Sn51dp Datasheet -

Furthermore, the SN51DP features robust internal protection circuitry, including and Open-LED protection . If an LED in the string burns out or a component failure causes a dangerous voltage spike, the IC immediately shuts down the backlight drive to prevent cascading damage to the power supply or the display panel. Troubleshooting Common SN51DP Failures

According to repair technology forums, the protection can be bypassed to check if the IC is functional or to operate the TV while awaiting parts. sn51dp datasheet

Compensation pin; connected to an RC network for loop stability. REF Internal reference voltage output or bypass option. 10 DIM Compensation pin; connected to an RC network for

Power Supply Input. This pin accepts the incoming low-voltage rail (typically 12V) required to power the internal control logic of the IC. This pin accepts the incoming low-voltage rail (typically
