Just joined the club with a dead LAH last week. I got it for a very very sweet price (considering prices of machines in NZ) and so spent around 15 hours over the weekend trouble shooting the PSB & PPB (as well as the Flipper board). $40 worth of components and its back to working sweet!
It still needs a bit of a tuneup and a full clean, for now I'm enjoying my hard work! I do have one annoying issue and thats the ball getting stuck either behind or under (as in the picture) the wire in the back right VUK - any tips on how to prevent this from happening?
