Robotron boots & blank screen - where to check?
I just picked up a very nice looking Robotron cab. Very clean inside, hasn't been used in years. First thing I noticed when it starts is that it would not save the settings. I checked the battery holder, and sure enough, the batteries were starting to leak. Thankfully nothing on the board. I replaced the batteries, and now the machine will start, first screen for factory settings restored" and then "no errors" or something to that effect, and then the screen goes blank. At the very very top of the monitor I can see some alternating colors from the attract screen, but the rest of the screen is totally blank. It displays perfectly during the startup test and inititialization. Where should I start looking on this? My first williams cab.
