I've been encountering trough issues with my Dirty Harry since I purchased it a year ago. There were some other minor problems that were a little more important...so it's taken me a while to get to this one.
The issue is occasionally on multi-ball (I'd say 50% of the time), the game doesn't launch the right amount of balls. Sometimes it doesn't launch any actually. Sometimes, I can bump the game and it will launch the ball
I've tried some suggestions from here - added the trough sleeve to prevent any magnet issues and I also replaced what appeared to be a dead/dying LED transmitter. The problem continued. Recently, I thought I'd tackle the whole thing and replace both transmitter and receiver boards, but the problem remains.
What should I test check now? Does anyone have any suggestions?
Thanks for your time,
