Just an update on this and maybe more ideas
At the min it will play without sound .lights no t sequencing but staying lit ,and score boards have gone
All Boards tested working ( sound board untested as yet )
I’m getting 5 v at lamp driver board
But not getting a steady voltage at the scoreboards
Any ideas what to try next ,ive changed a few
Connectors and rubbed a few others with sand paper ,those connectors are a nightmare !
