Factory settings often drive the LEDs at maximum current, causing premature burnout. To lower the backlight current and extend the life of new LED strips, locate the current-sensing resistor bank connected to the source of the LED driver low-side MOSFET. Remove one or two high-resistance parallel surface-mount (SMD) resistors (e.g., 1R0 or 2R2). This increases the overall feedback resistance and safely lowers the output current. 4.
