Schottky diodes rectify the low-voltage AC outputs from the transformer, and low-ESR electrolytic capacitors smooth them out.

The 17IPS72 is a multi-layer (typically 6-8 layers) board. The schematic is organized into logical "pages," each representing a power rail or functional block. Your involves cross-referencing these pages against physical measurements using a multimeter and oscilloscope. 17ips72 schematic work
Often, these components short, causing the power supply to enter protection mode.
If the standby is active, but the main 12V/24V rails don't appear, the PFC may not be Boosting to 400V across the main filter capacitor (C100).
If blown, inspect the bridge rectifier and MOSFETs for shorts. If you are currently working on a repair,I
Verify the optocoupler circuit. If the feedback loop breaks, the primary side will shut down to prevent destructive overvoltage.
Locate the current-sensing resistor network on the source pin of the LED driver MOSFET (typically a cluster of low-ohm surface-mount resistors in parallel, such as

Consists of X and Y capacitors alongside common-mode chokes. This network blocks electromagnetic interference from entering the TV and prevents switching noise from feeding back into your home grid. Bridge Rectifier and Bulk Capacitor
