Hi,
I recently bought an older (1996) Hyundai Hi-T30S turning center with a Sinumerik 840C (I think) control on it. We are a Mazak shop, so the control architecture is quite different, so I'm not even sure I actually have a problem; could just be a switch somewhere.
Anyway, I can fire the machine up, zero it out, and actually run a program that was left in memory. The problem being that the monitor remains black at all times; not even a flicker during boot cycle. Does this just end up being a bad monitor as it sounds or could it be something else? I've found plenty of replacements fairly cheap, and an LCD conversion kit just as cheap. With no experience regarding either the Siemens system nor the LCD replacement kits; any advise would be appreciated.
