Hi all I'm having trouble with my gnr I was in the middle of a game and it stopped scoring. So I turned it off and back on again it starts up normally and then dmd displays caution I'd 101,010,10
Game I'd 101,010,101
1 ball missing
And then when I press start the ball launches and everything seem too work but the dmd doesn't to it's normal thing
Any help would be much appreciated
Thanks Matt
And another thing the diagnostics switch isn't working properly
I would suspect bad 6264 RAM or previous battery corrosion on the board / in the chip sockets. Quick and easy to replace the RAM, as it is socketed.
