I agree. Fertilizer burn?

Bermuda Grass. I had Tru green spray a few times over the course of 4-5 months. I haven't personally sprayed or fertilized it.

Anything I should do at this point?

Insecticide, but it will come back. The underground bits live on if armyworms or such get after it. If you lift on the dead looking parts is it still attached or is the root dissolved?

Looks like somebody let the bermuda get too long then tried to mow at the normal setting.

Are you willing to take complete control of the lawn? If you want to do it right, bermuda is simple in theory. Mow at the mower's lowest setting 2x per week. On golf courses they mow bermuda down to 3/16 inch high, so your mower is not going to damage it. Water deeply and infrequently, and fertilize with a high N fertilizer every month or so. That's simple in concept, but mowing 2x per week can be tedious unless you are committed. Note that you are doing most of the work and Trugreen is doing almost nothing.

I would hit the reset button & scalp that all the way to dirt, then give it 2 weeks to come back.
