Many users and technicians reduce the current to LED drivers to extend the lifespan of the LEDs and reduce heat. With the SN51DP, this is achieved by modifying the current sense resistors. By increasing the resistance value of the low-ohm resistors in the LED return path (e.g., RB837, RB838, RB839, RB840), you proportionally . For example, removing one pair of 1.5 and 1.6 Ohm parallel resistors can reduce current consumption from 260mA to approximately 176mA. The SN51DP is chosen for its efficiency and

If a TV exhibits "backlight fail" (sound but no image), or the backlight flashes briefly, the SN51DP or its surrounding components (mosfet, sense resistors) are often the culprits. 5.
