Bally E1000 error????

(1/4) > >>

motogizmo:
On first powering up it flashes _ _ _ _ 2_ for one second. Then error code 0_8._0_ is lit.  Then the coin lock out solenoid is powered.  I look in the book and I don't see anything like even close to this. The buzzer goes off about once every 5 minutes for 3 seconds as if has an open door alarm even if I close and lock the door. I have verified the door switches. I can get the machine to go into test modes.  It shows some lighting issues, but the manual tests don't follow the book very well. The hopper test works just fine. Any ideas.... Please!

Off hand I would say that you have some lousy ram chips, the error code 2 is an indication of a mode 1 (Safe Ram) failure so
I would think some bad bits in the ram.

Try swapping ram chip 1 and 2 around and see if that changes the start up at all.

dhellis:
Wait a second, I miss read your initial error code, you had _ _ _ _2_ and I thought I saw _ _ _ _ _2 so now I am thinking that it is not
ram but possibly either U7 or U8, the buffer chips. I say this because you state that the bell goes off and you have lighting issues.

The 2 IC's are buffer chips (8T28) that buffer the signals going to the IO card. It still does not hurt to swap ram chips but also
try disconnecting the IO board and see if you get your 50 000 code back.

One thing that I have been finding a lot of lately is corroded pins on the IO card as well as on the pins for the ram boards.
cleaning these with a wire brush has done wonders for some of the problems that I have seen

proten:
Here is the error codes.
Maybe this will help.

motogizmo:
Swapping ram ships made not change.  Unplugging the IO board produced the 50_000 error.  Any help?
