Fun one - the Stern Elvis game I have been repairing for a customer is starting to lose the DMD display.
I tried to re-flow the DMD power board (upper left board on the head), and did find Q5 "loose" in the fit. I hit all the rectifiers, and any connection that looked the least bit questionable, refreshing with fresh solder.
I'm looking for suggestions as to what the best course of action is to repair this one. I can see the Data East TFTC won't be far behind - it's already showing similar symptoms.
