Just picked up lw3, was working last week before I picked it up and stopped before I got it. What I do know I'd f7 on psb blows with c1 connected. Unplug it and does not blow but only have g.i lights, no display. Any help would be appreciated

Only go gi and back box lights come on with it disconnected. With plugged in lights come on hear audio for a second then relay clicks and fuse blows and all lights go out.

Update, can get game to play, no display and still blows f7 psb.

The Death Star is now operational. Thanks to all who chipped in to help. Everything came back to the PCB, I removed it and looked at it and saw work had been done to it. I also noticed burn spots on the back box that seemed on. Instead of firing the parts cannon at it I decided to let a professional look at it so I took it to Clay and he had it up and running in an hour. According to him the previous repairs were made by someone not fully qualified and turns out they did not trim the transistors they replaced and we're shorting against the back box. He had me up and running and so far this game is great.

On a side note my DMD is missing a line of text so if anyone is selling one please let me know. Thanks again to all that helped
