Just picked up the machine, done a little reading but still a little confused. Seller said it had a ram error message. When I got the machine home, found a dead and slightly corroded varta. Removed the battery and tried to clean it up a little, but I am getting a door open error which I’ve read might be because of the corroding battery. I occasionally get a netplex error as well. I think I have a 500 board, can a 502 or 504 be swapped for the 500 board? Are 500 boards still available? I’ve seen no activity in the vision LCD screen, but I was assuming maybe I would not see life until I finished the RAM reset.
I can post photos if need be.
I like the setup of the machine, so I’d like to get it working, I’m hoping it’s not too far out there. I have a few other slots so I have some working knowledge.
Thanks!

Post a clear pic of your board. Especially the area where the varta battery was.
-
Here is the close up.

That was a bear posting that photo. I used a tooth brush, then q tips with a very weak vinegar solution followed by alcohol. Looking through a hobby microscope, the races look beat up but intact from what I could see. There does appear to be gunk underneath U84 though.
I read that the Varta doesn’t need to be replaced?
Thanks!
-
The Varta area is pretty rough. I'm sure there is at least one bad trace. Looks repairable tho.
-
I’ll send you an email, Lookes.

Okay, I have made it past the door closure issue, and I think I cleared the RAM, I got an EEPROM error, but cycling power made it past that. The point I a, at now is the Netplex is waiting for a response from the monitor. The monitor has never shown signs of life, except for the little fan, that works. I saw a photo that someone else had posted that showed a connector plugged into the (looking at the back of the monitor) far left molex. I don’t have anything plugged into there and don’t see a cable that would.
I did check for voltages at the main connector and I have both 13 volts and 25 volts, both seem strong. One quirk, if I unplug the main connector and replug it in, the whole machine seems to restart.
Are there common failure points on the monitors? Are they available out there if the whole thing is shot?
-
There's a PCMCIA slot on top and on the side of the lcd computer.
Check and see if there's a thin metal card in them.
The slots have a small plunger on one side of them that you push in, to push out the BGM card.
Note: These metal memory cards go completely down into the slots ONLY one way.
Please make sure the power switch to the machine is OFF 1st.
Never pull plugs out or in with the power ON.
You WILL burn out stuff.
That left-most 4-pin Molex connector on the rear panel of the lcd computer is for the connection to the speakers.
-
I’m referring to the 2 pin molex.
There is a card in the top slot.
-
Don't worry about that for now....that's for an aux audio in connection.
Let's concentrate on getting the lcd to work.
It gets it's power from a 10-pin Molex on a harness going to the small distribution circuit board on the back wall of the topbox.
All we know is you have fan power.
Can you remove the back cover of it?
There's a jumper you need to put on the lcd board inside.
can you tell us if there's already one on there or not?
Let me find you a photo from my notes.

That's not a quirk. Most of machine runs off the +13vdc and 25vdc power supply, so when you remove that connector from the motherboard everything loses power. The exception is the Comm board which has it's own 12vdc power supply that provides power to the Comm board and the convenience light behind the bill validator.
-
There is no jumper there.
-
Stick any 2-socket jumper on the [JP1] pins.
If you don't have a jumper, wrap some small wire around them to create a closed-circuit connection.
That way when you power up the computer, it will display the boot-up sequence, and let us know what's going on with it.
-
I put a jumper in and powered up the machine. At first the screen lights up, uniform whitish appearance and slowly starts to show thin colored lines or the blacked out areas. I don’t think the computer behind the display is starting at all. No text on screen.
It is cold in my garage, if that accounts for anything with the screen changing over time. Maybe it’s slowly warming up.
-
Leave it on for awhile....like an hr or so.
Then power OFF the machine , wait 5 seconds, then turn back ON the power switch.
See if you get a better video.
You know...they didn't make these to be located in sub-zero conditions! :Tongue_Out:
Operating Temperature: 32-95 degrees
Storage Temperatures: 32-150 degrees

