on.. off....

I will have to revisit this in the AM.. I'm waking up everyone with my filthy mouth yelling at the poor machine.. Ha.

Try swapping power supply from one to the other and check CMOS battery voltage also

Will do.

2.78 on the battery. I then put the MPU in the other machine and same problems. Nothing but the static noise (on. off. on. off ....)

What if any lights are you getting along the edge of the MPU tray?

All amber LEDS on, green also. The red LED will flash for a split second when just turning on. Then back to nothing..

Think I need a new board.. Have one for sale?? Along with a couple batteries and key/clear chips? Ha

[cowboygames]

Which board series are you dealing with? 500's or enhanced 1270?

I'm still a noob so unsure. Says 1952-0    P/N 75510502 REV A

[cowboygames]

That makes it a 502 board. May be a bad board, but I'd try reseating all IC's and replacing the battery first

Ok. Will try that.

Harv,
I noticed you said you have sound now.
If you do end up replacing the board do yourself a favor and get a 504 rev B board.
The rev A board will most likely have issues with severe humm.

Thx. Thats exactly what Roz said.

Now that I jumped a battery on the wild cherry and moved the machine, it is going WILD.. 

Turned on, reels spin like normal, then the display flickers saying 'door open m, door open mb, closure m, closure b', Not in that order but randomly flickering different.. Optics?

Any info would be great. I will happily wire the optics to the cherry switch if this is the case..

Thanks again, and again......

What do you mean by "jumped a battery"?

[Harvs]

What do you mean by "jumped a battery"?

Attached 2 wires to a new battery and soldered them on, keeping the old battery still attached. I do this because I'm still waiting on my key/clear chips that I bought 2 months ago that will never arrive..

Thats why I'm on your site now Roz.. Ha

 

[CVslots]

Wow, that's very creative!  Never heard that one! 

Check the door I/O to make sure it's seated good. Turn off the machine first though.

[Harvs]

Removed the green battery, checked the I/O and alls well now.. 

Btw, My Wild Cherry MPU is a 504 with no sound board. I will swap that out with my Tabasco due to the sound..

THANK YOU ROZ! I will be placing my order shortly..

[CVslots]

Woohoo! Glad you got it going!

[Harvs]

Here are pictures of the BV. It does nothing when the machine is powered on. It is plugged in as you can kinda see in one of the pictures. I have no clue what the 2 dangling wires are for or where they should be plugged in. Together? They are different sizes.

Also, I did order a new MPU, but does a dead MPU cause a complete blackout? Like, when the machine is powered on, it does absolutely nothing.. If I pull the board out and turn on, it at least tests the display etc like normal. And what do the LEDS on the MPU mean from top to bottom.

Thx

Is this same machine from yesterday (Wild Cherry)? Or Tabasco?

Sounds like a power supply to me. Pull your known good power supply and put it in this machine and see what happens. Either it fixes it or eliminates power supply as culprit.

Tabasco. I put the (bad) Tabasco board in the Wild Cherry machine and it was the same, dead. I then put the (good) WC board in the Tabasco machine and it fired up fine. Obviously errors showed because of the swap, but it showed me that the power supply was working with one and not the other. Right?
