Thats mine, though LED looks pretty cool. A lil dark but nice. The game has a outstanding lightshow and some of the best Jackpotnoise I've ever heard. =)

It's my fist Pinball and still love this game...but I still need a new credit-display/XPin LED Display. ^^"

The different color bulbs in the Ion Cannon already been installed when i got the game and never changed that. Aren't they the original ones?

Coil transistors on the CPU board would be my guess, but first check the wiring to the coils like Hawk007 said. (Replace all bad TIP122 transistors with the more robust TIP102.)
