Measure the exact dimensions of the plastic part. That will help narrow down what it is.
Looks like it could be a SOT23-6 package.
Is it a LED driver?

Also, post a picture with surrounding components.

6-piin package: I guess optocoupler, with the transistor at the melted end.  But yeah, without any other context (what is it in?), it's really hard to tell.

I cleaned it off some more and not sure it’s blown, it did have some black stuff running from it to the 100 chip beside it and it could be melted on the bottom. The 100 chip does get hot.

Can anybody tell me what the component labeled 100 is in second picture.     This is what I think the one AW chip is.  https://www.vishay.com/docs/68393/si3438dv.pdf  Thanks

i would say an inductor

and the Richtek Tech RT9284A-20GJ6E    seems a good candidate,   check the pinout vs the pcb and surrounding parts

for the chip  i've seen  smps controller in these packages

if the coil get hot  it means you have some short on the supply line   or a bigger current consumption

not being rude,  but the pcb  is messy / greasy   etc ...   did you try to unsolder things
