Run the manufacturer exposure test with the vat removed, inspect the screen and cable, separate protector damage from LCD failure, and replace only with a compa.
Start hereRun the manufacturer exposure test with the vat removed, inspect the screen and cable, separate protector damage from LCD failure, and replace only with a compatible part.
First safe actionRun the first safe check and change one variable at a time.
Proof targetA small representative test no longer shows the original symptom.
Match the failed area to the visual before changing a setting.
Repair progress0 of 8 complete
Step 1 of 8
Wear eye protection and follow the manufacturer exposure-test instructions.
Keep the problem and target visual open while you make this change.
Why this matters
The masking screen no longer switches correctly.
Setting or checkExposure time
Cannot compensate for dead pixels or missing screen regions.
Expected result
The original symptom no longer appears during a representative calibration or short test print.
Step 2 of 8
Remove the vat and protect the build surface from stray UV.
Keep the problem and target visual open while you make this change.
Why this matters
The display signal is incomplete.
Setting or checkAnti-aliasing
Does not repair hardware defects.
Expected result
Measurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 3 of 8
Run a short exposure test and compare the displayed pattern.
Keep the problem and target visual open while you make this change.
Why this matters
A leak cured on or entered the screen assembly.
Setting or checkScreen type
Monochrome and colour LCDs have different specifications and lifetimes.
Expected result
No new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Step 4 of 8
Inspect the protector for cured resin, cracks, bubbles, or clouding.
Keep the problem and target visual open while you make this change.
Why this matters
Clouding or cured resin blocks UV.
Setting or checkExposure time
Cannot compensate for dead pixels or missing screen regions.
Expected result
The successful change is recorded with printer, material, slicer, nozzle or resin, and date.
Step 5 of 8
Power down before checking ribbon cables or internal connectors.
Keep the problem and target visual open while you make this change.
Why this matters
The screen may be good but not driven or illuminated correctly.
Setting or checkAnti-aliasing
Does not repair hardware defects.
Expected result
The original symptom no longer appears during a representative calibration or short test print.
Step 6 of 8
Confirm the UV light source operates evenly if the procedure permits.
Keep the problem and target visual open while you make this change.
Why this matters
The masking screen no longer switches correctly.
Setting or checkScreen type
Monochrome and colour LCDs have different specifications and lifetimes.
Expected result
Measurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 7 of 8
Replace the protector or LCD only with a compatible part and approved adhesive/seal method.
Keep the problem and target visual open while you make this change.
Why this matters
The display signal is incomplete.
Setting or checkExposure time
Cannot compensate for dead pixels or missing screen regions.
Expected result
No new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Step 8 of 8
Recalibrate exposure after replacement and run a small validation print.
Keep the problem and target visual open while you make this change.
Why this matters
A leak cured on or entered the screen assembly.
Setting or checkAnti-aliasing
Does not repair hardware defects.
Expected result
The successful change is recorded with printer, material, slicer, nozzle or resin, and date.
