What we supply

  • LCD panels & backlights for PPU/OP units — often repairable at panel level for a fraction of a complete unit
  • TCU (Thin Client Units) and PCU units for 840D sl systems
  • OP operator panel fronts (OP08T, OP010, OP012, OP015 families) and keypad membranes
  • Complete PPU units — see Controllers & Panels (65+ in stock)

Is it really the display?

A dark SINUMERIK screen is frequently the backlight, the TCU, or the video path rather than the LCD glass — and on 840D sl, a TCU network issue mimics a dead panel. Free help: blank screen: LCD, video or motherboard? — or WhatsApp the symptoms and we'll point you at the right part before you spend.
