Many things. I could be that the throw of your sprinkler heads did not reach those brown areas.
Could be also that the brown areas are on a slope and water won't stay put over that area.
Or lack water pressure such as too many sprinkler heads on at time, or some are broken. Sometimes dirt can get inside the head and needs some cleaning.
Now it could be that you have waterlogged areas, but these are shown as yellowing first, unless it is compounded by some fungal diseases, then you will have brown areas.

Either grubs or mold...don't water at night or in the heat of the day, should be done in the early morning before the heat of the day to prevent mold and fungus. Use a good lawn spread like Grub X for the grubs. If the neighborhood dgos and cats are using yor lawn for a litter box, the urine is damaging the grass and it has to be fenced in or sprayed with an animal deterrent and the patches have to be cut out and reseeded or sodded.

I even have been designing turf irrigation for a mutually as and that i in many circumstances budget approximately $50 AUS in line with sprinkler, that consists of the sprinkler and the pipe/fittings that flatter it. There are in many circumstances 4-6 pop-up sprinklers (rotors) observing the water tension/pass on your section. upload a valve (that's the automated on/off for each zone) and the different fittings and you may seem at paying around $4 hundred in line with zone. The controller (Hunter is robust so is Toro) and rain sensor could be yet another $2 hundred. upload labour and uninteresting below the driveway and that i could say the fee is tremendously aggressive. you may shrink the fee somewhat via utilising low desity PE pipe particularly that p.c.. do no longer hassle with the rain sensor, I even have in no way seen them as being very powerful, a heavy dew each so often reasons them to instruct the irrigation off. Irritrol does a good soil moisture sensor this is lots greater powerful. be conscious that my estimates are in Australian funds, the sprinklers/controllers and so on all come from the U. S. could be greater low-priced for you. wish this facilitates.

There are a few possibilities here. You may have insect activity (chinch bugs, billbugs, sod webworms, or grubs). There may also be a disease present. This would include leaf spot (melting out), dollar spot, brown patch disease, or red thread. At times we’ve seen underground debris that can cause the problem. Examples of this may be large rocks, some types of metals, or even pollutants. The soil may also be very compacted and in need of aeration (loosening of the soil).

First thing I would do is watch those sprinklers and check where they are spraying to. The sprinklers should spray on the edge of spray arc to the next spray head. Spray heads also get out of order and need to be checked regularly, and adjusted or cleaned.
If all this is in order I would check your lawn for compaction (will need aerating in that patch, use garden fork) or insect attack -eg beetle damage. Its just a matter of trial and error till you find your answer.

Dead Grass
Rake it with a "thatch" rake to get old stuff out, overseed with lawn seed and top dress with dirt.
Fertilize the whole lawn with Hi nitrogen Fertilizer
Water good
You will have green lawn
