Hi. Very new to pinball machine owning, tech unsavvy. Machine has been working very well since purchased well refurbished 6 months ago. Now, moved it gently 20 feet today. Then after playing for a while, noticed the dotmatrix display not working. Turning it on and off several times, "Display Version A2.01" flashed again and again. Then I opened the back box, jiggled a few things, took the dotmatrix display down and then back up. Now blank screen again.
Any ideas what I may have done?
