Bally 809 e-series 1000

[filounet]

Hi,

Here is my 809 e-series 1000, it doesn't start

I controlled the transformer voltages primary and secondary it's ok
I controlled the power supply board voltages it's ok
I checked the voltages at the I / O and MPU boards and I have 5 volts output
I control the fuses and they are ok
The I / O card works perfectly on another machine
The memory card works perfectly on another machine
I tried with another identical hooper but it does not change anything
She does not run the tests and sometimes the TILT light is on

I do not know what to do ? Thanks for your help

your win meter is not attached to the cpu (top right corner) - what display do you get when cable is attached?   describe your error.

I did not plug the cable of the display because I have doubts about its connection card(picture 5).
I know from experience that the machine works without even if it is not practical to read the information.
Before when it was plugged in there was no information about the display drive

You don’t need that little board. Plug your win meter into the socket on the MPU.

Ok thanks for the information but what is the purpose of this card then?

I changed the CR4 and CR5 diodes (4004) on the MPU board and the machine is working again

On the other hand the hooper card does not work?
The board is a P2948-360

Post a picture of the hopper board.

The triacs give 80 ohm

Display doesn't work without the card in picture 5