Okay, this morning I move the slot into my basement workshop and let it sit to warm up. This evening I pulled the circuit board of the vision. I cleaned up the dust/dirt from the little fan and reseated the main cpu and SIMM’s. I didn’t see any signs of damage or burned components. I put everything back together and powered up. Same result. I waited longer and I’m guessing the search for the monitor timed out and I got a “msverify-comm error”.
The onboard fan gets power
The screen and screen lamps get power
No sign of life from the computer portion of the display.
-
I do need to ask...which "screen" and screen lamps get power" are you talking about?
You need to show us a good clear photo of your MPU circuit board.
Do NOT remove nor install anything in your machine with the power switch ON.
I'm assuming you saw the “msverify-comm error” on the blue VFD (Vacuum Fluorescent Display) reel glass display right?
That's telling you that there's no communication between the topbox LCD computer, and the machine's MPU.
The COMM harness for that is the 3 gray wires that come out of the power distribution board running up to the topbox on the left then out to the 6-pin Molex connector on the back of the LCD computer.
The three wire colors on the 7-pin black plastic Microfit connector are:
Gray w/yellow stripe
Gray w/purple stripe
Gray w/black stripe
Are those two harnesses there?
I've attached where they connect to the PDU.

-
Sorry, I should have elaborated. The LCD screen and the lamp that light it are getting power.
Both harnesses are there, when I get home, I’ll make sure that the other end of the 3 wire harness is okay and plugged in.
You are correct, I was getting the comm error on the VFD display.
Should I be getting some sort of text on the LCD screen (with the jumper in place) when the lcd computer is powering up?
-
Yes....if there's no text, or anything showing at all on the LCD screen even after [JP1] is jumped together, we're going to have to check a few other things.
Don't pull that battery out of it yet...it might be okay.
You don't have a the OS card to load it back up if the battery is removed.
I want to let you know, your machine needs every software piece to be correct or it will NOT work.
Let's verify your software as well.
Can you post some good clear close-up pictures of the chips on the MPU?
Or tell us what you see on the labels?
Four important chips...>>>
The long SB chip (U21 socket)
The GME1 and GME2 pairs (U19 and U46 sockets)
The Version chip (U44 socket)
-
Here is the pic of the board
-
I think you double-posted your photo....oops!
It does appear that the SG chips are copies.
They are poorly made.
The labels are covering up the chip notch that is used to orient the chip in the socket in the correct direction.
You need to to lift up the label from the top of the chip body where the last number "2" of "sg252" is, and look under it to see if there's a notch on the edge of the chip body.
I'm going to say it's in the correct direction in their sockets because your MPU is able to get the VFD to display some messages.
But you need to check anyways.
You see how there's a notch on that long SB chip?...all the other chips have to be in the same direction in their sockets.
Were you able to see if the COMM harness is connected correctly?
-
Oops, sorry, I did check, the comm harness is correctly connected where your picture showed. When I moved the chips to the new board, I was careful about the notches. I’ve read horror stories about the notches so I moved each one, one at a time.
-
I think the display cpu is dead. I found an old computer power supply and plugged it in with all other cables detached, same thing. I’m going to look for a replacement unit.
-
I’m trying a few places, and posted to the classifieds, does anyone know who might have one?
-
I know these guys had a couple of lcd units.
They have all kinds of parts, not just glass...>>>

Thanks! I’ll check with them.

Success! The machine lives again. Found a new display and installed, got the red screen. Replaced the onboard battery and it finally came to life. It still needs a more thorough cleaning and a few tweaks, but it plays.
I ordered a clear and key chip, right now the coin denomination is at $.01. Without the Varta, will key changes stick?
Thank you everybody that helped out!
-
Yes....the Varta battery is not needed for your MPU.
Where did you find another LCD computer at?
Or did you just replace the Sharp lcd screen display (Part No. LQ10D421) like in this photo below?...>>>
-
The whole unit, from WSPS Vegas
-
oh okay...yeah those guys have a lotta parts too.
Glad you found one.
What are you going to do with the broken one?
Are you going to repair it?
If not, can I buy it from you?
-
I can probably let you have it if you cover shipping. Repairing it is beyond my skill level. PM me your details if you’d like it.
