Hello all, sorry for all of these...but I'm making progress.
I just performed all of the mandatory ground modifications to the boards in my game. I also removed the DataSentry battery. There was a bit of corrosion, but only on the legs of the crystal. Cleaned it with white vinegar as directed. Looks ok.
I also replaced the main power supply filter capacitor that was recommended as well.
Some questions now...
The player # and # of balls display is completely out. Nothing from it that I can see. It did display very very dimly earlier but not anymore. Is there anything I can do with this or is the display shot? I saw on the pinrepair.com docs about rejuvenating them. Any one ever try this?
Also, the score displays are 'pulsing'. I thought the capacitor and the ground mods would fix this, but it did not. Any thoughts about what would cause the displays to do this?
Also, for awhile yesterday, the game was playing and it had background sounds during game play. I found the dip switch that controls this and it's on. Now it's not making the sounds anymore for some reason. I cleaned the switches by spraying them with contact cleaner and working them off and on, still no sound. I'd like to have it back, thought they sounded cool as I've never heard them again. Speech is working fine.
Any ideas?
Thanks
Tom
