Help with SMD IC Identification

[vegaspeaker]

First-time poster here.  I'm an electronics repair hobbyist.  I've never had any formal training.  I took up electronics in college and enjoy the field.

The current project on my bench is a 15" flat screen TV (Venturer PLV76156) with a failed power supply.  The obvious problem was the failed main filter cap.  Unfortunately, it took out several other things with it.  Some SMD resistors were damaged which I already replaced.  The main MOSFET was shorted and replaced.  I now get 170VDC on the main cap and all the way to the MOSFET and input of the transformer.  That's all I get.  170VDC through the transformer.  It's not switching on and off.

The culprit appears to be the IC for the gate.  I'm getting strange, very low, resistance readings on at least a couple pins.

I've tried my best researching for the actual part number of this 6 pin (SOT457?) device.  It's big enough to have a logo on it, but I haven't been able to match that to any company.  As extensive as this list (https://componentstash.com/reference/semiconductor-logos) is, I didn't see it on there.  I haven't been able to match any of the markings to anything that makes sense.  That's why I'm here.  This TV isn't worth much, but if I didn't think I could fix it I wouldn't have started.  Right now this one device seems to be hanging me up.

BTW, the second picture is more representative of what you see in person.

Any help would be greatly appreciated.
