Technicians and DIY repairers frequently note specific components that fail, especially after power surges:
This section takes the low-voltage DC from the SMPS secondary side and steps it up to high-voltage AC (often exceeding 600V AC) to power the monitor's CCFL backlight tubes. Ilpi-354 V.a Schematic
This chip controls the brightness (via PWM dimming) and monitors the current and voltage flowing to the lamps. Common ICs used in these designs include chips from brands like Beyond Innovation or GreenPower. Ilpi-354 V.a Schematic
