// Symptom, not a part number?
"Screen stays black" isn't a part — it's a clue.
Backlight off, flickering, touchscreen misbehaving, membrane keypad dead — the cause isn't always the screen itself. Sometimes it's the backlight module, sometimes the power supply, sometimes the control board behind it. We narrow it down by phone.

TFT Monitor Repair — What Workshop Managers Ask
Updated: July 2026 · Workshop practice since 1994
Can old CRT tube monitors on CNC controls be retrofitted to TFT?
Yes. CRT-to-TFT retrofits are a core focus of our workshop — for example for Heidenhain BF monitors, Sinumerik OP panels and Fanuc CRTs on Gildemeister CNC lathes. The TFT replaces the tube to match the existing control.
TFT monitor stays dark or flickers — repair or replacement?
The backlight or the panel is often behind it. We repair backlight, panel and touchscreen in our own workshop — or retrofit a new TFT if that's more economical. Quick preliminary assessment by phone: 05221 · 9944770.
Which CNC monitors and displays does ESDI repair?
Screens on Gildemeister CNC lathes: Heidenhain BF, Siemens Sinumerik OP, and Fanuc CRT monitors — as a repair (backlight, panel, touchscreen) or as a CRT-to-TFT upgrade.
The screen on the Gildemeister stays completely black — what to check first?
We've documented the first troubleshooting steps: Screen stays black — troubleshooting guide. If it stays dark, a diagnosis at the workshop helps — or call us directly.
