My machine is Millport 1000 using Media Mo - can seen photo.
when I turn control on, set homing, and idle for couple minutes later all controller shutdown self, control none working nor reset. then I try power off and on.. I get like this screen - see photo.
so I thinking may be weak power supply or something else?
I have a Leadwell Mitsubishi Meldas M0 controls. Are they some weird Chinese characters? When mine did something similar to that the battery was bad and lost all parameters. I put a remote battery in mine and a external power supply to keep it charged up so I don't lose parameters. Did you try a ram clear and reenter all the parameters yet? Also could be a board getting loose or bad.
