Dim Screen Repair
-
Backlight Restoration: LED arrays revived to full lumens.
-
Driver Circuit Rebuild: PWM controllers recalibrated.
-
Thermal Management: Heat sinks cleaned/replaced.
-
Uniform Brightness: No hot spots post-repair.
-
Prologic Guarantee: Peak nits verified.
-
Efficient Service: Bright results same day.
Dim screens stem from degrading phosphors or power-starved LEDs. Prologic measures lux levels against specs. Aging arrays drop 30% light yearly. Dust layers cut transmission 50%.
Voltage sag on drivers causes uneven glow.
Failure Modes
Thermal runaway kills strings. Capacitors dry out. Connectors corrode.
Software limits max output.
Testing Protocols
Spectrometers quantify drop. Current clamps check draw. Thermal probes map heat.
Revival Methods
Strip replacement with matched bins. Driver IC reprogramming. Optic films cleaned.
Thermal paste refreshed.
Pro Tools
Lux meters calibrate. Bin sorters match LEDs.
Value Added
Energy savings from efficiency. Eye comfort improved.
