We recently got a LW3 in, a barn find. Fired it up to MULTIPLE issues, as well as severe battery damage to the main MPU. Ordered a replacement Rottendog MPU from K's Arcade, with the latest code update ROMs. Also ordered a new PS, just because. Boards arrived and I installed as directed.
Fired up the machine again and started blowing the F5 fuse on the PPB. Decided to just order another Rottendog replacement PPB. Received and installed in machine. Everything "seems" stable. Tried to start a game, all it does is fire 2 solenoids and then goes back into attract.
Checked all of my boards to verify the connections, noticed my PIA LED on my brand new Rottendog isn't lighting up. Started looking at the various PIA chips and found several weren't seated properly. Reseated every chip, still no PIA light.
I am really stumped on this one. I figured this would be straight plug-n-play (barring any solenoid/playfield issues) but I can't even seem to get the new replacement boards working.
Anyone have any ideas, suggestions, TIPs? Anything? Please help!
