Flickering frustrates viewers—random flashes from loose grounds or dying backlights. Prologic technicians scope waveforms for drops. Intermittent power rails cause 60Hz hums. Cable micro-fractures worsen with vibration.
Dimming circuits fail in PWM models, creating strobes.
Root Causes
PSU ripple exceeds 50mV. T-Con sync loss. HDMI handshake fails.
Overclocked panels overheat chips.
Diagnosis Techniques
High-speed cameras capture events. Spectrum analyzers find noise. Load banks simulate use.
Fix Procedures
Solder reflow under nitrogen. Capacitor farms rebuilt. Shielding foil added.
Firmware patches stabilize clocks.
Specialized Gear
Isolated power supplies test. Frame grabbers analyze.
Client Wins
Eliminates headaches. Perfect motion for sports. Full brightness restored.
