Help Identifying a chip

Hello, I have a Vizio S2920w Soundbar which has a blown chip on it. I was wondering if anyone here could help identify it. Its marked 9F 2 and has U7 written on the board beside it. All help would be appreciated!

Hi, I’m having the same problem. Were you able to identify the component? That would be a great help.

@albert45304 from whatever is left to identify the component, this could very well be a Voltage regulator. Check on here You can relatively easy identify if it is a V Reg if one of the middle pins looks a bit odd. Again datasheet will show what I mean by that. You can also desolder the component and check the bottom side for what the center pins look like.
