Payline light assembly not working

[gunner]

My payline light assembly isn’t working in my Vision series game. I removed it and bench tested it and all of the light work when 12v is applied to each light, but no lights work when installed in the game. Any thoughts on a fix is appreciated.

Was it working previously?

What SB chip are you using?

[gunner]

It wasn’t working when I got the game. My chips are SG000123.

Thanks!

If you've never seen that reel glass display  working, it may of gotten shorted out, or a power surge and died.
Check the connections to it anyways...could be a bad ground wire broken inside or oxidized pins.
People don't realize that it's bad to connect or disconnect electronic boards in a slot machine while the power switch is ON.
There's embedded IC circuits (fuses) near the power entry area that protects the rest of the board.
You may need to place an WTB ad in the Classifieds section of NLG for another multi-line display board.
Hopefully, a member/vendor will spot your ad, and have one to sell to you.

In your photo, I can see that you're using an SB chip SB000414.
The reason why I asked is because some games don't need that reel glass multi-line display...yours however, does have the capability to use it.
That is for the "Munster Match" five credit multiplier, three reel, five line game.
Often we describe that chip this way...>>> SB000414 Munster Match 5CM3R5L
SG000123 GME1&2 pairs requires the ATA10053 file on the PCMCIA device, otherwise known as the CF card that's installed up in the topbox LCD display.
You can check to see if that ATA file is installed or not by going into the machine's accounting pages...it will be in a list of what is installed on the machine.
Do NOT put that card into a Windows-based computer, unless you know what you're doing.
Windows WILL write a 1 byte file to the CF card - rendering it useless.
You would have to know how to remove the file, to correct the disrupted checksum of the program.
We do NOT want to get into THAT right now.

Without any credits on the machine, you could try utilizing display test [4.2.1.3] for that reel glass line display, I've attached a partial section of the SG000123 PSR sheet below...>>>

4.2 Output Tests
This submenu provides access to the output diagnostic test pages and is available from only the Operator
Menu. The output circuit toggles between activated and deactivated when the Spin Reels (Enter) button is
pressed.
4.2.1 Door
Output Test Allows output tests on the player panel buttons located on the main door. The
following buttons are used for navigation and may not appear to respond to
the test: Change (Up), Cash Out (Down), Spin Reels (Enter), and Play Max
Credits (Exit).
4.2.1.1 Standard: This page tests the Change, See Pays, Cashout, Spin Reels,
Play Max Credit and Select Credit Value lamps.
4.2.1.3 Paylines: This page tests the payline lamps. Press the Change and
the Cashout button to select the payline. Press the Play Max Credits button to
turn on the payline lamp and, press the Play Max Credits again to turn off the
lamp.

Thank you. I’ll give it a try.

I tried the output test for the Payline lamps and they don’t come on when tested. Since the light board works when I bench test it, I have to assume either I have a wiring issue between the board and the door IO board ( I’m going to check continuity ) or my game doesn’t have the ATA10053 file on the PCMCIA. I went into the Accounting menu but only found a screen in the “Version” submenu that lists the SBchips installed. I’m not seeing anything referencing an “ATA” file. See attached.

[Stayouttadabunker]

Oh...the LED lamps on the circuit might be fine...they just don't get any power because someone shorted out some IC on that line before any power gets to them.
Now, I'm almost certain someone connected a harness to it with the power switch ON.

Keep looking for other accounting menu pages....there's another page somewhere that shows what BGM card you have installed in the topbox LCD unit....the ATA file would be listed on that page as well.

[gunner]

Could there be a shorted out IC on the belly OI board even though everything else that comes from that board works properly? 

[RB]

It's definitely a possibility. Swap it with a known good one.

[gunner]

I checked the wiring harness from the light board to the IO board and all wires have continuity. So, everything looks good from the IO board connection to the lamp board. I also looked through all of the menus and sub menus for any reference to the BGM card installed, but it’s not there. 

[gunner]

Good news! I got it working. It was the light box board all along as @Stayoutadabunker suggested.  I got a new one in today and the replacement worked. I’m stumped because the original board tested fine when bench tested. 

[Stayouttadabunker]

Oh that's good news Gunner 
I'm glad it wasn't the CF card needing an ATA file.
Enjoy your game!

there is only a connection and traces on that display, you must have a cold solder joint on either the ground or 12 volt pin or the pin itself is dirty. that's the only thing that makes any sense. did you try the old one and wiggle the connector to see if it is intermittent?,

Jim

[gunner]

Jim you are right! I was curious too, so I drilled out the rivets holding the light board to the light box and found a cold solder joint on the back side of the board at the connector. I guess when I was testing the board I put just enough pressure on the pin with the bad solder joint to make a connection and the bulbs would light so the board appeared good. When I connected the board to the game the pin wasn’t making a connection.
