Bally Pool Sharks Display Issue

[Maycle]

Can anyone help me out with my bally pool sharks machine, I have the top left of the hole display on the left hand side not working and the right hand display sum sections are fading out?  Thanks

I have created a new thread for this issue, so that others can advise on the problem within it's own thread.
Sounds like a ribbon cable issue to me. With the game off, re seat all the ribbon cables and report back.
