IGT KENO Machine Screen goofed up, any help?

[phxfirefighter]

My IGT KENO MACHINE has the screen all goofed up.  Anyone have an idea what I should check to fix this problem?
I have attached a couple pictures.
 thx  john

The fault is not with the screen, it's with the character generator. This is probably an EPROM on the main board. I would guess it has an address line fault - try removing and replacing the EPROMs as a first shot, in case it's just a poor connection.

Welcome to  !


First question, did you tap on the glass?  Because the sign specifically says "no tapping on the glass".

 

Kidding, of course.  A few questions for you.  Is that a Fortune II, PE, or PE+?  If you're not sure, the fastest thing to do would be to turn the power off, then remove the removable MPU board and take a picture of it to post on here.

Also, did this machine ever work correctly for you?  If so, did something happen to cause it to be in its current state with distorted graphics?

Hi, I had this monitor re-capped about a year ago and it worked fine for a while.  After a couple months this screen would pop up but after it warmed up 10 min it would look normal and play fine. Then it just kept taking longer and longer for the screen to switch over after it was turnede on, until it finally just stayed on this goofed up screen and would not straighten up at all.   I have attached a couple pics of the circut boards.   I am not sure which is the EPROM and wHich of the two is the main board. 
Thx  John

The good news is that the cap job on the monitor is still working fine -- the monitor is displaying everything it's being told to display very nicely.  Unfortunately, one of the boards or chips is flakey, and is telling the monitor to display a lot of junk.

I don't know which platform that is (although I can eliminate PE+, and I think PE as well).  The really curious thing to me is this:





A marking of Bally on one board, and a marking of IGT on the other!  Very odd.

EPROMs, or Erasable Programmable Read Only Memory chips, are the (typically) removable socketed chips on the board.  On the 'Bally' board the two EPROMs with white handwritten labels on them may be related to the program and/or graphics.  On the 'IGT' board there appear to be two EPROMs with yellow labels, under the white tape, which also may be related to the program and/or graphics.

See if you can determine what the yellow labels say.  If those are the graphics chips, that'd be the area to look for loose connections and/or broken/cracked traces on the board.  It seems to me that if you said that it would work after being on for ten minutes that you may have a cracked trace or solder joint on the board that would make a better connection once the board warmed up a little and made a better connection.

I'm no good when it comes to board-level repair, however -- hopefully someone else will chime in here with some better suggestions.

Si Redd came from Bally Technologies before he formed Sircoma which became IGT.  So the combination is not too far fetched.

I have to agree with Op-Bell, that the address line is probably messed up, causing the graphics to fetch from the wrong address.  Re-seating the eproms and looking for any residue that could be jumping pins or contacts would be advised.

John,
I had two of those keno machines about two years ago. I had the same problem with one them that you have, but I was fortunate enough to have extra boards. I put another main board in and it worked fine. My machine also had 1 IGT board and 1 Bally board. The only problem is finding someone that can test your board because for the most part these keno machines are pretty much out of date. I have 4 boards left but they are the boards with the red tabs and they read Bally Assy 400795. I do not know if these will help you. I really never tested them out but you can have them for free and just pay for the postage. On these boards it reads TV keno card #2. I believe you need board #1 and unfortunately about a year ago or so I threw out about 3 of them in the garbage. I do have some extra chips for board#1 and you can have those too. Believe me if you plan to keep this machine any extra parts you find grab them. I still think they are a pretty neat machine.

I removed both pairs of chips (white label, yellow label) from both boards and cleaned them with an eraser and reinstalled (fragile little devils).  The all looked fine, no residue ect.  And the boards looked good, no cracks or burnt areas.  I reinstalled the boards and no change.  I also pulled of a big chip and cleaned it up, no change.  Any other ideas?  I enclosed a picture of the chip that was under the yellow tape.
thx john

hey vette! That's great! 
kudos + to you for helping out another member here on NLG!!!

