Quoted from DrBernd:All of a sudden a new issue came to life: GI flickering, flashers constant on, playfield lamps confused…. turned the game off
Any ideas???
Sounds like a confused Pdled. There are two of those controlling the GI inserts etc.
One is called pdled0 and the other one pdled1. They are daisy chained eg if a data line is corrupted due to no contact to pdled0 also pdled1 will be influenced. Best start is to make sure the pdled boards are properly seated on their piggy back connectors. Push on them to assure this. Are there screws in place which secure the boards to the piggy back.
Prior to pushing the boards touch a grounded spot first to get rid of any built up ESD.
Let me know how you get along.
Oh, and what is your serialnumber ?
