Couple of issues - first the display disappeared, you can tell that it has messages, but not displayed. Started as partial, now completely blank. However, game still loaded and was playable.
I changed out the batteries and then the game stopped booting up - no ball in chute, all the start up procedures do not happen and the start button does not turn on. Due to no display I can not see the error messages. I tried another set of batteries - same issue. Looked for corrosion, none.
So first, how can I get it to start up again prior to trouble shooting DMD or will the display cause it to not play?
