The TP.V56.PB801 is a 3-in-1 universal network driver board. It combines the main TV motherboard, a power supply unit (PSU), and an LED backlight driver circuit onto a single printed circuit board (PCB). Key Technical Specifications
"NC" stands for Not Connected . If a component on the schematic diagram has an NC label next to it, it means that part is deliberately omitted from the physical PCB layout.
If the primary side works but there is no 12V output on the secondary side, inspect the secondary rectifier diodes and the PWM controller IC feedback loop (optoisolator). Standby Light On, But No Boot
