Default Standard Vizio Power Supply DPS-167DP

Hello. I just want some thoughts on a power supply I'm repairing.
I searched the forum and didn't find much on this power supply.

The IC failed. It looked like it exploded kind of. I got 5 off eBay and replaced it (with that terrible rosin solder..)

The IC gets like 9 volts on every pin except for the two separate drain pins that fluctuate between like 10 and 12 volts every half second or so.

The secondary side has no standby voltage (5vSB) and the diode is short and I haven't replaced it yet. Any thoughts on what else I should test? I didn't notice any shorts on any mosfets.

For reference for anyone with future repairs:
The IC is: LD7913JGM6
The TV is: M492i-B2
Manufacturer: Vizio

(also search does not work on this site? odd)
