How did you go on this issue as now I have a sudden issue which appears to be very similar.
1. was playing a game today and all fine
2. played a second game and the sound effects were not there but kept getting the Hoff saying we will be right back constantly through the game so something wasn't right
3. turned it off and waited a minute then turned it back on and had all lights, but no dmd, no sound sequence, ball check and no boot up
4. blew the F8 fuse on the Playfield Power Board (PPB) which is a 4amp which looks after the 50volt supply to the coils
5. replaced the fuse and turned on and nothing, went to pull out the multi meter and dead batteries and broke the fuse remover so can check if I popped another one.
I am still waiting on one part and then was going to do a shop out of the playfield as some of the flipper coils do not have a diode and wrong coils amongst a bunch of other switch tidy ups etc - could this missing diode be the cause????
anyone have any glues / advice.....
