Was it like that during the winter and never greened up or was it green in spring then turned brown?

so I've always had trouble with that patch. last year during the summer, it was yellowish. this year in the spring, it was just starting to green up when i tried not watering my lawn as much. In one week it turned that color. everything else was fine though

If it's just that patch in late August/early September dig it up and re-seed it.

I have seen the window effect before on southern grasses. Those spots need to be deep watered more frequently. It's like the temp was cranked up 10 degrees.
