Well I toon on this repair for a guy with little hope of getting it going due to it being tho only solid state game ever built by this company and being unable to find any info I thought I was stuffed. Finally had a look at it today.
Started by giving the power supply new fuse holders and reflowing all the connectors re seated all the cables just the basics. Fired it up and the display came on with crap. Re seated all the chips and bingo it fired into life
Still has plenty of issues but it starts and plays which is a great start
