can confirm, replace flyback. just had g07 come in on friday in a pretty sorry looking ms pacman cocktail cabinet.
blown f901, tranny tested okay... just replaced the fuse since it was like barely broken (thought it might have been vibration damaged)... replaced fuse.... flyback blew up with great gusto. bang like a .22 fired off in the shop... core pieces flew 20 feet away... top inch of the flyback cracked and blew off ...windings flying out every which way, sparks and copious amounts of magic smoke.
good times.
luckily new replacements are like 30 bucks. not sure if the owner is going to fix it or just toss it. find out tomorrow i guess.
