Vizio M3D650SV

[Nick's Tvs]

Hello, I need some help identifying the burned component on this board "Q32."

Is there anything else I should check for? See the attached photos for more details on the burned component that I need help identifying.

The board part numer is: 3665-0042-0150

All I can tell is that it is MOSFET, need to find out how all 3 legs are connected in the circuit.

Here is how the MOSFET is connected in the circuit.

OK, so the SOURCE pin is connected to the + leg of Cap CE6 and also to the output big tab of the LDO (1084 series) U5, that means it is P-CH MOSFET and it looks like it is being used as a switched to supply the output Voltage at the DRAIN pin. GATE is driven by Q36 (NPN) Collector, when Collector goes LOW the MOSFET is turned on.
I would check the resistance between GND and the DRAIN pin to see if it shows very low resistance that is low enough to damage the MOSFET due excessive current flow.
