Re: TCL 65S517 No Backlight, Picture and Sound OK
TS3 is the Gate drive transformer for driving the MOSFET's QW3, 4.
The primary side of TS3 is driven by that LED driver IC U601. I would not remove TS3 at this point.
Need to look up the specsheet of U601 to locate the VCC pin and ENA pins to find out what Voltage it has on those pins.
