Title: Spotty display on a Bally V5500 Post by: proten on May 30, 2012, 12:13:32 AM I have a Bally V5500 that has spots on the card faces.
I have two other boards that work great so I know that it is the one board. Could it be a bad video chip or ram? Which chip is which (mains,video,memory)? Title: Re: Spotty display on a Bally V5500 Post by: proten on May 30, 2012, 12:21:18 AM More pictures

Title: Re: Spotty display on a Bally V5500 Post by: proten on November 02, 2013, 05:49:54 PM Ram cleared and no change.
Thinking it may be a ram chip or video chip. Title: Re: Spotty display on a Bally V5500 Post by: dhellis on January 06, 2014, 08:21:11 PM Ram cleared and no change. Thinking it may be a ram chip or video chip. I would think ram chip before I would think of the video chip. I have seen arcade games that act similar and those have been due to bad ram. Any chance you have a schematic for this particular board? I am looking to find which IC(s) control the Deal/Draw buttons so if you have it then it would be greatly appreciated |
