That's the problem 2.02 kohms is way way way off. There are a few possibilities here:
1. R7021 is blown
2. R7022 is blown (both could be blown as well)
3.R7020 is blown (unlikely but possible)
4. The traces between the ISL and R7021/2 are blown OR between R7021/2 and R7020 are blown.
Also a good idea to replace the ISL6259 when you figure out which of the above are true.
