For diagnostic purposes, technicians sometimes bypass the protection circuit by connecting a 10K resistor from Pin 9 (OVP) to GND. General Control:
The is a specialized power management integrated circuit (IC) primarily used as a high-brightness LED driver for LCD TV backlighting. Manufactured by ON-BRIG , it is commonly found on mainboards such as the TP.S506.PB801 used in television brands like Arielli, Crown, Felix, and Cyberlux.
