Hello I have a Bally Eight Ball deluxe limited edition and the other day I turned it on and out of nowhere all of the displays had the Millions comma flickering when a display was in use with zero points. At the same time I noticed the CONTROL lights a little dimmer than usual. I was wondering if I could get some help in which direction I should be looking. I'm not sure if the two problems are connected I just happened to notice them at the same time and I usually play the machine everyday they both happened the same day

Electronmagic thanks. I did do that to a few connectors in the back box and all the displays. I will try again doing all of the connectors in the back box when i get home.

I tried reseating every connector in the backbox. That didnt do anything

I have all fairly new allteck boards except for the squalk and talk sound board.

Hey @BigAl56, i just saw your response now. The flickering comma is happening all the time when it is not supposed to be on , whether the score is 00 or 100000.
It will say ,100,000 or , 00...i will look for a short and get back to you. And yes they are all original Bally displays. Thank you for your response

I figured out the dim lights are not related to the comma problem
I just replaced the bridge rectifier BR1. The cause of all my control lights dimming was in the backbox. It was my fault. I caused a short with the control lights bare wire powerline to the bracket the soundboard screws into. . I eventually smoked the br1. I trimmed back the bare wire so it wont reach any metal now.and replaced the br1. the lights are all bright now. Its just the commas. And this is hopefully the answer. Thanks again

Also, BigAl56 , are you saying specifically the 7th enable wire, or any one of the 7 enable lines

Ok thank you BigAl56 i will try this as soon as i get a chance.

@BigAl56, sorry for the delay the past month has been hectic between havjng to put my dog to sleep and my wedding i have had no time to look at this problem. I recently replaced all the original connectors on the mpu with molex connectors, so it is not an issue with the connection there. I also had 2 pinscore LED 7 digit displays sitting around, and when i plugged one in that i knew worked perfectly, it had no comma problem.

So does this mean something on all 4 original display circuit boards got fried?
