Hi there,I have already posts several mails on the struggle with my bally "Big Winner", model E2407-2, and got very good feed-back.most posts are in the requests PSR board, so may this board is a better choice.uptill now:
summary: 1)display code 50000, also after coin insertion, test and reset switches work, after coin the handle can be pulled and machine goes on tilt2) reel 2 and 3 stopped at the same time, advice received to clean latches, cleaned and now latches moving freely on axe3) opening door caused 16 core flatcableconector to become loose from mpu board, type as-2978-22, and one pin broke; flatcable from display to mpu board, no seperate I/O board or ram board, display out
4) made new cable and checked wiring when attached to mpu board and display board with ohm meter; all ok and same configuration as old cable5)display still not working and also test and reset switch not working
6)checked tranformer: E-122-151; input 220 volt ( I am in Holland); output secundair: 10.7V, 5.7V, 11.3V, 8.5V7) checked powerboard, as-2982-5; before display went out the checkpoints gave 5V, 8.3V and 13.3V ; now 0V, 8.0V and 11,6V, fuses are ok with ohm meter
powerboard looks ok, no burnings
what next?

?
is transformer giving correct output?
is powerboard defect and if so which component? ( as good as I could I tried to check components and they seem to be ok)
your input is very much appreciated,thanks

According to your number 7) comment - you lost the 5V. I am not familiar with this machine or powerboard. You either blew a fuse, and have not found it, or you took out what ever generates the 5VDC. You will need to get the 5VDC working to get the machine doing much of anything I would believe.

I don't think you have a transformer problem, the voltages look OK to me if they are AC voltage readings?

EDIT - I looked at the Bally E series manual and determined this much.
The 50000 code displayed is actually good, it means = Remains until some action is taken such as closing door and playing machine, pressing TEST button, pressing RESET button, etc.
The power board - 5VDC is supplied from a voltage regulator Q1. I will suggest that is blown and will need to be replaced. This probably explains why the test and reset switches don't work. It seems strange to me if the 5VDC is not working the displays should not be working. I have actually seen and did a little bit of work on one of these before, just didn't have to get into anything major except replace the connector on the power board. That's about all my experience with this type of machine.

Hi Tony,
Thanks for fast reply,
Problem with the 50000 code is that it stays there after taken action like inserting coin, will be somehow connected with door open system I think, but was not able to solve yet.

The female orange 20 pin connector is rectagular with wires

Did you get the 5VDC working?

You need all 3 of those voltages you measured on the power board in your previous post...

5VDC is now 0VDC, not good. You need to fix this

what next?

?
is transformer giving correct output?
I believe it is - The voltages look good for AC measurements on the transformer

is powerboard defect and if so which component? ( as good as I could I tried to check components and they seem to be ok)
I think it is defective - Q1 is the device that supplies 5VDC to the machine, possibly bad now?

your input is very much appreciated,thanks
Your welcome

Hi Tony,

The door switch on the lower left side needs adjusting or the wires on the switch could be moved to the wrong contact connection.

Hi Tony,
Q1 is indeed dead and I have ordered replacement, so waiting now for the postman to arrive;
Hopefully this solves the problems.

Hi Sunrise Side,
There are two contacts; there is a key switch under the handle which I checked and seems to be ok with respect to open/ close contact.
Second switch is the doorlockswitch, which als works. I was not able to check the wire connection. Will look into thar when machine is working again,
Thanks for advice

An update; replaced faulty lm340t-5; measuring pins on powerboard gives now 5, 8, and 11.6 volt, so 5 volt is now back, but display and test/reset switch are still not working.
Unfortunately I do not have wiring scheme of mpu and hopperboard.
Are there any obvious components to give special attention? Preferably with mpu board on bench as it is mounted to the backcabinet and difficult to reach

Sunrise Side · « **Reply #7 on:** June 02, 2021, 11:57:35 AM »

For the 5000 code does not go away with door closed , there is a switch mounted behind the lower door hinge

Peter321 · « **Reply #8 on:** June 02, 2021, 12:42:22 PM »

In my model there has never been a switch mounted behind the lower hinge

Your display meter is showing 50000 not 50.000? if you have the 50000 only - check your ribbon cable from mpu to IO board or the meter ribbon to the mpu

Peter321 · « **Reply #10 on:** June 02, 2021, 10:23:24 PM »

I was not clear, sorry The code is 50.000
For now display and reset/test switches are not working, start-up, only give tubes light, nothing else, also no sounds like relay. Powerboard test clips show correct values.
Trying to understand faulty beheviour
Any suggestions welcome

These schematics should get you going:

Thanks Ramegoom,

It is certainly a start and hopefully there are similarities with my boards,
Thanks again

in the meantime I had a lot of help from members, especially Trisail; problem seemt to be cpu which is constant in reset mode; eprom tested and are ok; new 2650 ordered and we wil see if problem is solved
Thanks to Ruud in netherlands I have got pictures of schematics and as the 2407-2 is rather unique I will add pictures of schematics

more pictures

Peter321 · « **Reply #15 on:** June 19, 2021, 10:35:52 AM »

last two pictures

Eliminate the door cam switch. Cut the two wires off of it and wire nut them together.

Amechanic · « **Reply #17 on:** June 19, 2021, 05:57:47 PM »

Did anyone else notice that there is a blue wire pinched under the lower hinge switch? I see the one ends unplugged, but I can

Badbaud · « **Reply #18 on:** June 19, 2021, 06:23:37 PM »

It doesn't look connected. The bottom wire of the switch should Ohm out to J2 pin 3 of the I/O board.

I wonder if the blue wire goes there instead?

Peter321 · « **Reply #19 on:** June 21, 2021, 03:42:47 AM »

My machine does not have doorhinge contact, so also no blue wire

On my doorcam switch, which is nc, there are two grey wires at one contact and one white with blue marks.
Directly contacting the two grey wires with the white one does not help.
With power on only general illumination and nothing else, test and reset ared dead and no sound of coils, power board voltage testclips give good values
