The playfield of my Target Alpha suddenly went dead. No lights, flippers, pop bumpers, rollovers, etc. The machine powers up, backbox lights up, score reels reset, drop targets reset, and the ball kicks out. But that's it -- not even GI lights on PF. I checked the 4 fuses on the bottom panel and 3 fuses under the PF-- all are good.
Some background: This is a project I've been working on for about a month now. With the help of several forum members, I got it running fine a couple of weeks ago. Since the, I've been in the process of rebuilding the pop bumpers and flippers, etc. I finally got them all reinstalled today and turned it on. Initially, one of the pop bumpers was stuck on. I adjusted the EOS switch and that solved the problem -- everything seemed to be working fine. I then replaced a few bad bulbs and reinstalled the chimes. I turned it on again and that when the playfield went dead.
And direction would be greatly appreciated.
