Tp.mt5510i.pb805 Diagram Best ✦ Premium
To modify this configuration, locate the cluster of small, low-ohm surface mount (SMD) current-sensing resistors connected in parallel between the and the circuit ground plane. Removing one or two of these parallel resistors increases the total structural resistance in the feedback loop. This tricks the driver IC into lowering the driving current, preserving the longevity of the backlight components without drastically reducing screen brightness.
The is a highly popular, budget-friendly "three-in-one" (or combo) Smart TV motherboard widely used by various third-party television brands, including Changhong, Sansui, Walton, and various generic LED TV models. A three-in-one board integrates the Power Supply Unit (PSU) , the LED Backlight Driver , and the Main Logic/Android Smart Board onto a single printed circuit board (PCB).