John,
Give me an address to send them to. I will pack the boards good and secure. I will let you know what the postage will be after I ship them. Maybe these boards will help and maybe not. I feel better giving them to you instead of them sitting in my storage room or throwing them out. I will check to see what else I have. I know I have a extra pen setup including the small board that you can have. I have about 8 of those. I will pack that with the boards and chips. That was the first keno machine I ever owned and I bought so much extra parts that you think I owned 10 of them. Will get them out this week and goodluck with the machine. I have a Fortune 11 keno machine now, the only difference between the two are its holds credits and parts and boards are still around. This machine would knock your socks off if you seen how clean it is. I just had a new monitor installed in it about 8 month ago. Thinking of selling it to get some cash to invest in a Odyssey machine.

Great!        This is way above and beyond, I would like to see a picture of your Keno Machine!  I have 5 bally slots electro mechanicals, 1 IGT video poker that works and one that I am trying to get working.  My wife thinks Im a nut cause I love tinkering on my machines.  I always liked Keno when we went to vegas in the good ole days, so I was real happy to get this one a few years ago. Thank you for your hospitality, I hope I get a chance to do for you.

phxfirefighter,
You should have sent him a PM instead or your address will be all over the world wide web in a few minutes on google servers in india.
You can erase that and paste it into the PM to him.
Google will be broadcasting where you live if you don't and you'll have every Tom, Dick & Harry sending you junk mail to your home...lol

[phxfirefighter]

THANKS!

[stayouttadabunker]

  Good, if you had waited any longer -
you would've needed the rest of the dept to put out the fire
from your honey screaming at ya for all the junk mail you would have gotten...

Nice looking game room there, John.  K+ for the picture.  It's like stepping back in time to see all those classic machines next to each other.  Neat stuff.

Hi guys,
Well........guess what???? I have an IGT Keno machine with exactly the same problem as is being discussed here. My picture is also goofed up! My machine is pretty much the same one as is be talked about here. I inquired about my problem a while back, but was not able to get an answer to my problem. Maybe, somebody that's in on this discussion, can give me some help too. That would be greatly appreciated. Here are a few pictures of my machine and the boards. One board has the same part number as in the discussion. The other board, is not quite the same. It is a Sircoma board with the following noted on it: Master Computer Assy-510225. I was limited to posting two pictures, so my boards are not being shown.
THANK YOU!
Jerry

Here are pictures of the two boards that are in my machine.

[ucanwin]

phxfirefighter................if you have any luck getting your Keno machine running.......sure would appreciate it if you could give me some tips on what exactly your problem was and how it was solved. Thanks!

Still not running, tried the things suggested in this post but nothing has changed.  Hoping for some more help.

Hi John,
Thank you for your reply. I was beginning to wonder....if there was anyone really out there, ha!
I posted my/our problem again in another posting, but so far have received one response, and believe me.....I am grateful for that one.
Did you have any luck with determining which chip/s might be the graphics chips?
The only programable chips on my boards are as follows:
Position 10 on my Sircoma board (the board with the battery on it) is 000-0FFF KN0047-U  o8-21-83 (2-732)
Position 10A on the same board, has no tag on it.
Position #46 on the Bally board is #90601000
Position #47 on the same board is #90601100
My Sircoma board is numbered Master Computer Assy. 510225. It also has a tag on it with 75501304 SG411  P-1850      Modify 4-5-90 Rh
My Bally board is numbered Bally Assy-400795 also has another tag on it... MB11080
I don't know if any of this will help you or me, but right now.....I'm grabbing at straws here.
Best regards,
Jerry

From the orginal pictures two appear to have "gaming" tape on them. These are the oversized stickers. I suspect these control the game play - not the graphics.
THe other two on the other board with stickers on them would be my best guess - but I don't know that - its just my best guess that the ones labled are the ones generally swapped.

You might also try cleaning the edge connectors on the board where they mate with the back plane.

Some kind sole has uploaded both a Fortune I and Fortune II manual. Check the uploads section. Neither are of great quality but hope they help.

[ucanwin]

Thank you Jay, for your input.
I have cleaned the edge connectors and socket for the boards. That didn't help.
Thanks for the manual tip. I'll try to find them, but I'm not very good on using this site yet.
Best regards,
Jerry
