In repair scenarios where the IC's protection locks the backlight (often due to aging LEDs), some technicians use a 10K Ohm resistor Pin 9 (OVP) to ground to bypass protection for diagnostic purposes.
First, identify the logo on the chip. Common logos: Sharp, Renesas, NEC, Samsung, STMicroelectronics. Search their product archive or end-of-life (EOL) database. sn51dp datasheet pdf %21%21EXCLUSIVE%21%21
