I am considering joining the Alien club by buying a year old machine. The pin I am after however has a problem - the monitor on the playfield, I mean in the back of the pinball machine (it reads something like "Loading dock, outer door" on this monitor) does sometimes not come up when starting the pinball machine and then one has to reboot the pin and after that it works ok. I tried to make searches, but could not find a solution for this. Is there a solution for it, what kind of problem is this to fix? Thanks for any info!
