Wanted to buy, WORKING Bally V1000 or V2000 power supply (AS 3088-1) for video poker machine.
-
Have you contacted Alan at K-Lar in Las Vegas. He can repair/rebuild your power supply. You can find KLar on the home page.

Yes, I have. He was of no assistance. Here is his response to me:

On those old power supplies the 5V fails because there is a dual diode in a heat sink that fails, you can't find a replacement.
I have a couple of cases of those supplies in unknown condition, best case I could send you a couple to scavenge parts from.
I sell them for $65 each and of course that price covers shipping also.
How many dozen do you want?

From what I understand is that he doesn’t have any circuit boards stacks to put in his tester to check the condition of the PS. You can’t just put the PS by it’s self. I didn’t understand this till now by sending him an email. He has a couple crates of these and no way to test them. They may work fine.
-
Thanks, but MAY is a big three letter word in this case. I'm not even sure the power supply IS the problem. Just going by what he says. I need to have a known working power supply to move forward here. I'm no expert when it comes to diagnosis of electrical problems. I have (2) of these V1000 machines, one is complete, the other is a parts machine. Both have the (4) board stacks. If I can't find a power supply, I'll probably parts out the machines. I hate to do that. The one machine is in really nice condition, and was fun to play when it worked.
-
I tried to repair a V1000 about a year back. It had a bad board in the stack. The ps was working. Not sure if that guy still has it or pitched it? All I can do it ask.
-
I'd be willing to trade the board out of my parts machine plus a reasonable cash payment for his working power supply. Can't guarantee anything as to the condition of the board though.
-
I can see if that machine still around. According to Alan he has a working power supply that he use on his board tester that he be willing to sell you..
-
Sounds good. Keep me posted. Thanks.
-
Bought K-lar's power supply. Did not correct problem with machine.
-
Did you check the for burnt connectors on the larger plug on the right side of the board stack?
-
No burnt connectors. Problem is, I'm only getting 0.2v at 5v test terminal on power supply board (same as my old board). If board from K-Lar is good, should I not be getting 5v? (12v terminal tests good on both old and replacement board).
-
If you get the same voltages on both PS, then my guess is that you have a short somewhere in the machine? You might try unplugging one thing at a time like the monitor to see if that voltage changes. Something somewhere is pulling it down.
-
It's not the monitor. Disconnected that, no change. However, when I disconnect the large plug on the right side of the stack, the power comes up. I'm assuming that means the problem is in the board(s). But where?
-
If I remember correctly there is a small board that connects the board stack on the front. Make sure it’s plugged in tight. I have had bad crimp connectors in that large plug. What style plug does your have? One type has a removable back on the plug. This style sucks. The other is a long white solid molex plug about 20 pins long. These are what I use. If you have the first style, you might want to try pushing the wires down into the connector.
-
Connector has the removable cover on back. I removed the cover, pushed the wires down, and checked continuity between wires on connector & corresponding terminal on board. All check good. Board on front plugged in tight, all connections clean. No change.
-
Sound like you have the same common problem with these V1000 boards that no one can seem to fix.
-
I appreciate your input. Thanks for trying to help. I guess I'll just tuck these two machines into a corner for now.

I thought you just had one? You have two doing the same thing??
-
Yes, I have two of these boat anchors. One of the machines was working perfectly when I got them. The other had issues. Tried getting the 2nd one going, but it got progressively worse, finally fading away the same way the "good" machine eventually did. I posted on NLG looking for help a couple of years ago (http://newlifegames.com/nlg/index.php?topic=14592.0 (http://newlifegames.com/nlg/index.php?topic=14592.0)). I wound up using the non-working machine for parts over the years. I tried the 4-board stack from the parts machine and it does the same thing, no boot-up, just a green screen. Pulls down the voltage too.
-
The power supply you got from me worked perfectly.
You have a short on one of the boards in your stack.
While watching the 5V output of the power supply remove straps one at a time from one board at a time, see which board, when removed brings the 5V back up.
I would suspect a shorted bypass cap or a IC in backwards.
-
I removed all of the straps one at a time as you suggested, it made no difference. The only way the power comes back up is by removing the large connector on the right-hand side of board #2. I assume that means the problem is somewhere in that board. As far as an IC being in backwards, that doesn't make sense because the machine was playing fine until it died. I did check them however, and all are oriented correctly. I had replaced the (4) caps located on the corners of the board after this issue occurred, obviously it didn't help. (Yes, they are oriented correctly, as far as +/- goes). I also tried doing the same thing with a second board stack that I have, and it responds the same way.
-
Back to basics, send a picture of your board stack please.
-
Here's some pics

More pics

Take some time and compare all of the connections on your power supply against the connections on the one I sent you.
You purchased a V2000 3 card rack power supply from me but you have a V1000 4 card rack.
Make sure mine is compatible.
-
I always thought that the V-Series PS were universal between the V1000 and V2000 models, just like the way they are between the E1000 slot machine and the E2000 models?
-
That is my presumption also, I have never seen an entire V1000 setup.
Larry and I had piles of V1000 boards but after years of storing them, and never having a use for them, we stripped all of the socketed parts off of them and tossed the boards.
I have only seen one kind of power supply for the V1000/V2000 systems but am wondering if there was some jumper option on it to accommodate the system differences.

I remember when you told my what Larry did with those board stacks, I wanted to cry 🤨.. I would have bought a few board stacks if I had known.
-
Well, I looked over the boards as suggested, and I see no difference between the two. It becomes a moot point anyway. I decided to re-install my original power supply to test whether the power comes up with the large black connector on the right side disconnected from the board stack. It does. So, apparently the problem is NOT in the power supply as someone had suggested initially when I first posted my problem a couple of years ago. That's what led me down the path of believing the power supply is bad. I posted pics of the two power supplies next to each other for your reference. So now I have (2) dead machines.......and a spare power supply. Ha!
Just as an aside, the white sticker on my power supply has V-1337-1-91 on it. The K-Lar supply has V-1292-1-127 on it. I'm no expert, but that would suggest to me that both these supplies are from V1000's. Both have the AS-3088-1 on the board. Just posting this info in light of your discussion of whether or not there is a difference between V1000 & V2000 supplies & you saying the K-Lar supply was from a V2000.
