LCD Screen Error / Dead Pixels
Anycubic 3D Printer (Resin)
Severity: CriticalWhat Does This Error Mean?
LCD screen errors on resin printers mean the UV LCD panel has dead pixels, is dim, or is not displaying at all. The LCD is a consumable — it degrades over time with UV exposure. Replacement is the fix.
Affected Models
- Anycubic Photon Mono
- Anycubic Photon Mono X
- Anycubic Photon M5s
Common Causes
- LCD panel has reached end of life (typically 500-2000 hours)
- UV LED array damaged the LCD from extended use
- LCD cable connection loose
- Resin leaked onto the LCD panel
- Manufacturing defect
How to Fix It
-
Run the LCD test from the printer menu.
Most Anycubic printers have an LCD test mode that displays a white rectangle. Look for dark spots, lines, or areas that do not light up.
-
Check the LCD cable connection.
Open the bottom cover and make sure the LCD ribbon cable is firmly connected. A loose cable can cause the screen to not display.
-
Replace the LCD panel.
LCD panels are consumables — they are designed to be replaced. Anycubic sells replacement LCDs for each model. Installation takes 15-30 minutes.
-
Clean any resin that leaked onto the LCD.
If resin leaked through the FEP, it can harden on the LCD surface. Gently clean with IPA. Cured resin on the LCD shortens its lifespan.
